View Full Version : The edge is on its way!!!!
My new bonzi edge went out today :D You have no idea how excited I am. :) I was just wondering if the Whobbies wet tuned pipe would give me alot more power then the stock canister exhaust. I am going to have to run the can for a while but I really want to get a tuned pipe. What are some good cheep tuned pipes. I would like it to be water cooled if possible. I will post pix as soon as it gets here on this thread. :D
ITS HERE!!!!! I took it out to the garage and filled it with a little gas. It started 3rd pull and first everytime after that. :D Its huge. :cool:
Oh yeah, and the clutch, SWEET. :cool:
How do I get my flexshaft out??? It has a square collet and then it goes the the strut. There is a ferrel in front of the strut. Do I just loosen the set screws on that???

On mine, there is just one setscrew holding it in. If there is no obvious form of attachment, then ask someone who is not completely ignorant of Bonzi drives.
I got it out. Should I pack my strut full of grease also???
I ran it. It was way nicer then the nitros. I can't say much because I didn't even get a tank through it. My friend was sitting next to me saying, "let me drive it". And when I did he about ran it into a big boat and then into shore. It handles waves ALOT better then the little ones.:D Oh, I have water leaking in the stuffing tube when I let it sit in the water. Is there anyway to fix it???

pack in more grease, and remember to take out the shaft after every day you run it, dry it off and put a bit of oil on it to keep it from rusting.
Should I have a gap like this or should it be pretty much up against the trust washers???

You don't trust me do you? PM's are crap it seems :D (in reference to the above /\ pic). Leave some space. Under load, it winds the cable up. Last I recall, when running nitro, you do the same thing? Why would it be any different with this boat. Just a larger space. :cool:
Welcome to the world of gas. Starts on the second or third pull & runs till its out of gas or theres a minor problem. Doesn't get much better. :)
Relax, another run or two & you'll be telling war stories about your nitro days. :D :cool: :) :p :D
So, leave more space then that??? It has a square collet so when it winds up won't it just slide out of the collet??
Doubledog

The spacing you have is fine. After time, I've gotten used to running a little more but thats me & based off of what has been seen on others rigs.
Now its time for some action pics.

Got it running consistant mid to upper 40's now. Nothing like being able to run wide open & not let off. Got the tabs dropped and no crabbing like it used to. The 27 Sikk really pushes hard though we're still trying to find the right prop before considering weight to the bow.

Did it flip?? Will mine do that??? It didn't seem the fastest but that might be because it isn't broke in.

Eric, what radio came with the boat? The article in RCBM didn't go into detail on that.
It is a Hitec Agressor 2 channel AM radio. Cheep but it did the job. I put my Airtronics MX-3 in it.
Ron Olson
07-18-2005, 10:45 PM
I don't blame you. The Aggressor is a good radio but I'd want an FM in a gas boat too.
I put the aggressor in my NH and lowered the price to $175 so hopefully I can get rid of it so I can buy a tuned pipe:D What would be a good pipe to increase performance and get the frigin oil out the back of the boat instead of in the boat?? I was looking at the WWH wet pipe because I would really like to keep it inside the boat. Any imput??

nice boat! just curious, but what is it (the yellow one)? im pretty new to rc boats..really new actually. if i ever get the money i want to get one, which reminds me, if you dont mind me asking how much did it cost you? thanks in advance!
Its a Bonzi Edge. Look at bonzisports.com :D I got the boat for $700.00 because a guy had 3 of them.

ejp... be careful with the BONZI drive shafts they tend to break a lot, they are using new brass furrels that are square and they tend to break(crack)the furrel its self ..im still using the old brass furrel, the only time you have any problem with drive shafts is when you start ajusting the drive shafts height,to much either way and you will snap the shaft... you wanna order some spare brass furrels straight away...it seems that they have moved the problem from snapping drive shafts to cracking brass furrels...and you should have space at both sides of the thrust washer .... ;) ;) ;)
I just gave Bonzi a call to see if I can order a hatch, and I said I would get back to them about that and some ferrels. I informed me that they now have stainless ferrels that should eleminate all the problems with breaking.:D I'm going to order one of those right away:D

