OFNA 1/8 Buggys v2.0

[PCC]

Yes, you can do it but you will need to buy a new radio tray and receiver box as well as different front and rear body mounts and front support. The side wings are different, too. You will also need to get a new body as the mounting points between the two cars is different.

[uDi_MP75]

Hey PCC are you the PCC off the old hpiracing forums? im sure you are... i just haven't been around here since near the end of last year (just made a new account today) and you probably dont remember me. I used to me uDi_NMT rulz or something like that on hpiracing.

anyways,

Just dropped in here to ask a little about the 9.5's, does anyone here use and abuse one?

Reason im asking is parts here are cheap, we have a good national wholesaler in the country for hongnor parts, and therefore for purely those reasons, it would be a car perhaps worth dropping my 7.5 for. I still love old faithful more than any taiwanese car, but im starting to see that these (ofna) cars are almost 'more for less'.

After many extreme jumps, backflips, and horrible wot/curb crashes etc however, ive come to like the 7.5's durability... so im basically just wondering how the 9.5 stacks up... is anyone lucky enough to have owned both to give a direct comparison?

im basically asking what breaks here. dont bother sticking up for the kit etc i dont care for that... pretty much straight out 'what breaks'. My 7.5 breaks nothing plastic (its been a year of abuse, so im pretty confident it won't break much in the way of plastic anyway) however shocktowers and hingepin braces bend on mine (soft aluminium) and ive snapped two front shockshafts in the past. Other than that a cracked and smashed fuel tank, everything else holds up perfect.

If i do switch buggies (very unlikely right now) i'd want it to be just as durable if not more.. can i expect that from a 9.5 or not?

not into the hyper7 because we dont have the same support as for hongnor in the hobao department, and i've seen too many hyper7 arms break to imagine that it would hold up okay to what I do.

excuse the long post

Hi, I have a 9.5 with a megatech 7 port i was wondering how it would run if i put some dominator wheels and tires on it. Would it handel just as good as the dominator or would it not have the correct suspension geometry. I know the megatech will be able to pull it around because it has tons of torque. So thats not a problem but would i need to change the geaing or anything.
Please tell me anything i should know


Thanks
James

[-=ADA$=-]

sorry to bother and to ask such a thing, but is it possible to get part # for the things needed to convert MBX R2 into PRO?? i dont know where to look, and what part to looks for.
Thanks in advance for help

[uDi_MP75]

Hey nitroice, don't post on both threads, it just makes it messy. My doing so was because I made a mistake... won't do it again. I think its a good idea to keep 9.5 questions in the 9.5 thread, and any other ofna buggy q's in this one.

Hi all,

I was wondering if this 1/8th scale buggy is worth buying. I am thinking of getting into full time Gas racing but dont have a huge budget to go out and buy the best. So, what are your thoughts on this $330 RTR buggy?

Thanks,

Dale.

[metal gear]

you should look into the Hot Bodies Lightning RTR or OFNA's Hyper 7s if you plan on racing

[-=ADA$=-]

what are the part # for diff shims?? i have old MBX and im affraid il stripe gears, or what gears should i get part # please!! thanks

[shift fast]

I need help putting a HPI .21BB into my mbx r2....

Has anyone done this?

[-=ADA$=-]

i didnt put that engine in, but whats the problem??

[shift fast]

Just the cluth nut that ofna supplies doesn't fit so I'm going to try a HPI one I guess?

[-=ADA$=-]

im using kyosho nut on hyper 8 port, and it works

[R3VoLuTiOn]

wuts everyones opinion on the ofna lx pro rtr
im really interested in this buggy.

im mainly a basher, dont intend to race..... is there a variety of replacement parts incase **** breaks?

shiftfast

hey shiftfast do you know what type of shaft is on that hpi motor? the hpi clutch nut should work but you just may have had the wrong ofna clutch nut.



R3VoLuTiOn

the lx pro is a good car for bashing and as long as OFNA keeps selling the LX MBX line then there will always be parts out there for them. two of the best site to get parts for them is www.nitrohouse.com and www.ace-hobbies.com they almost always have parts in for the ofna cars.

[R3VoLuTiOn]

wuts teh top speed of this lx pro.... verified plz :(

[morfracerX]

RCCA said 40 something but who cars about top speed in offroad.

[R3VoLuTiOn]

i do.. cause im gonna put on road tires on it and race with firends and etc...

[morfracerX]

Then whay not get an OFNA GTP?

[R3VoLuTiOn]

cause gtp cant go offroad and my budget is around 300

[morfracerX]

the the pro is the buggy for you!

