Has anyone measured the gear reduction used in the rotor to compute the raw speed of the motor. I have always been a fan of checking theoretical calculations with actual measurements to make sure we stay within the ballpark.
Fortunately I have never had to take my G5500 apart so have never checked the gear ratio.