nice to see that you have change your radio set up aswell,them basic hitec aggresser radio have major problems with long range... ive change mine to the 3 channel hitec aggresser srx computer contro its the same make but the range is alot better now.... you would think that hitec no about there cheap fm radios have range problems..... :D :D :D
Well, I had this radio so I figured I would keep it and have a nice boat and a nice radio:D
Whats a good pipe for my boat???
Burkey1000
07-19-2005, 09:39 PM
you need about 1/4 inch gap between the thrust washer and the strut, no need for two washers though, bonzi do that but i dont know why as there is no need, one will do, but 1/4 inch gap is a must.
As for the grease, you dont grease the strut, you grease the flex cable in the stuffing tube, but dont grease the strut, there is two lead teflon bearings in there, so no grease in the strut. Some use brass bearings and they need grease, but bonzi drive uses lead teflons bearings.
As for a pipe, decide how your going to mount it, inside the boat or out through the top, centre wrap or side wrap, you need to know because you need to get abit of play with pipe lenth. Rule for thumb for pipes, a long rear cone will give you more over rev of the engine, meaning more top spead and less lighty to just drop off at high revs, a short rear cone will give slightly more bhp but will have a more narrow power band and drop off at high revs, some rev up good and then just hit a brick wall. is the engine stock, will you be tunning it, these matter aswell because if you get it tunned it will move the powerband of the engine and you might need to ajust pipe lenth to suit. Gas two strokes are the best, they just rock. :D
So should the collet at the engine be tight???
I want a pipe that is inside the boat, I would get a side wrap. I just want to get some good performance but I am just play boating. I was looking at the WWH wet pipe but it doesn't give the highest performance. The engine is stock, and I plan on making it watercooled sometime when I get the money. I am just trying to figure out if a pipe will give me performace that I will notice. Are any of the WWH pipes good???
Would the Cooper Quiet pipe give better performance then the WWH Wet pipe???
Hey, DD. Did you notice any performance gain by putting the cooper on??? Where did you get you Sikk 27??
Would this 27cc kit work on my boat?? Would I notice a difference???
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5988414248&category=34058&rd=1
I just called WWH. and they said that they do not recomend the wet tuned pipe for the air cooled. Why??? she said because it requires a contunious water flow. BUT, don't all of them require water flow for the header???? Would I screw something up by going with the wet tuned pipe???
Doubledog
07-20-2005, 02:13 PM
Thats the same kit I had on mine, just ran it one time & sold it. Just the one now is aircooled. Same huge A$# flywheel turning away. So with that, Yes, there's a gain over the 230. Ran four full tanks through mine & its a monster. Tabs are bottomed out making the boat easy as kake to drive & the 27 SIKK pushes it hard enough that its still getting mid 40's easy. I'd like to see a 230rc do that.
Cooper... Yes, thats part of it too. There is a slight advantage with the Coop, but its hard to say. I like it because its so quiet.
My suggestion is to take it easy before doing any mods. Try to get the most performance you can out of this setup & get used to it. Then try modding.
Do you see a problem with using the WWH wet tuned pipe???

07-20-2005, 02:21 PM
ejp....it looks like you spending alot more money than your budget 800 dollars that you said well i think you should have went the full hog and got a bzx4 mod G260 ZENOAH OR A MODDED ZENOAH 23 instead of the AIR COOLED 23 standerd ZENOAH....at least then you now that the engine is already modded than you could have just mess a bout with tuned pipes... well if you are a DIY MAN like BURKEY1000 you could do the engine upgrade yourself,but i Canrt so thats why i got the BZX4 MOD WITH MY BOAT ALREADY BUILD.... MD do good tuned pides but you carnt buy any at the moment....well thats what it says on there web site..http://www.mddracing.com/ ;) ;)

07-20-2005, 02:23 PM
Go back & look at Scorpions boat that he did. Too easy.
Buy a 25 dollar pump, tap the spacer & there you go. How much idling will you be doing? Mine.. only a second or two. Not enough time for it to get hot enough to melt header rings.
Btw, why is everyone hooked on Enforcer wet pipes? Enforcer did not recommend running one on the RC230 becuase its aircooled & makes the engine run hotter or so they said.
Cooper Pipes
Cooper Quiet pipes
Hanson
Chinese copy of the Hansons
CC Racing pipes
Quickdraw pipes........ to name a few.
Personally, I'd buy a Hanson & put one of Mike T's stinger mufflers on it with water injection. That'll quiet it down good.
The thing is, I am JUST sport boating so a full race mod engine is not what I need:D I just want to maybe convert mine to watercooled sometime and put a tuned pipe on it. Does anyone know of a pipe that is quiet and will be able to along the side of the boat inside so it is not seen???
I think everyone is hooked on them because they are cheep and the wet pipe can be put in a cowl because it runs cooler. I am getting sooooooo confused about this pipe thing.:D I just want a tuned pipe.
Doubledog
07-20-2005, 02:52 PM
I'm confused as hell and staying out of it for a while as you are over excited & its not easy to keep up with.
You NEED to run the boat & get used to it before asking so many questions like I said above. That way when you do start with the mod's you see what each one is doing.
Think about it for a minute....
You want a tuned pipe,
You want a tuned pipe that will now fit inside the hull
you don't want a mod engine
27cc conversion
aircooled
water cooled
etc. etc. etc.
and the prop doesn't look like its even been touched. Thats worth at least a MPH or two on the top end and you're already talking about engine mods?
SLOW DOWN. What do you want?
This is gas. What ricco was suggesting is that it needs to be a mod engine to take full advantage of the tuned pipe. With all the money you're wanting to do on upgrades, you could've dropped it on a mod engine.
Most all tuned pipes are the same length. (dealing with the slip on portion)
You can change the header pipes to "wrap foreward, wrap to center, 90*, 100* or even 106* " So that one might fit your style. Most likely you'll need either a 90* or wrap foreward & even then, some might still stick out.
once again, relax. Slow down.

