OFNA CD3 PRO/RTR Thread v1.0

[1stGenCRXer]

Yeah, I've been doing pretty good.

That looks like it should be a speedy vehicle.

[BDavis]

well, I crashed the car pretty bad after beating up on a NTC with a nasty little .18 TZ The car was doing maybe 70+ MPH at 3/4 throttle and hit a bump or something and went straight into the air end over end over end over end and damaged both front and rear tires on the passenger side and I don't want to even repair it. I will purchase a brand new CD3 tomorrow morning and build that one just like this one. I lightened the chassis as well and that made a HUGE difference in the way the car handles. Oh well, time to get busy again.

"I'll be back"!

[1stGenCRXer]

Yikes, was that with your pro mod body on it?

I had some pretty nasty blowovers with my car using bodies with no side supports molded in at all. Learned my lesson, and now I don't even consider a body that doesn't have some form of side support.

Thinking of getting this one next, seen one in action and the downforce the body makes is crazy. Hard to see in this pic, but there's 3 molded ribs on each side. http://www.serpent.com/product/170111

[nitrohead5300]

Damn!!!!

[BDavis]

Well I just placed a order for my NEW CD3 for $209 from Nitrohouse. It will be here next Wednesday and I will then start to mod it to my specs.

Thanks guys for the condolences........lol.

1stGen, that is a nice looking car. Are you getting the body or the complete car?

[1stGenCRXer]

Definately not going to get an entire Serpent. Too expensive for the amount of racing my schedule allows, and zero local parts support. I will be getting one of those bodies though. From the way I saw it perform, it has as much, maybe more downforce than the Lola bodies I tried to run a few times. I could never get the aero balance quite right on the Lola's, but the balance on that East Civic body seems to be spot on.

I'm on a boat anchored off Galveston harbor right now for Gustav, so it'll be a while before I can get back to paint up a new body and race some more.

You picking up another Pro RTR, or Sport RTR? What kind of modding are you going to do?

[BDavis]

Good luck out there with that Hurricane. At least our government is trying to get the **** right this time.

I am going to use the chassis from the crashed CD-3 since it is already lightnened and it is straight.....no damage. I got the RTR for $209 from nitrohouse. If you go to ultimatehobbies.com, they sell the RTR version for $209 but stock status is "on order". I called nitrohouse to see if they would match the advertised price from ultimate and they did especially that I buy parts from there ALL the time. I will do this car just like the old one and use the old parts as spares. I've already taken the other car completely apart and will paint the chassis flat black once I get it sanded down. It should be pretty nasty AGAIN! I really have found a car that I really, really like and think highly of even though it doesn't get the recognition, for what I do with the car and the cost, it is PERFECT.

[BDavis]

Well the new CD3 came in and it is now time to build it up to what I had in the other chassis. As you can see, the stock chassis from Ofna has alot of room for lightening as I have already done with the original CD3. I hope to have it back running within a week or two because I have to make new CVD's since one of them got lost in the crash.

[1stGenCRXer]

You did a pretty good job on the cutouts it looks like. I can't bring myself to carve on my pro kit chassis though, lol.

[BDavis]

You did a pretty good job on the cutouts it looks like. I can't bring myself to carve on my pro kit chassis though, lol.

You got any pics of what the pro chassis looks like? It didn't take too long especially using a good blade in a sawzall. I then just painted it flat black.

If you know anyone looking for parts, I have lots of transmitters and recievers, three .12 motors, 2 new bodies and 2 sets of the honeycomb wheel/tires that I will let go for cheap.

[1stGenCRXer]

I might be interested in some of that stuff, but it's going to be a while before I get home and can really make a decision one way or the other. If I come accross anybody interested in the meantime I'll send them your way.

Does the RTR come with a Mega-R pipe, or a generic no-marking pipe?

And here's the closest picture I have to just a chassis shot.

[BDavis]

The pipes are the no marking ones. Just let me know and I will get out whatever part you are interested in.

The pro chassis definately looks different.

[1stGenCRXer]

Yeah, and the pro chassis has some relief milling on the bottom side too I think.

[BDavis]

Well it is almost completed. Just waiting to have the new dogbones made and then it is on again.

[nitrohead5300]

I like the boat pipe I hope it gives you the added boost you have been looking for.

[1stGenCRXer]

Hey man, why'd you pick such a small pipe? :p

Going with the pro-mod body again? If so, I hope you stiffened the sides up so you don't have another blowover, that last one looked pretty 'spensive.

[BDavis]

the blowover was WITHOUT the body on the car. Yes with that body, I wouldn't have destroyed the car as bad.

nitrohead, yeah I sure hope it works as well as it seems to be.

[1stGenCRXer]

Ah, I must've missed/forgotten that part. I know I've had some pretty wicked blowovers with some less than ideal bodies catching air, but never had the kind of damage your last car did.

