What kind of motor and speed controller we need when using 3 cells Li-Poly (11.1V) on the Dragonfly?
We do not recommend using 3 cells Li-Poly on the helicopter. It will over power the motor, and the Feda 2-in-1 mixer speed controller can not handle the current draw. 2 cells Li-Poly will be no problem to the dragonfly and we recommend you to use 3-in-1 GWS Pico board instead of Feda 2-in-1 mixer speed controller.
