I really don't want to tear down my EP to count teeth so does anybody know what the drive train gear ratio is on the Concept EP SR?

Thanks,
Malorie

Formula I use:

Motor RPM/v * ~1.1v/cell * #cells * #pinionT/RPM * 16/63(EH035) * 1/73(EH034) = approx max rotor RPM

I take 75 - 85 %, which is the motor sweet spot.

So is 16/63 the first gear ratio and 1/73 the second?

So the approximate value of the gear train come to 287.4 teeth by my calculations.