Keep us updated.

[BDavis]

Well I am still waiting for the dogbones at the moment but for now, the car is in the state that you see above and is ready to go otherwise. How about you guys' cars?

[1stGenCRXer]

I just got back home yesterday, so any picture requests you have for a CD3 Pro kit I can get.

My car is ready to go, so won't be doing a lot of wrenching on it.

[nitrohead5300]

I am just finishing up my V-1RRR onroad so I will be giving it the shake down to see how she handle with the .18TZ on it.

[BDavis]

man take as many pics as you want and post up. I'd like to see the chassis specifically.

nitrohead, my man! you are "EVERYWHERE" man.......lol. Hey at least we keep the same screen names on the different boards. I bet that V-1RRR would catch pure h3ll agains the big block NTC3 though.

[nitrohead5300]

It would right now because the V-1RRR only has a OS .18TZ the NTC-3 has a .28 . I believe in a landspeed attemp race the TC-3 would beat the V-1RRR. However on a road course the out come may be different. Both cars handle great but the V-1RRR seems to react faster and seems a little more planted in the turns. I like the feel of the V-1RRR there maybe a big block in the future waiting for it.

[nitrohead5300]

Brent your car looks like it is going 100miles per hour standing still.

[1stGenCRXer]

I got some pictures, but it's going to be after the weekend before I can post them.

[nitrohead5300]

Brent if you are looking for another project car the V-1RRR would be a good candiate. I was saving your tires but it looks like I am going to have to use them on the V-1RRR. The .18 tz is more powerful than I believed it would be I am going to need wider tires and a wing to get enough traction for the rear end.

[BDavis]

you got any pics of the V-1RRR? I'd like to see some pics of the rear end where the motor sits and the 2-speed gears to see if I can do my big tire mod to it. How much is that car too.

BTW, you can get the CD3 from nitrohouse for $209 but only by telling them that ultimatehobbies sells it for that $209 price.

[nitrohead5300]

Brent here is a picture of Ziggy's V1RRR with a .28 http://i377.photobucket.com/albums/oo215/nitrolhead5300/untitled.jpg

[nitrohead5300]

Brent I believe that Ziggy said he had to make a extra long rear layshaft to get clearance for the side pulley back by the motor.

[BDavis]

Well from the looks of it, I can't do what I wanna do to the V-1RRR. I am just greedy using the large 1/8th scale tires now. I am not one for superior handling of the Kyosho's and Mugen cars therefore the CD3, NTC3 or LD3 cars seem to fit my kind of craving since I'm a straight line kinda guy. Don't get me wrong though, the CD3 does handle good to me for the kind of running that I do with it though. Definately keep me posted on your V-1RRR with the .18 TZ on it.

BTW, did Ziggy say how fast he got the V-1RRR to run with the Picco .28 on it?

[nitrohead5300]

Ziggy has not finished it yet. And I like my 1/8 scale tires too I think I can get the pair you gave me on but I am going to have to reduce their width by a few mm. If I go with a .21 on the V1RRR I know I am going to have to use 1/8 scale tires.

[BDavis]

Man you may have to use the big tires even with the .18 TZ on it. That engine is a strong mill. Looking at some of videos that Ziggy has, there was a P3 on a car that ran 100 MPH.

[nitrohead5300]

Ziggy is in the process of rechecking his speeds due to possible equipment error. Speeds maybe 10miles off. This winter I am going to try to make a vacuum forming machine so I can make my own extra wide bodies so we can use as wide a tire as we need.

[nitrohead5300]

Brent you know that Ziggy had his landspeed attemp contest last week?? The best somebody did with a Schumacher was 86 miles an hour then he crashed it. Then another guy with a Schumacher .28 did 75mph. That big fat belt is creating toooooooo much drag . The GTR which is a larger fusion did the best with 86 miles per hour but was unable to back it up. I think I am going to retired my Fusions to the shelf.

[nitrohead5300]

Man you may have to use the big tires even with the .18 TZ on it. That engine is a strong mill. Looking at some of videos that Ziggy has, there was a P3 on a car that ran 100 MPH.............You are right Brent the V1RRR has explosive acceleration !! I guess the centax is the cause of that .:D

[BDavis]

man I tell you, the belt cars definately seem like they don't roll as good as my shaft el cheapo NTC3 or CD3 does. I could sit my NTC3 or CD3 on a slight hill and they would just roll to the bottom with no problems but my friend has a Mugen MTX-4 and it would move about 2 feet before it would stop. I mean, Nic Case has been the fastest that I know of and there's another guy running a TC3 that has ran 135 MPH with shaft cars but of course belt guys will plead their case. You got a site for that top speed event?