[R3VoLuTiOn]

k so any 1/8 buggy tires and wheels should fit on this lx pro... correct? and wut glow plugs do i use. (im ordering ONLY from towerhobbies)

[morfracerX]

make sure you use that $15 off thing and hurry the 30th is coming up fast.

yes alsmost any 1/8 wheel/tire will fit on the buggy (as long as it's a 17mm hex style rim. now i would try an OS #8 plug i was just going threw the same problme trying to find a plkug for my new motor.

[mtrsprt]

RCCA is on crack. The LX Pro with .25 will be lucky if it hits actual 35 mph. A hyper 7 with the 8-port does around 38 mph bone stock.

[R3VoLuTiOn]

so the lx pro is a slow POS? my electric goes faster than that...

[mtrsprt]

My TC3 with Trinity P-94 8T double, does 34.8mph with a 7.2 6-cell, 38.2 7 cell, and 41.4 with my custom 8 cell.

you're jumping the gun there a bit bud. he is asking if the LX is a POS.

Now acording to the test that this MAG did a world class mag, they said it did 40+, noiw i don't know how you clocked your cars but i will stick by their words untill i see proof otherwise.

[mtrsprt]

morfracer, it was done with GPS, the most accurate measuring system yet.....

[PCC]

GPS is good at measuring a constant speed but you must maintain that speed for some distance to get a good reading. Its instantaneous readings are off by a few MPH as it averages things out.

[mtrsprt]

I had plenty of distance.

[R3VoLuTiOn]

so it does under 40mph with a .25 engine...... :eek:

[MBX4RR]

Does anybody have a Ofna Hyper .21? if so what kind of pipe do you use? i have a RB and the header is to close to the pullstarrt and keeps on melting it.:(

[ALJR]

comercial gps units have errors built in to them.. you will NEVER be exactly where they say you are or should be. this is dun for national security reasons! so it may be hard to get an accurate reading for speed...

[illbreakit]

OK, this may seem like a noob question, but what's the difference between the Ultra LX and the Ultra MBX? My LHS has teh LX in stock, and next friday, I am thinking on getting it. I am stepping up from myRC10GT. I do not race 1/8th, there really is no facility for that size for about 3 hr's drive. I prolly would race it against Maxx's at the club, but that would be unfair :D. I mostly want to BMX park bash, and run on the sand flat's by the river.

Thx for your help

[-=ADA$=-]

MBX has pivot ball suspension, and LX has c-hub, or king pin, thats main differance

[illbreakit]

OK cool, What is the first hopup I should be getting???? What do you hop up on these, they seem pretty hopped up as it is.

[illbreakit]

Update:

I finally got to the 6th tank and started leaning the .25 out. Everything waqs going good. I was at my lical BMX track(no water at RC track unless it's race day so it's to dusty) I blipped it off the first jump, ok cool. This thing has real nice air attitude, nose up, just a taqp of brake's to flatten it out. Well, 2 jump's later I land and the left tire is at a finky angle. It was a flat landing, just bounced a touch. The lower A arm ball joint pooped out . I'm like HMM, so then I pop it back in, try another jump, kinda nose down on that one. Wheel's all funky again. This time, it's half of the ball joint holder in the A arm is missing There is just enough to 'clip' the ball into it and have it hold on flat/small bumps.

Is this a comon problem???? Or did I get a bum arm??? I would have thought the LX style is stronger than the PBS style. PBS being the ball threads/shank being the weak point. The ball seemed to pop out a little to easily at first so I am hoping I got a bum set of arm's.

The error you're referring to is called SA which was turned off by the Clinton administration in August of 1998 to allow commercial GPS the higher level of accuracy needed by the navigational and transportation management programs being developed. We use GPS in the transit authority I work for to locate vehicles in emergency conditions so we developed our system to use DGPS (differential GPS). Once SA was turned off our system was as accurate as it was using DGPS but we continue to use DGPS as a redundancy system, however, it is not needed unless the government switches on SA in case of a National Security emergency.

I have been involved in ITS (Intelligent Transportation Society) for many years and can attest that many handheld, commercial GPS receivers are as accurate as you can get.

[illbreakit]

Gee, I get an Ofna Buggy, post in here and everyone stops posting. Did I scare everyone away?????? LOL

[morfracerX]

nah, i will just bee down for a while, i sold my xr3 bought a DOM (or two lol) and need to get it fixed up so i haven't posted much on the buggy thread.

iu have never had it pop out on me, you may have a bum arm. Has it given you anymore problems?

How has your buggy held up so far otherwise?

