Note: Although the Goblin can fly at high rpm, for safety reasons we suggest to not exceed 2300 rpm.
Some example configurations:
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
214
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 11.9:1 H0175-22-S - 22T Pinion = ratio 9.8:1
H0175-19-S - 19T Pinion = ratio 11.3:1 H0175-23-S - 23T Pinion = ratio 9.3:1
H0175-20-S - 20T Pinion = ratio 10.7:1 H0175-24-S - 24T Pinion = ratio 8.9:1
H0175-21-S - 21T Pinion = ratio 10.2:1 H0175-25-S - 25T Pinion = ratio 8.6:1
