TRANSMISSION SETUP
It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance.
It is recommended to use wiring and connectors appropriate for the currents generated in a helicopter of this class.
If you are using a head speed calculator which requires a main gear and pinion tooth count, use 212 teeth for the main gear
(this takes into account the two stage reduction) and the tooth count of your pulley as the pinion count.
BELOW IS A LIST OF AVAILABLE REDUCTION RATIOS:
H0175-18-S - 18T Pinion = ratio 11.8:1 H0175-22-S - 22T Pinion = ratio 9.6:1
H0175-19-S - 19T Pinion = ratio 11.2:1 H0175-23-S - 23T Pinion = ratio 9.2:1
H0175-20-S - 20T Pinion = ratio 10.6:1 H0175-24-S - 24T Pinion = ratio 8 .8:1
H0175-21-S - 21T Pinion = ratio 10.1:1 H0175-25-S - 25T Pinion = ratio 8.4:1

*First put the belt on the motor pinion.
*Then put the belt around the big pulley.
*Rotate the motor several times by hand.
*Pull on the motor mount to tension the belt.
*Rotate again the motor several times by hand.
*Provide the correct force, and properly tension the belt.
*Tighten the M5 nuts first, then the (2) M3 screws later.