[-=ADA$=-]

i believe that pivot ball is stronger, and maybe the ball has flat spot on one side, and its connected wrongly?

[illbreakit]

morfracerX, Ya, I think it was a bum arm. I have abused the buggy at the BMX track since and nothing with the other arm. I still am gona get the PBS upgrade for it tho, once some more come availible. My ebay source is fresh out of them right now
As far as holding up, it seem's pretty good, I bent the front shock tower, tweeked acctualy from bad mandings from 30 ft :D That will get upgraded too. I took the pull start handle off and just use my box for starting, way nicer.

An official quote from the Ofna website is as follows:

"In California, registering a corporate name under 4 letters in length is nearly impossible. These letters were selected to form the corporate name, with no particular significance given to the name itself. Hence "OFNA" was born."

Straight from the horses mouth.

[-=ADA$=-]

i believe that you would need different shock towers, and body mounts, maybe wheels/tires, i think thats all (if shocks are same!)

[1 Bad STi]

I am considering getting a 1/8 ofna buddy RTR, which is the best bet?? Was looking at the 9.5 Violator? Is it out yet? I plan to run around my yard and hit the track sometimes. Thanks

l=like ADA said

Shock tower
body mounts
body
new tires/wheels
and depending on your buggy a center diff but thats not a must (IMHO unless you're really racing)

let me know if you need a parts list that lostbadracing guy gave me a kit to do it a while ago.

having a problem with my brake linkages hitting the tank on my ultra MBX, can anyone suggest a solution, thanks

[RC77]

Do any of yall know which is better for a begginer The Ultra MBX or the Ultra LX. this is my 1st car and i dont know which one to get. yalls help would be nice thanks.

[illbreakit]

By all mean's, get the MBX. The LX has some issues with it and that's why it's the cheaper of the 2. The suspension is fine on the LX from what I have seen(More like abused LOL) But the axle's are weak. The LX has 6mm axles and the MBX and all other model's have the tougher 8mm axles. This seem's like a small deal, but belive me, the 6mm axles bend just by looking at them wrong. No kiddin, I have bent mine just dropping it off my lap and onto the floor. You can upgrade the LX, but you need new hubs, axles, carriers and susp arm's so it's much cheaper to get hte MBX off the bat, cause that's what you will end up with in the long run.

[Combatcm]

I have an ofna purple flywheel on my force .25, along with that friction fit flywheel collar. Would it fit on the OS .21 RG? I want to put the RG on my buggy, but I don't know what parts I need.

[-=ADA$=-]

as far as i know if you have proper clutch nut ( for sg shaft, or threaded shaft) it will work

[chevyman007]

I have always wanted a 1/8 buggy. Ever since I saw how powerful and fast they are at the track. But over the summer I also saw how frustrating it can be to get them to run right, so I bought a B4 and mx-3 radio and started in electric racing. Now I think the big block buggies are calling me again, and I was looking into getting the ultra lx pro. It is 300 and I havent heard that many bad things about it. I will always bash with it and take it to the track everytime. So is this a good buggy? And since the force 25 is also used in the savage, do you think I could put the roto start on and use that instead of the pull start? Is there enough room to fit the dogbone through the towers and crank it up? Thanks for your help

[-=ADA$=-]

i think LX pro is nice buggy, the roto start should fit there, but im not sure about it, i think its great starter buggy, and if you have skills you would be quite competitive on the track ( but .25 is not race legal)

[kitty]

chevyman: if you can find an MBX Pro, I'd go with that over the LX. As for differences between the two, other than things others have mentioned so far, the MBX Pro comes with a kick-up chassis. Someone mentioned a page or so ago about the PBS on the MBX Pro. If you poof a little dusting of graphite between the balls and sockets, it'll do wonders.

I noticed the price you mentioned on the LX you are/were looking at. I'm guessing that's probably on fleaBay. One thing you have to watch for on there is people selling gray market or stolen stuff. I've asked a number of sellers if they are an authorised dealer, only one of which I've recevied a response from. You can call Ofna to see if the dealer you're considering buying from is on their list (or on their watch list).

I've even seen a few trying to pass off Ho Bao (the people who make the Ultras for Ofna) stuff as The Real Deal (though I've only seen a few). They are the same models, but you won't get warranty support on them.

I was seriously considering doing a "truggy" conversion on my MBX Pro, but I think I'm going to sell it and just buy a Dominator. If you're interested in it, feel free to PM me. I may put it up on the FS/FT forum first, then maybe eBay. It has about maybe five minutes rolling on the ground (just finishing up breaking in the engine) and has a new pull-start (high compression ate my last one heh).

