Thanks. I am waiting to receive the Yeah Racing adjustable rear upper links and the 3 degree rear blue alloy hubs now to complete the package. I have a 25.5 brushless motor coming as well and plan to swap out the Team Powers 21.5 when it arrives.

It was an experiment and I will run it to see what happens.

Yup. That's the one. Dremel or exacto knife and I couldn't get it to fit. Got it close but it always snapped once tightened down.

Mind if I ask which areas you trimmed to get a better fit? I printed mine in PLA, for the area it shouldn't be an issue with heat except where it's close to the motor. Yours looks like PETG, and the printer could use some retraction setting tuning to clean up the print.

Ignore the crack. Took a good bit of force to crack. After it broke upon installation, I figured a proper stress test was in order. 100% infill with glow in the dark filament.

Rallye TT02 Tommi Mak edition EVO
 
Man this thing has some miles on it already LOL.
This is an eBay 13.5T adjustable timing no name brushless with the TBLE-04s ESC and a Surpass Hobbies low-pro metal gear servo. 30/64 48p gearing, locked rear diff open front diff.
Got spare rims and rally blocks cause running the 4000kv brushless setup at 40+mph in the dirt is a terrible, fun idea LOL. 13.5T on 2s is much more enjoyable in the dirt, 25-30mph depending on timing.
Removed the gyro for a more "authentic" rally experience, and put the FGR4 Rx in so I could use the super low latency NB4 for better control. It drives better with toned down steering and throttle mixes.

Came across Tamiya 22023 chassis cover set and jumped on it like flies on, well this is a family forum, use your imagination lol.

This is the chassis cover with the partial front wheel well, so a pretty good starting point for a full rally cover with ducting and screens for airflow.

Going to be picking up the 1992 Audi TT02 kit for the drift build( got the 1991 Audi for the rally/drift build), because now I'm doing dedicated chassis being I picked up Tamiya 51543 911 Carrera RSR and it's a short wheelbase body. Now looking to find Tamiya 84399 tall 911 wing to go with the body but not having much luck there. Going for GM Tuxedo Black from a few years of classic Corvettes. Deepest Darkest Blue I have ever seen. Doing the side panels by the wheel wells in carbon fiber vinyl and a few other things.

My cover was printed with PETG by a chap I found online offering 3D printing services. I paid $10 CAN to have him do this one piece for me. All 4 holes needed to be opened and I used a small file for that and checked often to make sure the self-tapping screws fit easily. The rear of the cover needed the radius enlarged a bit for a better fit, and the arc front and rear were very rough and I smoother those with my Dremel and a sanding wheel. The recessed mounting hole on the right rear did not line up with the chassis and I had to enlarge that one recess substantially before it would tighten down. The part isn't a substantial structural piece, but it does hold the bearing for the rear shaft so that is where I did my best to make sure the bearing held firmly. There was lots of fluff and thin hairs inside and out that I scraped away with an Xacto chisel blade.

Appreciate the speedy response!
I may try to print another. Since everything is close, I may try to scale up a hair or two to see if it makes any difference. I'll try to remember to get a pic of it fresh off the printer. There is a good amount of cleaning up the part when printing with support and such.

I've been printing primarily in PLA, But will be grabbing some PETG soon, And am going to get into designing stuff as well. I have a few one-off pieces I'd like to make.

The last of my chassis upgrades arrived today and were quickly installed. I am now waiting to receive my 25.5 brushless motor to finalize the setup. The tires will be replaced with a set of Gravity RC USGT tires if I can find some, and the ones I installed are vintage tires and rims from my TC3. I think that the white & blue contrast looks good.

Man I wouldn't mind a white chassis at all lol.

So I've got the 911 Carrera RSR 251mm body. I'm wanting to do a drift build but want to keep it kind of like a real 911 with the motor in the back. Was looking at the DT02 but looks to be far too much to convert.

What other RWD rear motor mounted chassis did Tamiya have? Want to steer clear of the M-chassis as I would like to be able to swap wheels between this chassis and the TT02s. Also I feel like front steering angles would be better without the front diff area left from converting a TT to RWD.

TA03R, don't run anything in the front gearbox and remove the belt. Technically mid motor, but I think it's the closest thing you'll find to a rear motor Tamiya TC. You can use the rerelease TA03RS Porsche 911 GT1 and find the longer TA03R chassis if you want new.

JJ100179 12-12-2021 01:13 AM

What about F103GT?
With a little bit of tinkering you might be able to reduce the wheelbase to 251mm.

MF-01X, and here is an example with Touring Car wheels on it...no issues.

Your best bet is a non Tamiya, one of those drift machines or this one from MST

Merry Christmas guys and gals!
 
Threw together a little Christmas drift video (more of a power sliding video as this is the AWD chassis).
Hope you all enjoy!
Merry Christmas, Happy Holidays, whichever you prefer!

Hi all, I’m building a TT02 from spares for display purposes. Will not be a runner. I have everything I need except the white nylon bearings. I looked all through my stash even for bad bearings and came up dry.

I need 8 of the 10x5s.. please PM me if you have them in your parts box

The stock white plastic bushings? I am sure I have some....LMK
