Would the protoform 190mm camaro zl1 body work then. Does anyone know if the car comes with a servo or do i need to buy one? And for a while i plan on using the stock motor.

Thanks for all of the replies,
Kyle

I can't seem to find the steering set. Can someone post a link to it for me.
Thanks,
Kyle

Awesome tip Blue, thanks!

I don't think any of the TT02 kits, including the drift one, come with a servo unless you buy the ready to run models.

Link to the steering set:

Tamiya also make alloy steering components.

Apart from tires, springs/dampers are there any other parts you think improve steering/handling? Maybe' its a bit of a vague question... but hop ups wise?

I'm thinking if not... it really comes down to shaving off weight just like a real car?

It depends on what area you want to improve exactly. Work is busy at the moment but I have a big article nearly ready on how to make a race level TT02 and it breaks it down into several areas like steering, stability, drivetrain, gearing and weight etc.

I personally think a nice steering servo horn (not the kit one), better steering set-up (Either the Alloy or at least the low friction steering step screws), adjustible front turnbuckles, high speed gear set, Oil dampers and the rear toe in uprights will give you a nice car to drive at a club. There is more that you can do though.

Hi Qatmix. I've just purchased a TT-02 and have enjoyed reading this thread and gleaning valuable info.

You mention using rear toe in uprights. Do you mean #54549 Aluminium Rear Upright - 2.5 Degrees, or is there a cheaper plastic alternative?

Also, do you know how an existing wheel track width of approximately 175 - 178mm, when using 24mm rims / tyres, could be increased to something closer to 190mm. i.e. a solution to give an additional 6 - 7mm track width on each side? I wondering, from what I have read, would either:

#84209, Long Wheel Axle Univ Shaft - TT01
or
#53410, Universal Shaft - Long Wheel Axle

fit the TT-02 to give the extra width desired? Am I correct in assuming that #54477 Gearbox Joint for Universal Shaft (TT-02) would be required for both #84209 and #53410?

Hi, enjoy your tt02

Yep I do mean the aluminium ones. There are no plastic alternatives they are cheap if bought from HK or japan.

As to the width, the long axles will only work with thick plastic wheel hex's or special ones from square.

I have just used some 7mm clamp hex's and then some wheel spacers to widen the car. It's still not 190mm but it's closer.

I will get my article ready soon, the car is going well, and I have a nice little tip to modify the car for rear camber in that feature.

Yeah Racing also make some toe-in rear uprights that may be a little cheaper. Their design is closer to the original part which is attractive to me as it looks a little sturdier for rallying.
The Tamiya ones look a little more on-road race orientated.

You could also look for some wheels that have more offset to help get additional track width, not sure how many of them would be 24mm though as most seem to be 26mm but you could have a hunt around.

Thanks. Shafts in both #84209 and #53410 appear to have splines and corresponding splined hex wheel hubs. The best pictures I can find which appear to show this is are on the rcMart (for 84209) and the Tamiya Japan (for 53410) web sites. I assume additional hex wheel hubs wouldn’t be required?

Would a problem with just using thicker hex wheel hubs and spacers on the normal length of shaft not be that there would be insufficient thread left for the wheel nuts to lock on?

I enjoyed your previous articles and they were the main inspiration towards my purchase of a TT-02. Can’t wait to read your next one.

Thanks. I'll have a look at the Yeah Racing rear uprights. Unfortunatley I'm currently stuck with the 24mm wheels and the resultant approximate track width of 175/178mm as I have to use premounted/glued control tyres. Not a good look under a 190mm shell !!!

Does anyone know if a #51000 Hi-Torque Servo Saver would suit a TT-02? The distance between holes on part D10 from the kit appears to be approximately 21mm centre to centre, whereas it seems to be less on the Hi-Torque Servo Saver?

Also, would #54121 HT Servo Saver Alum Horn have the same distance centre of hole to centre of hole as part D10?

I bought the hi torque one and it was a pain to build because of the clips you put in there. I believe you would have to adjust it appropriately with your adjustable turnbuckle?

Qatmaix can answer this one :P I'm using the stock one and have not had issues plus my TT02 is used purely for off road and I've done maybe 30 cartwheels with it. I just got t boned last week so we will see. My low friction screws both snapped in their threads! New tub ordered

Hey ATG,

I use that servo saver on three TT02's. The fit is tight but not hard to do.
An adjustable turnbuckle is needed as DJ said.

After stripping a servo once before I now use these all the time - I haven't actually used the stock setup.

Unsure on the alloy piece.

Cheers,
Crouch

As mentioned, you can use a Hi-Torque servo save, I would recommend it over the std one. I like a 18mm horn on the servo saver, 3Racing make an alloy horn to fit onto the Tamiya Hi Torque which is 18mm high.

You can just use the plastic ones in the Hi-Torque kit, I would use the larger one (the one with 6 holes) and mount the turnbuckle on the top left and set that up to be straight. This is higher than the other setting and will give you all the throw you need.

I want to maybe gear higher at my track. Currently using 19/70 gear combo. Car tops out around half way on straight. Not sure if I should gear higher... If I want to get higher top should I get the 55/58 spur for the higher teeth tamiya AV pinions (20-25t)?