ADA: The rotostart will work on the Force .26, which is what comes with the newer MBX Pros. There is now a different backplate you can buy (www.nitrohouse.com has them - much cheaper than those I've seen on fleaBay lately) on which the socket is lower. It supposedly makes it much easier to reach with the rotostart.

breakit: Geesh. I'm seeing you everywhere. Are you stalking me? :D Just kidding. Glad to see you over here!

kitty

[chevyman007]

It is actually on towerhobbies for 300:D
But thanks for the info. The lx does have a few degrees of kick up. I have the issue of RCCA that has the Lx and they say it has some kick up.

[ALJR]

the newer lx's now have the hard-anod chassis and threaded shocks.. but i would still recomend the ultra mbx...

i paid $309 shipped for my mbx pro :)

kitty.. get the savage. it takes allot of abuse and has decent power...

[illbreakit]

Kitty, I've been here for a long time. Just reciently got my LX tho, that's why you see me in the Ofna forum. I've worn Team Associated underwear for a long time now, feel's good to change once in a while LOL

I still have my other AE product's, but right now, the LX is just to much fun :D

[nitrothugg]

i dont know if this is a dumb question or not, but are any of the parts for the 9.5 or the H7 pro compatible?

[illbreakit]

no, it's ok. The 9.5 and H7 are made by different companies for Ofna. Ho-Bao and Hong Nor, not sure who makes which tho. But the will not cross over from what I understand. Uoy might luck out on some part's and be able to madify other's real easy, but without having both to compare the difference, I can't tell ya for sure.

[1 Bad STi]

you guys know if any pro-line bodies fit the mbx pro? thanks

[illbreakit]

Don't think they fit 'directly', but the croud pleaser should fut with redrilling of body post holes. The MBX has a rear body post like the hyper doesn't it, right on the rear shock tower?

[kitty]

Originally posted by illbreakit

Now there's an image I now wish to get out of my head :eek: hehehe

Re: 9.5 and H7 - the 9.5 is made by Hong Nor (same as the Ultra series, though no parts cross-fit there either) and the Hyper 7 is made by Ho Bao.

Re: Bodies. To my knowledge, and I've done a lot of checking around, no other bodies are a direct fit for the original Ofna bodies. However, from what I can tell, the Mugen MBX4 body may be a fairly close fit for the MBX Pro.

It's pretty relative to me anyway, because if a body can be made to fit, I'll do it. Body holes on other models won't line up perfectly, but that's what hole reamers are for, as well as body mounts taken from other vehicles. I'll be selling my MBX Pro soon, so I won't be tinkering around with retrofitting other bodies to it, but I'm thinking that if you can use the body mounts from other models it may help. I had to do some serious trimming on my MBX Pro body just to get the darned thing on my buggy and that's the stock body. It wasn't a big deal for me because I like to mod stuff anyway =)

<edit>
by ALJR: kitty.. get the savage. it takes allot of abuse and has decent power...
The Savage SS was on the top of my list, but now I'm pretty sure I'm going to get a Dominator and do the suspension mods on it. I can't remember what it was, but there was something that some Savage owners on another forum were saying about it that made me feel a Dom would be a better choice. I need to do more research again. Thanks for the input!
</edit>

[PCC]

Any body made for the MP7.5 should fit because the MP7.5 requires a larger body to fit over everything. I fitted a Pro-Line Crowd Pleazer body made for the MP7.5 onto my Ultra GT LX that was converted into a Worlds2.

[illbreakit]

I just got the PBS kit for my LX. Man, that's nice :D. I like it much better than the king pin just lookin at it. Has anyone had experience with this swap for setting's? Does anyone have a link to buggy handeling info? I run on a medium rough track with no challenging jumps whenI race, but when I bash it's at the BMX track so I hit big air there. Swapping setting's in no big deal for me, I just need to know where to start for each

Hey guys, I have a hyper .21 8 port and I was wondering what type of tuned pipe would be best to run on it?

What pipes are you guys running? Thanks.

[illbreakit]

Does anyone make stronger pivot ball's? I just converted my LX to the R2 suspension. Took to the track, halfway around, I land on the track edging off a 1 foot jump. Our edging is soft tubing. The darn lower ball broke off Not even half way around, what give's. Me is not impressed.


What is your take on the pivot ball susp??? It was cold out, but that should make the plastic weak, not the steel

[UltraSaiyjin]

damn shame, only my 2nd week running (no jumps yet) my Ultra Lx Pro and I now have a cracked front axle, take a look see. I wonder if ofna will replace with something better or send me the same weak axles.

there are stronger balls for MBX 4XR buggy and i believe they should fit, and i doubt that ofna will replace them, did they crack while jupming or just running?

