Sorry if this has been asked before, but is there a list of parts that are compatible with both the TT-01 and TT-02? I am gathering parts to rebuild my TT-01 and keep running across more TT-02 parts than anything else.

Very little, if any parts are interchangeable between these two kits. Tires, rims, wheel hexes, shocks, motor, pinion gear, bearings/bushings, maybe the dogbones.

Awesome, thanks for the help! I figured it probably wouldn't work but thought I'd ask.

the TT-01 has been around for ages and there is an almost unlimited amount of upgrades out there. There are even several chassis upgrades for the car. You still end up with a slow TT-01, but just one that costs three times the original price.

Yeah, I just bought the full Yeah Racing aluminum upgrade kit for it. I know it's a ton of money to sink into an old floppy chassis, but the TT-01 was my first RC car and I want to rebuild it into a shelf queen.

The Super Stock motors are a step up from the torque tuned or sport tuned, I was pleasantly surprised when i put one in a Top Force as I liked the look of the brushed motor in an older car. You may run into problems with the TBLE-02S though, it overheated in my Top Force so I switched to a HW1060. If you have the TBLE-02S then look at a cheap 13.5T brushless motor instead, performance is similar but the ESC can handle it and it has the bonus of no brushes that wear and need replacing.

The big advantage of the high speed gearset is you can change to 48p gears which are easier to get. If you get an adjustable motor mount as well (yeah racing make one) you can then get any gear ratio you want, so it is a good upgrade.

Personally my TT02 get bearings and I run them as is. Mine all came with oil shocks, I would probably buy oil filled dampers if they didnt come with them in the kit, otherwise they are good to go. No point in spending heaps on them

Very informative, thank you!

I've got the supplied TBLE-02S ESC so may look at some 13.5T Brushless motors instead.
Would I need any special battery to run a brushless motor, or would my standard 3000mAh NiHM battery be ok?

Also, If I'm just using it for fun, is there really any benefit to me adjusting all the gear ratios?

I've been looking at oil shocks too as I reckon that should improve the handling quite a bit.
Not sure if I should get the standard 55mm ones or bigger though, as not sure if larger ones would fit properly.

My way to go with a TT-02 "just for fun" :

- Ball bearings all around
- high torque Servo Saver (Tamiya 51000 for example)
- TBLE-02S with brushed motor (torque tuned, sport tuned, Carson Cup machine or similar)
​​​​​- high speed gear set with 64 t spur and 29 t pinion for decent speed
- oil shocks (Tamiya CVA or Yeah racing 55mm) for better control
- maybe the blue aluminum center drive shaft (just because it looks cool)
- a radio set with adjustable End points for steering is useful to go easy on servo and servo saver. Tt-02 does not need much servo movement for max. Steering angle. If you don't limit servo movement, you can kill either servo or saver.
- no need to go for the fastest and strongest Servo.
Someting with 0.1-0.15 sec / 60deg and about 5-10 kg torque is more than sufficient.

Doing so, costs are limited and fun/ durability accordingly maximized 😁

Thanks buddy.

I've got a Radient RS-HT201 6.5kg servo which does quite well, and have adjusted the end points on my radio too, to prevent damage to it
So I'm going to look into buying a new motor, high speed gear set and oil shocks.

It definitely needs to be faster, the torque tuned Tamiya motor just lacks some punch.

Torque tuned motor is plenty capable and has plenty of torque. If you pick up the yeah racing motor mount, high speed gear set, 64 pitch gears (say 78/48) and bring the final drove ratio down to 4, you will notice the Toque tune is plenty fast!

I’m building up my TT02 as a rally spec car for use on a fairly bumpy buggy track, I notice tamiya sell the Super Mini CVAs and the Mini CVAs. Does anybody know if the Minis will fit? I’d like to get the bigger shocks on if possible.

Or, if they won’t, is there a taller shock tower available, tamiya or third party?

fdr of 4 on a torque tuned will kill it in one or two batteries. I killed 3 of them in one race day and that was at 4.2. The car went like a rocket but got way too hot and demagnetized the motor. This is also on road with a properly shimmed and smooth drivetrain. Off road will probably be worse. I’ve found the sweet spot with the torque tuned for speed and longevity is with the 64t spur and 28t pinion both in stock gear pitch. Puts you at 5.9 fdr.

Outdoors, loose diffs, it's a preference thing but I always ran ceramic grease in mine.

What is more important is shock travel. The suspension cannot articulate more than the Super Mini CVAs, and if you needed it to have more down travel, you can always put on the longer shock eyelet ends.

Also, just today I finally decided to remove the little plastic bump on the lower a-arm that stops the suspensions downward travel. Removing it increased it the perfect amount! I originally thought about cutting the lower bump off the upright, but I'm glad I went this route instead.

HI,
I just built a stock TT-02RR. I got the newest Protoform C8 Corvette body for it. The wheels are too narrow for the body, but it works okay.
Is there a way to make the track wider? I was trying to find off-set wheels but came up with nothing.

Does the TT-02SR have a wider stance?

Has anyone noticed how hard it is getting to find RC car stuff?
