The DT02 is not able to change the gearing other than the 17T or 19T pinion changes.

You can still have fun with them, and there are special DT02 only races.

Here is an article about all of the modifications you can do to it.

then i have to change the motor because the pinion gear is to 19T limited, right?
now i have ESC TBLE-02S from tamiya and i run RS 540 Sport tuned from tamiya also.
Can you recommend a better brush and brushless motor. The ESC limit are 25T for brush motor.

Thx a lot guys....

The key to the DT02 is to find the right motor for the limited gearing. I've found that brushed motors get too hot (even with cutting the rear of the gear box away for added cooling). I recommend you try a 13.5T brushless motor. It will give you a nice amount of zip and run cool.

thx for your answers guys,

i just happen to know that the ESC TBLE02s is compatible with TBLM02s 10,5T 12,5T 14,5T and 16,5T. i don't have really any experience to brushless motor, its new to me, is that mean the lower turn has more speed and the higher turn has more torque? And can I drive without sensor cable even if its a sensored motor?I have Tamiya DT02
Maybe you guys can recommend any from that

Thx a lot.......

You don't have to use the Tamiya brushless motors. You can use any brand, so long as it's a sensored motor. And yes, you do need to use the sensor wire. If you're on a budget Hobby King sells the Trackstar line of motors for about $35. The lower the turn number, the faster the motor is.

Hello guys, I have 2 DT-02s, well, my kids have them, (see my old posthttp://www.rctech.net/forum/electric...-year-old.html) and i got a 3rd chassis for me to play with them.

I was looking at the gears myself, and i started to think of replacing the spur gear and shaft, but found this gem!

" Fig7: A counter-gear consists of three parts. TA05's aluminum spur gear holder, stainless 16T gear and TRF415MS's shaft."

Spur Gear Holder ideas
Tamiya 13455870 - TA05 Spur gear holder - i think this is only for the TRF415 shaft
Tamiya (#54234) FF-03 Alum. Spur Gear Mount - i can't see if it's a set screw or a shaft that holds it?

I think the "Tamiya 54500 TT02 High Speed gear set" - looks to have the correct shaft size for the stock shaft?

Pinion
Tamiya (#50354) 16T, 17T AV Pinion Gear Set - i think it's been drilled to have a larger diameter inside


Shaft
Tamiya TRF415 Center Shaft SP-1057 part# 51057


Anyone else have ideas?

As for the pinion to spur mesh, it's an easy solution, i slotted the holes so i can move the motor a bit

I have more modifications coming for my DT-02

The rear suspension arms, and hubs from the DF-03 will be installed, to replace the brittle DT-02 parts, and to extend the suspension arm geometry.

I found these pics



I am looking for a shaft that will work with the gearbox so i can install a Spur gear to play with the ratios. I have the lightweight DT-03 gear shafts that are 5x45, and hollow, but is there a 5mm outside diameter, and 3 mm inside diameter bearing?

Also planning on extending the wheelbase by 10mm with carbon fiber parts on the front of the car.

If anyone is asking why bother, well, why not? lol

Another option for the rear hubs would be the Tamiya TT02 Aluminum Rear Upright 2.5 Degree #54549, they have a 3mm hole at the bottom
