NOTE:
1.To purchase the ducted 4S version, please use 40A ESC
2. In order to ensure the efficiency of the ducted power system, the gap between the inner wall
of the duct and the top of the fan blade is only 0.5mm. During the production test, the tester need
to hold the duct driving force in the debugging operation. When debugging the power, because
the gap between the inner wall of the duct and the top of the wind blade is very small, if the
Tester use too much force, the wind blade and the duct ring are easy to rub, so a small amount of
scratches will be produced on the inner ring of the duct. But after such power debugging, the ducted
system can work normally without vibration.
