3220 brushless motor is suitable for AK420 helicopter and is made of 6061T6 aluminum alloy with high-precision CNC machining. Distinctive large-sized bearing design, 180 degree high-quality neodymium iron boron strong magnetic field, and internal high-efficiency active heat dissipation fins bring ultra-low temperature and effectively improve energy conversion efficiency.
The third generation 3220 brushless motor adopts 0.86mm single strand thick copper wire, 7T+6T YY precise winding method, pure manual high slot full rate winding, strong power, but extremely low vibration value, can hold coins on the plane, and is specially equipped with a power motor for competition level helicopters of 380/400/420/450 level.
Attention: It is recommended to set the motor to a 5 ° angle. Daily use of 60A electronic speed regulator, 80A can achieve maximum performance. The distance between the installation holes is 25mm.