[2mcgrath]

i just traded around and got a ofna ultra lx pro it is the newer version with the threaded shocks..just wondering what are some good upgrades to consider on this buggy..im allready having to replace the center diff and the ring gear in the rear didnt even get to run a tank out before all these stuff happened so that sucks..but what i got to run it it seems to run pretty good..also is it possiable to put monster truck wheels and tires on the buggy for a little more clearance in ruff rocky conditions..thanks

[illbreakit]

Yes, you can run Dominator tire's. I have seen pics of people's who have converted. The best upgrade for the LX is the MBX suspension upgrade. Search Ebay for "OFNA PBS CONVERSION KIT 8MM PIVOT MBX GT LX " That is what he list's it under. Here's a link to the kit picture http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3159490319&category=19168&rd=1

It has the 8MM axles, UltraSaiyjin, yuo will need these too if you want to stop bending axles. The LX has weak 6mm axles. They were made from crappy metal that's real soft. The reason you need the whole susp upgrade is that the axle carriers won't accept the bearings for the 8mm axles. The LX bearings are 6mmx13mm and the MBX's are 8mmx16mm. You also get way more adjustability with the PBS susp. The shocks will feel alot smoother and softer.

2mcgrath Make sure you get the hardened bevel gears too, there part # 31010

[2mcgrath]

yeah thats what stripped was the rear bevel gear and all the gears in the center diff was stripped..i noticed that about the axles mine had 3 bent ones when i got it..so i will look into the bigger axles and stuff..thanks for the advice on this

nice paint job on that body!

i was wondering what the top speed of the mbx rtr with the .25 would be around? i'm thinking about getting a 1/8 buggy, but i can't decide between the MBX or the XTM X-terminator...

[EvaderLXPro]

Hi im new to this forum i have an lx pro if u cant tell from the name. Anyways i would go with the mbx pro, i upgraded my lx into a mbx with the pbs it costs more the way i did it. I would think the mbx's top speed would be the same or near the lx pro's which is 46mph.

[EvaderLXPro]

is the roto start reliable i heard it breaks the one way bearing is this true?

[Combatcm]

I sense an evader trend here.

I GPS'd the top speed of my MBX with the .25 at 44.5 mph. I think the oneway breaks if you try to turn over a flooded engine. I bought one, but I don't think I'm going to use it. I'd keep the pull start.

[low10s]

what up ? i am interested in the violater can anyone give me some advice? thanks

[EvaderLXPro]

lol, evader trend. If you want to race i wouldnt go with the 9.5 violator its a good buggy otherwise. If you are gonna race id go with the 9.5 rtr or Hyper 7 PBS. I have the LX Pro and i do well against other 1/8th's I have beat some Inferno 7.5.

[low10s]

i looked at the lx pro, mbx pro and violater. i dont want to race it at the moment, that is why i have my xxx-ntDE. the violater kit just has everything i would need to get started. so what is bad about it?

[EvaderLXPro]

Nothing really bad i guess. It has the roto start and it may break the one way bearing. It cant be used for legal racing but unless your local track are sticklers for specs theyll probably let u race it.
It jumps really good. great motor too. and its hella durable!!

[low10s]

my track would not care if i wanted to race it. if i had the money i would get the hyper pcr, but that is too much buggy for my plans. the mbx pro or violater, hard decision. thanks for the info. about the bearing i did hear the only prob was if you tried to start it while the engine was loaded.

[EvaderLXPro]

Thats what i heard too. I tried to get one from my lhs but its almost like they didnt want me to get it. He said it would break the one way bearing. But then why does OFNA put them on the violator as a stock part. I dunno i might take the chance and try it out. If you get the violator let me know how the roto start works. I would go with the violator if i were you its so wide, man the handling on that thing has gotta be unbelievable!!!

[low10s]

thanks for the info, my decision is made. hopefully in 3 weeks i will have it. later

[-=ADA$=-]

as i know with roto start one way it sometimes can crack, but usually it just slips and thats all, cleaning is all you need to do to make it work

[Shawn300]

i dont remember where or when but i thought i heard that now the mbx pro and some other ofna buggies come with the force.26 instead of the old .25. Is that true cuz on websites that sell ofna stuff, and their site still say it has a .25.......:confused:

[EvaderLXPro]

Anyone hear convert their LX Pro to a PBS. I did with axles and all but the axles dont go into the drive cups too far. It works but i dont think its good for it to be on the edge of the drive cups from the front diff? I adjusted the Pivot balls inside the arms closer too!! Any suggestions? Also what size screw do I need for the Shocks to go on the lower suspension arms, all the screwz I have are a little too small.