[nitrohead5300]

I think for Drag Racing that the shaft car is superior because it has little if any roll resistance and very little power loss. But sometimes this can work against you in a road race the belt car gives you a little slip before the belt grips this little delay can actually help you thru the turns by gradually putting the power down with shaft driven cars bam!! 100% power if the surface is slippery you are going to spin out. This problem is amplfied by the skinny tires they put on the 1/10 scale cars too. Ziggy link http://www.fast-rc.co.uk/forum/index.php

[1stGenCRXer]

Here's the pictures I promised of the Pro kit chassis as well as some of the added adjustments the carbon bits give you.

As for setup, you guys are just noticing how nasty the 18tz can really be? ;):p

I have some pretty agressive setups that work well on the CD3 for straightline or road course racing with regular sedan foams. The CD3 seems to be very sensitive to rear toe angle, and it doesn't take much more rear toe to tighten the car up, once you find a good neutral point. And of course, once you've found the neutral point, taking away some rear toe adds tons of steering. I haven't found the car to be overly sensitive to sway bar angles, caster or front toe changes. They do work, but they don't have a dramatic effect. Just about all of my adjustments happen to the rear end now: rear toe, ride height and camber angle.

Anyways, on to the pictures.
Some chassis shots, floating rear body mount [you want this for speed runs Brent], with the carbon suspension mount, a shot of the rebuildable CVD axles, and a centax peaking out with the 0.8mod gearing.

[nitrohead5300]

Like the floating rear end.

[1stGenCRXer]

I like it too, made a huge difference in aero balance at all speeds, for the better. Body on the car handles like a TC should, body off, you know it's a TZ :p

[nitrohead5300]

Looks like a real durable car. Nice

[BDavis]

Where can I get the floating rear body mounts? What biggest benefit that my car would gain from one of these?

[1stGenCRXer]

Nitrohouse has them, it's a CD3/LD3 option part. You do have to use the carbon suspension arm mount at least on the rear though.

The biggest advantage is your body attitude stays consistent regardless of throttle input, so your wing angle of attack stays where you want it. Also, at speed all the downforce you can generate goes to the tires, not the chassis, so you don't have to run a heavy spring in the rear or jack up the ride height like a monster truck just to keep the chassis from scraping the ground.

With a floating rear body mount the car looks like you're driving on a perfectly smooth surface even though the suspension is still doing it job. Only the front suspension compression and rebound changes the body's distance from the pavement, and that's only the nose, forward of the front wheel centerline.

[BDavis]

1stGen, man I CANNOT find the floater mounts to save my life. Yes I see the carbon shock towers but not the body mounts. Can you provide a link?

[1stGenCRXer]

Here you go (http://www.nitrohouse.com/catalog/advanced_search_result.php?osCsid=c5cef3c79d86bba2 7cd93ba6912ff5c4&keywords=Floating&categories_id=89&inc_subcat=1&manufacturers_id=11&pfrom=&pto=&dfrom=&dto=&x=37&y=6)

OFNA part # 38603

[BDavis]

Here you go

LOL. I was looking for a picture the whole time:roll2:.

Thanks for the link and the part is now on order.........of course with other items as well.

[1stGenCRXer]

of course with other items as well.

Of course ;)

If your aero balance is anywhere close to what you need for that big block, you'll notice an immediate improvement with that floating body mount. I'll never run another car that doesn't have it as an option now. :cool:

[1stGenCRXer]

Get your floating body mount yet?

I just finished tweaking on my car for the final "official" parking lot race for the year. Raised the rear ride height a bit to cut down on grinding and trimmed up a new body for the mains.

I think after this race, the 18tz is being retired from the CD3 and put on my Revo, and I'll get a "legal" 12tz. I'm not racing on big enough tracks to need the 18, and the outlaw turnout is non-exsistent, so it'll just save me from having to cut a clearance hole for the cooling head going with the shorter 12tz.

Something I'm mulling over doing in the off season. This winter is going to be all electric.

So, wish me luck Saturday, going to be racing 3 of the 5 classes, lol. Nitro Sedan, Recoil 1/14 Sedan, and Legends 1/10 Oval.

[BDavis]

Yeah good luck man. Unfortunately the floating mounts did not work out since I have the bigger tires on the car and the rear control arms being narrowed, the upper mount won't connect to the wheel hub.

Good luck out there too man and hope you bring home a big win for the Ofna CD3.

[nitrohead5300]

Hey Brent have you finished your Pro Stock Dragster yet??

[1stGenCRXer]

Oh man, that sucks!

Getting ready to leave the house to go race now, report to follow.

[1stGenCRXer]

Nitro turnout was real low, I was TQ with my best run all season, but the rest of the field had a lot of catastrophic failures trying to keep up [including a NTC3 that is now a motorcycle], so we didn't run mains.

My recoil kept hanging brushes on the motor, so even though the car was fast, I didn't get the results I wanted. I'm going to take a spare with me offshore next week to work over with some harder brushes and make that a non-issue.

