PAGE 18 CHAPTER 10 / INSTALLATION OF THE MOTOR
It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance.
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 120 teeth for the main gear and
the tooth count of your pulley as the pinion count.
Below is a list of available reduction ratios:
19T Pinion = ratio 6.3:1 22T Pinion = ratio 5.5:1
20T Pinion = ratio 6:1 23T Pinion = ratio 5.2:1
21T Pinion = ratio 5.7:1 24T Pinion = ratio 5:1
The Devil 380 accepts a wide selection of batteries with different capacities. The suggested number of cells is 6.
All batteries from 1500 to 2600 mAh offer good performance.
We recommend the use of an 1800 mAh battery for the perfect compromise between weight and performance (3D flight).
Larger capacity batteries (2200-2600) increase flight times at the expense of weight and reduced agility (Sport flight).

NOTE
: Although the Devil can handle even higher RPMs, for safety reasons we suggest to not exceed 3600 RPM.