[cucan]

Hi;
I am going to buy one of the 9.5 models but which one i cant decide between 9.5s rtr versions.Which one would u suggest?And which mail order company would u recommend.I cant buy it from tower 'cause thry dont send the 9.5s to europe due to the size restrictions.

[Combatcm]

Unscrew the drive cup set screw and extend it out as much as needed, put some washers behind it so dirt doesn't accumulate and it make the cup more rigid on the diff axle. Second, limit down travel as needed, change the shock position.

Nitrohouse is the official OFNA distributer. Check around google for stores in europe. There might not be any though.

Can anybody explain this? This is after around 15 tanks. Is it supposed to be that worn. It's a 16T savage clutch bell.

[EvaderLXPro]

Wow! I have no idea how that could happen. Maybe your gear mesh is too far apart or too close. I have not had any problems with mine doing that.

[Combatcm]

I set it so it has a tick of play, the closest I can get it without it starting to feel resistance when I roll it. It's a HPI savage bell, and I'm wondering if an OFNA hardened clutch bell is better.

[EvaderLXPro]

Why didnt you just keep the stock OFNA bell on it. If your lhs is helpful i would bring it to them and just see what the think they will let you know what size bell to get.

[monyet fangkeh]

hi...
im saving my money to get a mbx. i saw in my lhs, they has this ultra mbx rtr. i did my research and the mbx is the old version. its not the mbx pro. what is the diff between those 2? i know it might be better getting the mbx pro instead the mbx. but my lhs sell it really cheap right now.

also i really want to know if the ultra mbx has steel spur gear and i saw the pic at ofna.com, it looks like that the shock is threaded.

if i am getting the ultra mbx, what the first hop up to increase the handling or make the car more durable? i dont need eye candy stuff, im just gonna bash the hell out of it.:D

thank you very much

aryo

[EvaderLXPro]

Is it the rtr version or is it the 80% kit? I would go with the MBX Pro it has different engine. I think the chassis is different too. In the pro it has the kick up at the front and I heard someone say the 1st generation does not. If you have any more questions just ask.

[monyet fangkeh]

its the rtr one. but im not gonna use the the radio cos i've got my xs3 for that. i couldnt get any thing else. my only choice is the ultra mbx rtr or inferno mp7.5 sport. but im choosing the mbx cos its cheaper.

i want to know if the mbx has steel spur gear or not? cos if not, that is my first thing im gonna buy.

what is the front kick up do? is it gonna makes a big difference in handling or performance?

thank you
aryo

[EvaderLXPro]

Well it is cheaper for a reason. But the MBX is a good choice ask the hobby shop if it does. I am 99.9% sure it does because the only car I know of that does not is the Pirate 10 rtr which sucks the big one.

[EvaderLXPro]

How do you get images that are on my hard drive onto the forum?

[savagepicco26]

i'm interested in getting into 1/8th scale buggies. i have read through over 15 pages of this thread and don't understand most of it. i'm wanting to get a buggy strictly for racing. the local track here is very large and very fast. i have a Picco .26 Outlaw that is freshly broken in that can go in it and an Airtronics MX-3 for electronics. So basically i'd just need a kit. what would be the best kit for an all-out race buggy. i have my Savage for bashing, and some racing, but want a hardcore buggy for racing.

[EvaderLXPro]

depending on how much you want to spend. The hyper 7 kit by ofna would be the cheapest all out racer. Otherwise if money is no object go for the Kyosho Kanai Edition 3. The Hyper 7 is a great buggy and really durable and it has many hop-ups. I woudl probably go with the Hyper 7 kit of some sort.

I woudl probably go with the Hyper 7 kit of some sort. thanks for the reply. can the gearing and drive train on that handle the picco 26? from what i've read, the "7" buggies run .21's and the "9.5" buggies run .25/.26's, or am i reading wrong? seems most people run .21's at the local track, but i don't know if there's restrictions. don't want this picco to go to waste.

[EvaderLXPro]

It should bolt right in hte 7. The people at your track use .21's because that is the biggest race legal engine for buggies. Unless your track are sticklers for the rules you should have no problem putting it in a hyper 7 and racing with it. Talk to the track owners and see if they mind you running a .26 in a hyper 7. I also reccomend going to the hyper 7 forum on this site or at ofna.com. Lots of good info to be heard there.