OK. I'm taking a deep breathe. :D I noticed that the prop isn't the smoothest or sharpest. I am just afraid to start hacking away at it. Like I said the post before this. No other mods after the pipe. I just hate the exhaust all over the inside of the boat. :mad:
First on the to do list.
1. prop balancer and files. We're gana make this baby look good:D
2. cooper quiet pipe and wrap to center header.
3. Run it and enjoy the hobby with a nice boat and llllloooonnngg run times. :)

DUDE, if I have ta' tell ya' once more that you're not waisting our time....:D:D:D:D
Check this out.... Go buy some Simple Green or Formula 409 grease remover. Spray over the oily area, let sit, and was with the hose. Done. Grease is gone & stop complaining about it. Nature of the beast.
btw, a Tuned pipe is not going to give you that much of an increase in MPH. Maybe 2 or 3 with a stock engine. Is it worth it? I don't think so. Once again, I'm only running mine because its quiet! If it wasn't for that, I'd probably still have the cannister on.
ok. maybe I'll just stay with the canister and just ejoy the boat like it is:D I just need a little sense talked into me sometimes. Once again thanks a bunch. I am definetly going to buy a hatch and a stainless ferrel. Then maybe a prop balancer and files. Wow, You just saved me over 150 bucks. Thank you:D

07-20-2005, 05:32 PM
yeah like DD says you can gain 2,3 mph extra with justing getting the wright prop and modding it,there is so many things you can do for that extra speed..and the same goes for the tuned pipe..you may wanna get some one to mod a prop for yah ejp ?ive got on of BURKEY1000 SPECIAL PROPS of his old BONZI 50 boat and it works great ...its only a 2 blade but its the best prop ive got yet....maybe you can see if someone will mod you a prop for you someone here may do it for you.... and while you on dont forget to order some spare parts from BONZI like 2 drive shafts,spare brass furrels,pivot pin for the rudder, square or round collet insert .... ;) ;) ;)
well, I am ordering all the stuff to mess with props and a spare prop. I might have to see if DD is using the prop he modded for the G. Bonzi now has stainless ferrels so they won't break. thanks for the help everyone.:D
So, I have things running through my mind costintly. Later on if I get the 27cc conversion would it run as good as yours does DD??? I ask this because won't it be the same cylinder, block and all that but watercooled??? I was also talking to a guy from jims last night and he said that a tuned pipe is like the easiest thing to do to get extra power. I don't know.
Doubledog
07-21-2005, 02:01 PM
Its the same engine, just ones watercooled & air. Don't know of an easier way to say it.
Two ways to do it.... upgrade for $40 (buying the big bore kit you posted a link to) or spend $140 for a new engine. I did both.
The stock exhaust is good. I still don't know why you'd bother changing other than its a noisy joker. Is it worth $140 for complete setup to gain 2-3 maybe 4 mph? Not in my book. Remember, my second G' (used yellow one that I sold) ran 40.0 GPS the first time out. That was with no tweaking. Gas & batteries. Just think, with some work it would've ran better............ :eek:
Well, I am up way above sea level so I have to do everything I can think of to get mine just to run as good as a stock one at sea level. The guy I got my boat from gpsed his at 38 with some tweeking so my boat isn't the fastes you see. Also, doesn't the G come with a prather 275??? Mine has a 270. I am going to get a prop and do some mods to it like you did just not so agressive:D

as far as a tunned pipe goes, its the best mod you can do for instant power increase. Put a tunned pipe on and get the lenth somewhere near right and you almost double the bhp right away. these are all piston induction engines and they arnt very good at there job of max power without a pipe. There is always unburnt fuel leaving the exhaust and a pipe uses this for the next cycle of the engine forcing the fuel back in therfore giving it a supercharging effect, thats how they work. The pipe lenth determines when the fule is pushed back in from the pressure waves going back along the pipe into the engine. There are no set rules for pipe lenth either, everyone asks what the pipe lenth should be, but what is right for one is not always right for the other. You can pick where you want the power to be in the rev range by the pipe lenth, shorter moves it up the rev range, good for long circuts and straight runs and top end speed, longer to move it down the rev range, good for racing shorter circuts or low down power when you want a more instant power, or going round a corner so the engine is just starting on the pipe ready to power out of the corner, a good way to win races. Simple :D :D :D

EJP.... dude , you must be drinking too much pepsi cola or moutanin dew,
lay off the sugar. :) chill out ,
I get dizzy just reading all your questions.
I have an enforcer with the same engine as yours Zenoah G230 RC air cooled, came with a canister, the boat was haulin a** with it but it was too loud for my taste , and wanted to be able to keep going down to the lake and not get kicked out because of a noisey boat,
so I purchased the cooper quiet pipe only for the noise reduction.
it came with a wrap to center header pipe.
it seems that the boat has lost some initial acceleration, but gained some on top.
it is much quieter.
as far as speed goes.... what is it that you want to achieve????
my super G gives me about 4-6 second ( at full blast )or so before it goes from one end of my safe visual point to the other side of the safe visual point (me standing in the middle ) and I have to turn it around and let it come back , this is with smooth water.
I flipped my boat recently because it was too far for me to see when it made the turn and the water was choppier than I thought.
I am estimating that the boat does about 40 MPH , but don't really care if it is any faster or not.
so I gues my question ( in a nice way ) is what is it that you want to achive by spending "boat load of $$$ on conversion ,and pipe. is your boat not fast enough?
Also the engine is air cooled / water cooled , I installed a water pick up (just to cool exhaust rubber gaskets) / because it moves much more water at a more consistant rate than the rudder pick up, the water cools the spacer/ exhaust block / header gasket , than flows to the header / muffler to cool the gaskets there , it does not cools the engine. I do not use a water pump ,
PS: the super G has a 275 stainless prop.
PS2: the boat is fast enough to keep hull out of the water.... sometime more that I want it, only 3-4 inch of the back of the boat is skimming on the top of the water,
some times I like to load it up with fuel(in the fuel tank ) to put more wreight on the mid/ front of the boat.
if this boat would be much lighter it would blow over ( may be)

