Hello I have an Xray m18 on the way I have been wanting to get an onroad car for a while but did not want the micro RS4(Prefer Shaft drive). So my wife and son bought me one for my birthday

The question that I have is about how long will the stock gears hold up to this motor with a 3 cell LiPo? I used to run this setup in my mini t with a ball diff and never stripped any gears. Any help would be appreciated.

35/36 gearing :lol:

Calculation could be right but be sure the motor will get that calculated rpm's. No way that the motor will reach 90.000 rpm :roll:

Beside that calculate some loss in your airodynamics and roll-resistance what can go up to 30 or 40% loss at that speed.

Well you may be geared 35/36 but what is the kv on you motor and what kind of batteries are you running that has a lot to do with it. And why do you say that this motor will never hit 90,000 RPM never say never any thing is possible.