[topher]

Just took delivery of my new 9.5 RTR.

http://home.cogeco.ca/~tophercannon/new.jpg

[-=ADA$=-]

it sure looks nice!! im currently upgrading my MBX trying, and trying ( ill try tomake custom made shock towers :D)

[topher]

Thanks, although I wish the kit came with an unpainted body.

Before the good weather hits I'd like to upgrade a couple of items. Firstly a high torque steering servo that's compatible with NiMH batteries and the supplied receiver. Secondly a trickle charger for a Team Orion Marathon NiMH 1200 hump pack. Nothing fancy just something cheap to charge the packs over night.

I found this charger over at Nitrohouse
http://www.nitrohouse.com/images/10010-19999/10214,-NiMH-battery-charger.jpg

Cheers.

[-=ADA$=-]

itll charge the batts in about 10 H so its a bit long, but i think itll do the job, i have hi-tec MG 645 servo and its swings these tires with no problem

[clemnc04]

:) I'm new to the forum but I have searched everywhere to try to find out witch is a better buggie. The 9.5 MBX RTR or the Hyper 7 PBS. I'm looking to purchase one or the other. If I could get some feedback it would be a little helpful, thanks.

[-=ADA$=-]

as i know H7 has more flexible parts, so it wont breake as much, but doesnt respond to input as quick, and 9.5 is opposite, less fleible, more respons, but will break easier ( which doesnt mean either of this will break easy!! its still great piece of a buggy)

[EvaderLXPro]

Well if it were me and I was lucky enough to have that kind of money to spend I would most definatly go with a Hyper 7 PCR. It is race ready out of the box. With a few other upgrades like new servo and maybe light shock tower and chassis braces it would be even better.

[Shawn300]

my pbs. I would prefer this over any other buggy. cant beat it for the price. they have great deals on them on ebay. I got mine NIB on ebay for 400.

[illbreakit]

The Savage has a Nylon spur gear I do belive. This would mean HPI can use a less hardened clutch bell. Less hardening mean's cheaper. Get a clutch bell for a 1/8 buggy. Be it Kyosho, Ofna, Hot Bodies etc. Pretty much all 1/8 have steel spur's so the matching bell's will be hardened for them.

[Combatcm]

I settled with a duratrax 17T one. Kind of high, but only makes the car top at 40 mph. That is with the standard hot bodies .21 engine. I think I might get a wasp .25 engine.

[Saboteur]

Hey all. Looking for a decent overall review of the Ofna MBX R2 80% with .21 compared to the Ofna Mbx pro with .25 rtr. It will be just for bashing around. Small jumping...nothing huge unless I decide to be a dare devil and stun the crowd at the HS. I hear the diffs are easy to bust but I wasn't there to witness that. From what I know, I've known and seen people running the old gt lx's and mbx's around with no problem.

[dutchalltheway]

ok guys..give your opinion to this newbie...
I'm totally in luv with the OFNA 9.5 but....which one to choose??
Can you guys help me out please??? :) I really like the violator..but the MBX is pruuttyy cool to... :p

[-=ADA$=-]

i think MBX is great if you have set up board, i have older buggy with MBX suspension, and its great pain to get it dialed in without setup board

[methodman]

Hi all,

got my Hyper 7 sport last week, just got it fully ran in...

so what hop ups would you all suggest?


rather fancy some purple or carbon shock towers, can find them on any site, got any links?

also those RB pipes look tasty, is there 3 types, one for low, one for mid and one for top end power?

and on the top options site there`s about 6/7 pipes and manifold options i`m getting confused

[scrisp2]

I just saw my first nitro buggy race yesterday and now want one of these as opposed to a monster truck. :D

I am a newbie, never had a nitro buggy before (or an electric, for that matter) and have been reading some of the forums and now have a couple of questions.

1. I've kinda narrowed my "want list" down to the Hyper 7 PBS and the Ultra MBX Comp. Which would be better for a new driver, and possibly my stepson to drive (He's 10 years old)? I'd like something as durable as possible, but something that can hold it's own with other buggies, on an indoor track with lots of jumps and a long straight away.

2. These are both 4WD right? They look like they are on the Ofna site, but it's hard to tell.

3. When looking at the motors, I see them listed as .21 and some others as .25. What do these numbers mean? I saw one that was a .25 motor, but was something like 4.1CC, so now I'm confused over what the number mean and what they correspond to.

I'm hoping to get my buggy in the next few weeks, as I just found this great track, about 15 miles from home, and there are lots of racers there to hang out with. :)

Thanks for the help,
Scott

[Saboteur]

Sounds good, but that buggy is old and won't be as tough as the newer Ofna's. The price isn't bad, but what condition is the car it? What servos is it coming with and check the condition on everything. The buggy is ok, but everything else sounds good.

