Don't get any radio with driver assistance. Such as Spectrum AVC recivers. They don't play nice with the ESC that comes with the TT-02. Had it in one of my cars and I think it smokes the ESC and motors. Have another TT-02 with a Spectrum DX5R radio and a S6240Rx servo/reciver and it works great.

That should work. If you get into racing, I would get a DX5R. Think the new one is DX5pro. It has a faster response time then the one you got. You can go all out and get a Sanwa m12s, or the m17 they just came out with. The 2 things I look for when buying a radio is response time and expo option.

I cut the tamiya plug off and put 4mm bullet connecters on. Not sure what battery has a Tamiya connection. I'm sure you can get an adapter on ebay or local hobby shop for almost any battery.

So me and my buddy's just got into onroad racing,real grass roots but fun.
anyway as a big tamiya kit fan I bought a tt02 hoping all the others would follow suit.one did,but the rest of the guys flaked out and got the brushed traxxas rtr car.neat as it is I'm not a rtr guy.
issue is these things are smoking fast on lipo.I thought about just buying a traxxas esc and motor to even the playing field, but I can go brushless....maybe a 15.5.....but what pinion should I run and be safe with temps?14 16?
thanks guys.

If you buy the same motor.. your TT02 will be faster. You'll just need to match their FDR.

The factory esc will not pull a 12 turn 550.....I don't think so anyway.

Try it! worst case, you'll need to buy a $30 brushed ESC later. :-)

Has anyone tried a titan 550 12t on the tamiya esc?
hold on......ill try it and get back to ya....

The traxxas ratio is 9.49
I can get to that with a 19tooth pinion.....
ill run this thing hard on lipo and see what the esc says....

With that gear ratio, you should be fine.

you think just the 25 tooth pinion will keep up with the 4tec.....I tried the motor and with some mods it would work.but clapping the cover down,it wasn't happy.I pulled it out.
also Robinson pinion gears seem to be off from the tamiya mesh just a hair.had to put motor in 18 tooth holes to get proper mesh(cover off)
I literally done all this in 10 mind,ill mess with it more this evening and really see what the issue is with the motor fitment.