WOW!!! what a boat. :D This thing will run fast enough for me right now. :)
Have any of you guys seen a difference in speed just by changing a prop??? I put the prop on that I put the barr cut on and could see a difference. No gps even. :eek: I love this boat so I think I'll give it a treat. :D Can anyone say...Manstons Marine tuned Pipe???? ;)
Heres a pic of the pond. Something happened to the camera after I took this pic. Sorry DD. :(

We'll see when my gps and pipe gets here:D It is just the octura like you have. I talked to a guy and he told me to take the airfilter off, the clutch off, and get a tuned pipe and that thing will fly. He said the clutch takes close to 20% of your torque and top end. The boat is fast enough that it will start dancing.:D
Chris LaPanse
07-28-2005, 11:06 PM
I would doubt those figures - a clutch should be locked at high speed, and would only act like a large flywheel (ie: it would slow your acceleration, but not really affect your top end). As for the filter - ditch it - there aint no dust on the water :D

The clutch will loose about 600-800 rpm on the engine so yes it will loose top speed too because of the loss in rpm. As for overall speed through the rev range, ive had boats with them and without them, and i would never use a clutch again, you also need to water pump with a clutch thefore you need a pulse from the engine also a loss there too, and the extra weight. so for me a clutch has no possitve sides to it, you can set your carb or use a channel on your remote to kill the engine, so i cant see positive side, not for me anyway.

just a thought,
the speed increase you are craving will come at a price, or should I say risk.
at $40 your boat is ostly out of the water, being a deep V , it is riding on an edge, as you called it before" it is dancing".
every boat/ hull has its limit, I am not sure what it is for a bonzi or for super G ,
but I can tell you ...after my boat cap sized the first time , and after I read that when gas engines take in water at hight speed , specially with the carb cover removed, you will surely bend a rod (crank to piston connecting rod) + what ever gets damaged / radio gear /.
so what I am saying, I can allready see a post coming up from... EJP......

Rockin' Eric. @!
You've got to remember that the engine isn't broke in good yet until you get three tanks through it. = more speed.
You was ready to do mods because its too slow. ? You've got to slow down & read more posts while letting it settle somewhat.
Yeller Hy, the rudder system is the same as the so called Enforcer XP... its Octura but anodized purple. Adds some real character:)
To make a note: Eric has selective reading because somewhere's I've mentioned about taking the airfilter off and gaining speed. And as far as the clutch, my take is you should've done more homework before purchasing.
If you want to take it off, the do so. Add a new stuffing tube & buy a new longer flex shaft (probably 20 bucks at the most). ITS TOO EASY ! & don't ask how because you know this. :) The main difference between this & your nitro is its 1/4" stuff.

Well, you thought wrong. I already know how to do the rod. :p :p :p The Bonzi 50" can come with a full mod G260 so it is capabile of almost all the speed I can throw at it. :rolleyes: So, all in all I am not real worried about screwing anything up because my boat can't handle the speed. Proper trimming of the strut and tabs and it will stick to the water. :) So, thanks for being worried but I'm not. ;)

Should I have a gap like this or should it be pretty much up against the trust washers???
If you're using a square at the drive collet and/or the ferrule end you don't need a huge space. When the cable winds up the cable slides in and out of the square as needed.
When using a clamping collet with "no square" at either end you should always leave a space as DoubleD said.
I have a square collet. Well, I managed to screw up my prop a little tonight and break a flexshaft :mad: I was taking off from givin her a little checkup and turned and dinged up my prop. :o then about 15 min later it just reved up and quit moving. I'll post a pic tomorrow but I think my drive was set up too high and it stained it too much. Good thing I ordered a spare. :p It got windy over at the pond tonight, This thing is a blast in the wind :eek: It was way stable except for turning it would get a little jumpy. :D :D So, anyone else have idea why it would break. It happened right in front of the ferrel.
Chris LaPanse
08-01-2005, 01:07 AM
Well, sometimes if there is not enough of a gap, when the cable winds up, it can jam and suddenly snap. Or, it could just be bad luck. Also, if you were jumping waves and forgot to let off the throttle in the middle of the jump (in midair), the strain from the prop hitting the water after being unloaded at high rpm could also break it.
I don't think the waves were that big but could be an idea. The gap is not a problem because I have a square collet and had a 1/8" gap and two thrust washers. So, either it is bad luck or the cable binding too bad with the hight strut.
I have some vid of it running but can't figure out how to upload it.:(