I did win the very frantic fall-series opening Legends race though. Didn't do very well in the qualifiers, but I took a gamble and zip tied my solder spool directly over the motor and that seemed to settle the car right out :D Now I just need to weigh the spool so I know how much stick on weight to add so it's not quite so ghetto, lol.

It was a pretty cool day as well, so even though my CD3 was running well, the tires never really gripped like they had all summer.

The 18TZ has been removed and is now installed on my Revo, so the CD3 is sitting naked until I pick up a 12TZ for it. I liked the speed and torque of the 18tz, but I never really used all the power available when racing, so it's time to dial it back to something a bit more sensible.

[nitrohead5300]

Sounds like you had a interesting day!!

Still looks mean.

Even though I can't imagine ever doing it myself, what parts did you use to run the 1/8th scale foams?

More pictures of how they mount would be good too ;)

I'll be posting pre-season pictures when I get mine all cleaned up and I pick up a shiney new 12TZ.

Does That Crazy Wing Work Or Just For Looks

Also Looks Like Wolfpack Adapters On The Wheels.

[BDavis]

Does That Crazy Wing Work Or Just For Looks

Toad, the wing is just for that pro-stock look. I hated the high rise wing that came with the car so I cut the molded wing bosses off and made the wing you see and yes those are the wolfpackradicals wheel adapters. 1stgen, I will take more pics later for you.

BTW, I now own 4 CD3's since amainhobbies was selling them for $159

one of them now uses a .12 JLR Picco red dot modded.
one of them will have a .18 TZ modded as well.
one of them is bone stock for my 11 year old son to get used to and then I will install a RB .15 modded as well for that one

[1stGenCRXer]

Be sure to get some body-on 132' video when you start running ;)

I just put my on-road engine on order, so my car will be going back together as the weather warms up. Been playing with an electric TC indoor on carpet this winter, so the CD3 has taken the back-burner until I get an engine back in it.

[O_ROD]

Hey guys, just bought a used Ofna CD3 RTR and had a question. How did you fit all the servo wiring/fail safe/batteries/receiver into that small compartment? Seems like it'll take an act of God to shove it all in there :huh: pics would be much appreciated. Thanks! :wave:

[1stGenCRXer]

I can get you pics later this week. The RTR radio box is eaaaasy to get all the wire in ;)

I'll take pics of the Pro RTR radio box as well as my Pro kit radio box. There's a reason boxes have lids, lol.

Having a small receiver helps a ton as well, but it's mainly patience, planning and zip ties.

Thanks a lot. The car didn't come with the stock receiver or battery holder, I had to get my own. I can only assume the ones I got are bigger than stock because I've tried many different ways to fit is all in there. :rolleyes: Hard to tell where everything goes without seeing the stock set-up. I'm using a Cen Racing receiver larger than stock battery holder :o

[1stGenCRXer]

Ooooh... you may need to upgrade my friend.

Currently, the Pro RTR has a JR FM system, and my Pro kit has Spektrum [original 3 channel receiver from a few years ago].

I also use a flat receiver pack in the Pro RTR, which helps open up a bit of room.

Like I said, I get back home Wednesday, I'll try to get you some pictures up by Thursday.

[O_ROD]

Hey, I've since made some progress with the CD3 and ran it today for the first time. I ended up taking apart an old Hi-tec receiver and placing it in the receiver box with no cover. Everything fit great.

Car was a lot of fun, until I took a corner too fast (30mph) and veered off the road doing multiple flips. Ended up cracking the front hub. Oh well, have to rework the electronics too, I started to lose battery on the receiver and the car had a mind of it's own for several seconds.

Also, the car at idle wouldn't stay stopped, it went forward at a good pace. I'm assuming the clutches need to be adjusted? Can anyone verify? Thanks.

[1stGenCRXer]

Glad you found a way to get everything fit and run the car. Had to be a pretty hard hit to break the front hub. I have spares, but have yet to need one.

Is the idle too high? Usually if the clutch spring(s) are broke, the engine will die when the car is stopped.

Sorry I haven't gotten you any pictures yet, I've been scrambling around pretty good to get my car ready to run at 301 raceway in Maryland tomorrow, and just now found time to take a break, but of course now the car is loaded up ready to head out in the morning.

Let me know if you still need those pictures, but generally you just have to "make it fit".

I think I got everything sorted out in the battery box. Had to do some remodeling on the receiver but everything fits great.

I checked the clutch and the springs seem fine, the force .12 spring set-up is a lot different than the single spring I'm used to. The clutch pads look like new as well. I completely dis assembled the 2 speed and re adjusted everything. Is there a screw that affects idle? I have the throttle body closed as much as possible in the idle position but it still seems high. Thankls again for all your help, I can't wait to get this thing back to 100%