[4rcphr33k]

I remember the servos being futaba's the car only had a few scratches..
I know the guy, he said he has NEVER full throttled the motor yet.

[Saboteur]

What Futaba servos are they? Do you have the numbers? Standard servos aren't worth much.

[4rcphr33k]

They where.. Futaba 9350

[Saboteur]

Naw, didn't find those. Sure the numbers are right? :confused:

[ron1431]

i want a buggy is the ultra lx comp good buggy to start off with. Can u put a roto start in it and what kind of upgrades do u need to get for some good bashing. thanks

[4rcphr33k]

any one have a ofna hyper TQ sport??

How do you like it?

[mdewitt71]

Just got a Ultra LX Comp buggy, was wondering if there were any Ultra 1/8th buggy owners out there.
I got mine and although I got rid of the cheap servos in it, I am liking it very much, pretty quick and built really durable....so far.
I would also like to see some tricked out Buggy bodies, kind of tired of the RTR bodies, ha ha.

I love my ultra I beat the hell out of it I have won several races against mugen mbx 5 /kyosho 777 and won!! What the manufactures don't want you to know that its all driver! an entry level ofna is just a good as a high end buggy!!at 1/4 the cost! I would upgrade to a 645 hitec for steering and get a failsafe and a throttle return spring! and go kick up some dirt! :D

[Ball Racing]

You can put a Mayhem body on a Ultra comp LX with a new hole for the body in the front, and a little cut for the battery box in the rear.

[mdewitt71]

What are some good tires to run on pavement for the Ultra buggies?
Anybody got the 2 speed kit option, How do you like it?
How about truck tires, anyone mount em on theirs?

[cullum1228]

I have a factory Ofna Violator (except for servo & radio upgrades). I have the force 26 engine tuned and running well. The only problem is it doesn't jump off the line well, it screams after it gets rolling a few feet. I am not sure how to tune the diffs on a buggy that has 3 diffs. I know how to tune them in a stadium truck so I am familiar with the process in general. I also have a big problem with bottoming out on jumps.

I have a few questions for you.

1. What weight diff. fluid should I use? Can/should the diffs. be adjusted like a stadium truck? Do you fill the diffs totally full of fluid?

2. Are the factory shocks any good or should I buy aftermarket? Can I simply rebuild them and if so what fluid should I use. I like to race on a home made track and do some jumping but nothing too extreme. Doesn't take too much to bottom out the factory shocks though.

Thanks guys!

[elkhorn98]

What does everyone think of the Hyper TQ Sport Kit? Is it the same as the Hyper 7 RTR or Hyper 7 Pro RTR? I have seen it listed both ways. I have seen it for $239. so for about $500 total I can get the kit, a decent radio, and engine. Thanks.

[RoadKill Racing]

I am going to pick up a 1/8 buggy. Just for fun, no sanctioned racing. I have my own track so anything I want to use is ok. I am looking at OFNA 1/8 RTR Ravager. Or the Ultra 95 MBX RTR. Both are the same price $350. Of the two with one should I get and why. Thanks

[mdbeachy]

I just got a 9.5 buggy, when I hit a small bump the front will go right over it but the back will kick up in the air, how do I fix that? Do I change oil in the shocks, go with diiferent springs, any help would be appreciated.

[WheelNut]

Roadkill- The Ravager is the newer design of the 2 buggies. The Ultra chassis has been around for over 10 years, the 9.5 (aka ravager) came out about 5-6 years ago I believe. Basically the 9.5 will handle better than the ultra, its just generally a better design. Not to mention the ravager will perfectly accept the pro-line crowd pleaser body which is way nicer looking than the stock lump :p Plus the Ravager has a bigger engine.

[Calden]

I'm looking for the ultimate basher buggy. There are so many OFNA's to choose from. It won't be raced, strickly bashed/sped/jumped etc. I'm power hungry hehe. I don't really have a budget... I'd like to get away with a setup around 500 but """IF""" it would be worth it I'd spend up to a grand. My lhs is a hobby town... i'm sure they carry OFNA... but I do most my shopping online as the hobby town is far away. (if there is another buggy brand that might work suggested it... pm or something) Thanks!

[flashprash65]

Hi guys i'm a newbie. I just bought a used Ofna Ultra GTP-2 and the gear 1& 2 in the transmission spin but the car does not move. I can throttle it up but nothing. with the engine off, i can manually spin gear 1 both ways, gear 2 spins freely one way and engages if i spin it the other way.

Can someone give me a clue if the gears are doing what they are supposed to? what can the problem be?