yellow-hydro
08-01-2005, 01:40 PM
dude !!!!
the strut is out of alignment big time, it looks like about 1/8- 3/16" elevation,
when you move up the strut like that you should tilt the strut to allow the flex shaftto curve.
the strut not only moves up/down , but can be tilted.
basicly you created a seriuos S curve in flex shaft, no shaft will survive such thing.
I know. I was trying to get it to run looser. I talked to my dad about that and we guessed that is the problem too. Where is yours set on the G??? Should I go down or up to get it to run looser???
Mine won't tilt any more then that.
Doubledog
08-01-2005, 02:15 PM
Mine is level with the bottom.
OK. I'll try there to start. Which way makes it ride looser???
Doubledog
08-01-2005, 02:45 PM
Thought after having ran nitro & doing all the neat mods to your boats that you'd know better than to put a shaft in a tight bind?
You want it to run loose... Consider that maybe the boat isn't designed to. Example is the PSR Fighter, AC Lazer, Seaducer, and a few others. They're for heat racing and like it when there's a bunch of boats churning the surface. Seems the rougher the better. This has been proven and I can say for sure that Speakerboy over at jims did a recent test with his Lazer. Could be the case with your boat.?
Simple things could be this...
Raise the tabs up outta the water
Try a slight trim to the strut like you did, but the Octura setup is not designed to be tilted, but for UP & DOWN movement.
If tilting the strut doesn' work, then maybe a tiny shim might be required between the extension bracket & the stern. You want it to raise the bow and get air under fo'sho!. (my suggestion is to leave this statement alone & play with UP & Down movements... 1/8" at a time. Bottom it out and start moving upwards. You can even take tick marks on the top of the strut to show the adjustments.)
Check the bottom for hooks hug, rockers are loose.
Try more props
and last............. ADD MORE POWER ! That'll get it lose for sure.
I'm kindof thinking the rougher the better. It seemed that the boat ran better when it was windy. it didn't even act like it wanted to blow over:D I know that it isn't surposed to be in at tight bind but I guess I wasn't really paying attention. I took off the air cleaner, adding a tuned pipe, and possibly going to try some props. What would you recomend me trying??? Thanks fot the help and I need some good old rough water to play in:D
yellow-hydro
08-01-2005, 04:40 PM
if you want it loose..... crank the trim tabs out of water,
DD what do you mean it does not tilt ? mine does, well not 25 degrees but it does move enough to get the strut to a "loose " position ,
what I mean by loose , is when you find the angle you want for the prop , tilt the strut so it does not bind the shaft in the strut housing. , you can tell when you spin the prop if it is moving freely,
also slide the prop shaft forward/back to see if it moves freely .
speaking of loose,
I am not sure if it is because of the hull lenght, 46 vs. 50 on your,
but mine runs very loose out of the water, may be toomuch , but I like it that way, not because of the speed , but because it does not hook as bad in the turns, any way at high speed a loose boat /out of the water is = disaster = I flipped it again yesterday, radio gear dry this time, not sure if the engine took a beating or not.
Well, my pond isn't ever very choppy. On a big lake I think it would make a big difference because of the chop. My tabs are all the way up also. The two hulls are designed differently. mine seems to have a lower bow to catch less air. It swoops down and it doesn't look like the G does as much. I don't know though, just guessing:D
Chris LaPanse
08-01-2005, 07:27 PM
That is interesting. The S curve was definitely the problem, though. Mine (the WH SPD III) actually pivots at the place where it meets the transom, rather than being a simple up/down adjustment (probably for that reason). Also, small adjustments make a huge difference. On mine, the difference between plowing and flipping is probably 1/2" at the prop nut, no more. Make tiny adjustments, and see how it goes.
Figures. I got my pipe and GPS today:D Inside my house the elivation is 6911:D It seems to be a good pipe but it leaks at the clamps on the header and muffler. I sealed the muffler with hi temp silicone but I don't know what to do at the header so I can still adjust length. Any ideas???
Does this look better??? :o :rolleyes:
This pipe makes my boat look terreble!!!!!! :( :(

Yes, you're right, the pipe does stick out a bit much. Oh well, what we do for performance. Hey, I will do something like that too sometime, if I ever can afford it with all my other hobbies (my dad thinks I have too many hobbies, I think they're all to interesting to just give one up). I can't wait to hear how it runs with the new pipe, though.
Sorry, but do something like what???:D
Chris LaPanse
08-01-2005, 11:28 PM
like put on a big dry tuned pipe. The wet ones are quieter, and run much cooler, but the dry ones are better performance. I will also pull out the clutch sometime, to save weight and get rid of the water pump.

