Install the sealed gear diffs with 2-5K oil in the rear and the other ones with spool like behaviour filling in front.

Hi guys,


So I've got my standard TT-02 car which has been set up as a rally spec, and all I've done so far is install ball bearings, which made a lovely difference.

I want some more speed now though and I'm not sure exactly what parts I'll NEED to achieve this (bearing in mind I'm a proper newb with this stuff)


This is what I'm looking at so far:


22T Pinion

High Speed Gear Set

Tamiya Super Stock BZ, RZ or TZ motor (not sure which one is best)


Would I need to buy anything else or would the above be ok for now and plug and play without anything else?


Also, this is used just for fun only, nothing competitive or anything like that.

Have some nice woods around my area and just want to thrash though them.


Thanks guys

The kit supplied pinion should already be the 22T, so if you want a bit more speed and don't want to change the stock 70T spur gear then go up to a 23T, 24T or 25T.

The Torque Tuned motors are quite decent and I tried the black Sport motors as well as a lightly tuned Lightly Tuned 28T motor with replaceable brushes and really didn't notice any difference.

Maybe best to get tires with better grip for dirt rally use.

Thanks Steve!

I’ll drop the pinion then.
Still think the high speed gear set is worth is though, that’s 68T I believe.

I believe the high speed gear set gets you a blue alloy shaft and spur gear adapter that lets you use more traditional spur gears.

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!
