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 207 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:
NOTE: For safety reason we recommend not exceeding 2600 RPM.

These are pulleys for motors with a 6 mm shaft. Each pulley includes an adapter for motors with a 5 mm shaft.
When using 600mm main blades, we recommend a reduction of about 100 RPMs. We also recommend going down one tooth on the motor pulley for better governing.
NOTE: When using 600mm main blades, we recommend not exceeding 2500 RPM for safety reasons.