08-01-2005, 11:39 PM
you seem to be missing a support piece for your muffler ,
that baby will be flying off if you don't tie it to the transom.
I don't want it to be falling on my SUPER G after I lapped you on the race course.... once or twice :)
I don't think I am going to worry about a support. It seems really stuck as it is. The engine seems to have a lot more torque roll on the rubber mounts:D You mean it will fall off after I lap you a couple times and get back in front of you!!!! We'll let the #'s on the gps tell the story:D
yellow-hydro
08-01-2005, 11:55 PM
the only thing supporting your pipe is the exhaust flange at the cylinder, behind it you have a huge muffler which act as a large lever ,
the weight (how ever light it may be ) will pull that muffler down and it will sit on deck of the boat, bouncing
but don't take my (wise :) ) word ....... go to JIM's and look at any boat with sim. setup
GPS numbers :rolleyes: :cool: , mine can read what ever number I want , my car can go really fast ( may be not ) :)
Does anyone have any idea how to make one to support it??? Pic or drawing would be nice:D I will show you it if you would like. It won't be 50 or anything like that, I know so there is no point in lying:D

Something to consider about the length of his pipe is that its got the added stinger on there.
You're at the line many of us come to. Keep the pipe w/ the extra performance &&&& bad looks or go back to the old way. You'll get used to the sight of it once the power comes on. :)
Ah, I don't really mind it now. Makes it look big!!! A hatch would prolly help but don't want one unless the engine is water cooled. It is way fatter then I thought it would be also. Your right, thats all I need for a bracket. Should it be rubber mounted on the exhaust???

This thing hauls the groceries!!!! :D I am going to shorten up my pipe a little. Man, when I first threw it in the water and punched it I was scared!!! this thing hits the pipe and rips :D :D I was really happy with the results except the speed. :( The trim tabs made it really Dance bad :o A bigger pond might help it go faster but I don't have a bigger one. So, it does 40 and could do more. Time to try some props and strut adjustments. :cool: 40mph seems fast though. :cool:

08-03-2005, 11:32 PM
This isnt the best looking fix, but it should work. Seal up the union with some RTV silicon gasket maker. Just make sure there no fuel/oil residue on the pipe when you do it.
I prolly will once I find the sweet spot:D I'll mark it and put some in there to fix it. I think what might have been causing it was on one of the tabs where it was cast their was a ridge sticking up. I dremeled it off to see if that helps.

My opinion is:
Mod 275 #1 --- should be a good prop
Mod 275 #2 --- should be a good prop
Mod X472-3 --- too much
X472-2 Stock --- ? might work, but take some distance to get good speed
X467-2 Stock --- too small
X670-2 stock --- ?
X572 (new, & not worked much) --- maybe a little large
ABC G20 stock --- good dia, too much pitch
Would've included a few more but don't want take his new Rolex as collateral. :D These are just the basics is all.
Eric, wish I had a stock 275 ready for you try along with a stock w/barr cut. That would give you some better ideas. Just remember that before you go chopping one up, run it first. Do one mod & test or you can jack it up. :)

ok guys if ya havnt tried the 572 3 blade, dont bother unless your engine has alot of power and i mean well tunned, not just for high rpm but tunned for alot of torque, otherwise it will not rev out, or anywhere near it, it has a very high pitch, its a very good prop for spooning, and with any deep v hull is one of the best mods that can be done for them.

Seeing that thread makes me regret ever selling the yellow boat. Who knows, next year, the Watermelon might get new paint. Yellow sounds good.:)
I really don't see how your comparison makes any difference. My first thought after checking both boats is the Edge seems to have less freeboard. In other words, the G' looks a little taller in the rear. Should'nt matter as long as the prop shaft is set w/the bottom of the hull.
Just like I posted on the other forum, when you get the props, start with the strut / Propshaft straight & level with the bottom of the hull. The flex will be in a relaxed position. Do not mess with the trim... you only want to adjust up / down movement.
Raise the tabs out of the water & run all the props at the same setting. Get your GPS #'s. Then mark the strut & raise 1/8" at a time using the ticks as your measurement.
Run all the props at that setting & write down the top speed for each.
Raise the strut again and start all over.
You'll get your 40mph & some change I feel. Once you find the right prop, then start messing with the tabs if its not handling properly. Remember that lowering them is going to scrub some speed but help it. With mine, I've got them dropped pretty good and still getting high 40's but it handles like its on rails. Very predictable.
The G' has the power to reach 50 but getting it there & consistantly is the challenge. Next ideas for testing is going to try adding some ballast/weight to the front. Maybe some stick on lead outside on the bow.
Once again, do not mess with the trim but only up / down of the strut. This will serve as an excellent base for your testing. Get too much involved & it becomes a real headache.
I'm stoked for you dude. Rock & Roll.
I'm stoked too. What i was saying is that the G's transome seemes to be 90* with the bottom of the hull. The edge is not. You get more tilt on your strut then I do. All I need is another headache.

Once again,
Make sure the prop shaft is straight with the bottom of the hull. If that means you have to adjust the trim/tilt, then do so as this will be your neutral starting place for the up / down movements.

