To use the following motor cross-reference chart, scroll down and find the size motor you are looking for.  There is a chart for
22mm motors, 30mm motors and 40mm motos, based on approximate stator size.  Find the manufacturer of the motor that
you want to compare, then find the model of the motor, and finally, go over to the left column to find the closest matching
Scorpion Motor.  Due to the variation in Kv and motor sizes, there will be slight variations in exact motor size and power, but
the following charts will get you as close as possible to a matching motor in terms of weight, power output and Kv.
