TRANSMISSION SETUP

It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance.

The Goblin has many possible reduction ratios at your disposal. It is possible to optimize any motor and battery combination.

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

204

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

H0015-18-S - 18T Pinion = ratio 11.3:1 H0015-22-S - 22T Pinion = ratio 9.3:1

H0015-19-S - 19T Pinion = ratio 10.7:1 H0015-23-S - 23T Pinion = ratio 8.9:1

H0015-20-S - 20T Pinion = ratio 10.2:1 H0015-24-S - 24T Pinion = ratio 8.5:1

H0015-21-S - 21T Pinion = ratio 9.7:1 H0015-26-S - 26T Pinion = ratio 7.8:1
