Neu motor rpm speed question for BrianG

[BrianG]

I dunno.

I kinda work backwards. First, I estimate the motor series (1515, 1521, etc) I'll need based on vehicle size/weight. Then, work backwards with my desired speed and gearing to calculate the motor rpm I'll need. Then, the kv is determined by the motor rpm and voltage I plan to use. This is the method my calc program uses for the motor estimator.

If I know I'm looking for an unusual application, like super high speed where tall gearing is necessary, I'll go up on the motor series to give extra torque to compensate.
