STEAM-RC MD3220 1000KV Brushless Motor 0.86MM Wire Diameter for 420 RC Helicopter

The 3220 brushless motor is suitable for 420 helicopters and is manufactured using 6061T6 aluminum alloy with high-precision CNC machining. Its distinctive large bearing design, 180-degree high-quality neodymium-iron-boron strong magnets, and built-in efficient active heat sinks provide ultra-low temperatures and effectively improve energy conversion efficiency.

The third generation 3220 brushless motor uses 0.86mm single-strand thick copper wire, 7T 6T YY precise winding method, and is hand-wound with high slot fill rate. It delivers powerful performance while maintaining minimal vibration; a coin can stand on it when mounted on a helicopter. It is the standard power motor for competition-level 380/400/420/450 class helicopters.

Note: It is recommended to set the motor to 5° timing. For daily use, a 60A ESC is suitable, while an 80A ESC can reach its maximum performance. Mounting hole distance: 25mm.