Something to think about:
Ran yesterday at a local pond. Somewhat small with a guess-timated 150 yds total lenght. Running the same setup thats given best numbers and could not get up to even 40. I don't know if it was a problem with the GPS getting a good reading or what. As they need a good second or two ta' get a reading and with the small pond, it was hard to get a good turn and blast straight from one end to the other.
What I feel was the biggest problem is: the water was smooth as glass. Where before in rougher water, it would bounce around and run loose, the tabs where bottomed out to keep the nose down. Yesterday, it was stuck like glue !
For the first time in my hobby days, someone else got more time on the sticks then I did as it was just too mellow of a run. :p (mellow.... lol. )
Sam at the controls. :)
Well, I wish I could get other people into the hobby but everyone FREAKS out when I tell them it was 700 bucks:D I actually know a guy that wants to build his own boat but just won't do it:( I was to put a 32cc chainsaw engine in one. Can anyone spell cracker box???:D He says he doesn't want it made out of wood though:( My pond is smaller then that I would say and I got mine up to 40 in it:D When the water is smooth my boat doesn't do the best either.
Ok. Heres what I got tonight:
x470/3...33.4mph Good out of the hole but doged as soon as it planed.
x670......27.5mph Ran pretty crapy:D
x572....Didn't gps Ran pretty much like the 670
x472.....38.8mph Now we're getting somewhere:D
x467.....Didn't get to try it due to a burr inside it:( Thougt it might have been a good prop:D
ABC G20... Didn't gps but seems like it would be a good prop if had about 1/4 more of a mile added to the pond:D
SS Modded P275. The boat pretty much jumped out of the water:D Got 40.6 out of it:D
BC Modded P275. Fastes prop on my boat too:D Gave me 41.00:D
I'm hopefully going to a lake this weekend so I'll try them all over again:D Kindof sad that I only go 41 but what can I do:(
Also, I had some trouble this time and last time I went. I was running at the other side of the pond and it just died. Did it 3 times tonight and once last time. Anyone have any idea what could be happening??? Radio glitch that the failsafe doesn't like???
Doubledog
08-16-2005, 02:27 AM
E',
Having not ran the x467, I didn't know about it. Take a round file and clean it out a little to get it fit. Shouldn't take but just a second. From what you've posted, its telling me that your boat likes smaller diameter with a little cup. Would be nice to have a tach so you can see what rev's your'e getting from the mod 275's. If they're up there, then a little more cup could help. Another option would be to maybe reduce a tad diameter on the X472, barr cut, back cut, or even tounge removal.. (don't touch my props:D)
How was the roost? Did you notice any change in it when switching props? The roost from the 275's are fairly low indicating good efficiency. (on my boats anyhow:))
*note* Don't forget to run the stock props you've got against them too as it might be your best bet. :cool:
Post has a lot of hits and lots of people are getting some good info from it. Wonderful thread to say the least.
Forgot about the second part:
Check the venting on the tank. Mine did that. Would run for three laps & die. Took a couple of times to realize that the lines were dry going to the carb. Or a dirty filter, or even the screen in the carb.
If not that, then it could be the failsafe. Have someone stand next to the boat while on the stand and run out a couple hundred yards (or have them do it with the transmitter in hand). Leave the Tx throttle wide open during the time and watch the servo.
The SS275 seem low compaired to all the rest. It made the boat hop out of the water when I gunned it:D I need to do a little tuning to the engine cuz it the L seems a bit rich. I am going to try the x467 and I'll let you know how it goes. I would buy a tach but I am completely out of money right now. Sure wish I could get the 44 you got out of yours:(
Well, the weird thing is. It only does it every once in a while. I am going to check my failsafe and put in some BRAND NEW not charged 50 times batteries. So, all in all I didn't get what I wanted out of this whole prop venture but I may buy a 275 and see how it does.

08-16-2005, 02:48 PM
Yeah, I've thought over and over about tachs but can't justify owning one as I'm not a racer.
Have you taken the carb cover off? Try that but it will need shimming or cutting the bolts shorter. That will give you another mph or two, but be careful when leaning in the high speed needle. That will give you an extra one too over the rich stock setting.
The challenge has presented itself to our buddy Eric. Now whats he going to do? :).

get a lynx lol. The faster you go, the harder it becomes to get that extra speed.
By the sounds of you i dont think it will stop there, you say you just want to be faster than a G well we shall see when you get there you will still want more. Are you any good with a dremel, if so tunning the engine isnt that hard if a bit of care is taken, but the hard part is getting the timmings, now who will tell you theres lol. The low end needle is set by engine rpm when you adjust it so it should be set now anyway if you havnt already. high end can give you alot of speed, sometimes up to 5-7 mph, if its been set realy rich, a big improvement could be had, but be carefull not to go to far, keep an eye on plug color, run it a full throttle, then kill the the engine as soon as you can, then check color, if the engine dies at top speed your already to lean, richen it right away, after that its just gonna get harder and harder to get the speed. The easy tune ups you have done, once youve done all them you realy need to learn about a two stroke engine and how they work, to get the high 50s to low 60s. But it is a great learning curve and knowledge to have, and it sorts the men out from the boys as we say in the uk. Good luck. :D :D
See, I not too lean because my plug is pretty dark yet. I think it could be old batteries and it makes my failsafe kill the engine. I am afraid to do any mods to the engine myself. I pretty much know how a two stroke works and my dad knows them well.
Well, I had my first person come and watch today:D I am going to order a p275 someday when I get some money and see if I can get some speed out of it. Thanks DD and you have a PM.:D

