So I have my top speed touring car project underway, and actually got one of the harder things figured out already, but now am torn with a motor/esc choice. Usually I'm having the opposite problem.

My problem is that I have it geared crazy high final gear ratio, 1.67:1. Even on a light touring car, that is still pretty tall.

So I can't decide on a motor for this. I'd like to use a small size, like the Neu 1509 2400 k/v in the RCM store, but wonder if I need to go up to the 1512 series, for a bit more torque.

I want to use a Neu motor for sure. My Kv rating should stay around the 2000 mark (ideas here too).

I was actually thinking of using a Mamba Max 4600 setup, but am not sure that it can handle that kind of gearing without heating up (kv high).

Throw me some ideas on this gloomy Thursday.......
