Important Information about Motor
Selection
We are recommending the E-flite™ Park 370 Brushless
Motor with 4100Kv (EFLM1000) or the Park 400 Outrunner
Brushless Motor, 920Kv (EFLM1305). The Park 370 Brushless
Motor, 4100 Kv provides plenty of power for sport and 3D
pilots with the ability to hover and climb vertically using the
included 6.6:1 gearbox and 12x6 propeller. It is extremely
important to monitor gearbox wear and motor temperature
when using the 4100Kv motor. Lack of proper throttle
management using this motor may result in damage to the
motor, gearbox, ESC, and battery. Proper motor cooling is
very important so make sure the motor is cooled properly in
the cowl. A direct drive Outrunner alternative would be the
Park 400 Outrunner, 920Kv that will also provide plenty of
power without worrying about gearboxes.