EJP,
how do you like the gasser vs. your nitros.
you don't post anymore about the nitros , how is that mini mantaray project goin' ?
I sold them all. The only thing I own now is the Nitro Hammer Bare Hull:D The mini manta was a weird boat. It would tuck so hard in the corners the prop would lift out of the water. Sold them all so I could get my gasser. All I can say is that gas is way easier, just pull the cord once or twice set it in the water, do a warm up lap and let her rip for 45 min.:D
Well, she floats real nice upside down:D Fliped it tonight and it was the weakest little flip I've ever seen. More like a flop over.:D At the back is sunk to about the sprayrail and about to the airscoop at the front. Got it back and pulled the plug, fliped pulled a little and started first pull. Forgot the gas can and emptied mine out so had to call it a night after about 20min of running:(

I see where you posted about running white gas. Been running it now for a year and love it. Gives good power and seems to idle better than regular. My biggest kicker isn't because of performance gain or whatever some may say, its because it doesn't stink the shop up, stink my car, nor stink my hands when you get some on. The smell is fairly pleasent and not nearly as pungent. Thats the sole reasons for my use. If you're shooting for extra power, mod your engine and be done with it.
Hey man, I didn't know what it did so I was just asking the pros and cons to it. Might try it this weekend if I can get some:D

Don't read deeper into it.:)
Pros... smells good
Cons... TBD
White gas isn't a miracle juice. Simply put. It doesn't add extra mph or slow you down from what the results have shown. Fastrat is a huge supporter of it and I trust his word more than anyones only because he races and does plenty of R & D work to prove his theories.
Funny how white gas has come about after all these years when I've got a weedwacker with umteen years on it running regular gas. :O Do we stick a GPS on those & see what kind of speed were getting? :D So why all the chat about white stuff? Don't know but I'm tempted to start running it in the old JohnDeere wacker just because the exhaust smells nice:D
Btw, have you checked around to see if there are any other Edge owners out there that could offer more input? Just a thought.
No, none. I only know of one and I bought the boat from him:D Said he only got his up to 38 and tried various props with no luck. Well, I also changed to white gas today and it has no smell:D Almost like lacor thiner because of how it evaporates so fast on the ground. Lacor smells though. Hopefully it won't hurt my engine and I can run forever:D

After the first tank or two, you'll forget ever worrying. Just keep the oil mixed good.:)
Doubledog out.
Going on vacation to the North Sea. :)

Just to show it riding on the prop. :cool:

WOOOOEEEEE !
Rockin on now huh? How fast? How fast? :D I'd almost be tempted to lie a little based off the pics. :O
Hey Burkey, just got in from Norderney. Its an island just off the coast. Was tempted to swim over your way and say hello:D
I'll start a new thread tomorrow in the "off topic" pages about it with some pics.
Btw, eric, what props was you using? Did you get more testing done?
That was the SS 275. I didn't try anymore props because a lack of time and parents patients:D I don't know what speed cuz I didn't have my gps in it. To tell you the truth, it was pretty rough so that helped the boat loosen up quiet a bit:D

Eric, if you're running at the altitude that I think that you are, you should be happy with the speeds that you're getting. Being near the Mile-High City doesn't help. Bring it down where the air is denser and you should see a big improvement in speed.
I'm higher then the Mile high city. That lake that I was running at was at 6085. I know that I am loosing a lot of power being this high, thats why I had to get the pipe just to get 40.

Yep, my Manta ran 30-35 out of the box, and hasn't been higher than 41. I've seen reviews where it has run 40 out of the box and 45 tuned, but that's at sea level. Darn this thin air. (hey, at least it improves the performance of my rockets :D). Where I run is just above the Mile High City, at about 5500.
I heard from brian you don't go to the lake much. Why is that??? I was thinking about coming up there this summer but between gas prices and a place to stay I decided not to. Maybe next year.

I've been extremely busy. I try to get out there whenever I can, but my schedule is packed. I can usually only get in 1-2 runs a month.
Sorry to hear that. Before school started I was going about 2 times a week:D I was just looking at those pix again and the pipe doesn't look very big in those pix. Does anyone else agree???

BTW - EJP - I know what you mean about the manta cornering strangely. I took off the left rudder (the big one has duals) to see if I could gain some extra speed by reducing drag, and it started acting up. It would corner slowly, and then as you fed in more rudder, it would suddenly hook (to the right only, to the left, it just wouldn't turn sharply at all). This boat really needs dual rudders - when I have both rudders on mine, it is rock solid, and corners with authority, perfectly smoothly and under full control to the left and right. It's a great design, it just doesn't work well in single - rudder applications (at least with an offset rudder, not sure what a central rudder would do to it).
Yeah, it would just lean really hard. It reminded me also when it was running with out the hatch of those aluminum fishing boats that flop in the front when there is too much weight in the back. The boat needed the CG foward a little I thought.

it would work fine with a single rudder, either one larger one, or better still use a turn fin, atleast then the rudder has something to oppose its force and will turn with one as well as stopping skipping etc, just a thought thats all. :D

yeah burkey1000 is right put some turn fins on that will stop it from skidding round corners... i had burkey1000 put some turn fins on mine and she loves to turn now no skidding about in the water...them spare miss bid turn fins came in handy....lol :) :) :)
Chris LaPanse
08-30-2005, 09:01 PM
Trust me, it doesn't skid. It turns TOO sharply with just 1 rudder (and uncontrollably). 2 rudders makes it more progressive and controllable.
Are you guys ready for a project?? Check this out:D
