3220 1000KV Brushless Motor 6061T6 Aluminum Alloy High Torque Low Vibration for AK420 380 400 450 Class Competition Helicopter
Product Description
3220 brushless motor is perfectly compatible with AK420 helicopters, precisely CNC-machined from 6061T6 aluminum alloy.
It features uniquely oversized bearings, high-quality 180° NdFeB strong magnets and built-in high-efficiency active heat sinks for ultra-low operating temperature and improved energy conversion efficiency.
The 3rd-gen 3220 brushless motor adopts 0.86mm single thick copper wire with precise 7T+6T YY winding method, manually wound with high slot fill rate. It delivers powerful output with extremely low vibration, steady enough to keep a coin standing on the aircraft. It is the standard power motor for 380/400/420/450 class competition-grade helicopters.
Notes: Recommended motor timing angle: 5°. Use 60A ESC for daily use, 80A ESC for extreme performance. Mounting hole spacing: 25mm.
