AOS Supernova 4220 350Kv

AOS Supernova 4220 350Kv is a powerful motor suitable for large VTOL aircraft, heavy-lift, and long-range drones with 13-15" propellers and a 6-8S LiPo battery. The motor belongs to the Supernova series, designed by Chris Rosser based on his own FPV motor performance model and manufactured in collaboration with RCinPower. 

The stator has a 42mm diameter and 20mm height in a 12N14P configuration, with a winding resistance of 43mΩ. The motor achieves its highest efficiency, over 86%, in the 5-16A range. With 13-15" propellers, this corresponds to approximately half throttle, making the motor suitable for aircraft focused on long flight times. Propellers mount onto a 6mm hollow shaft or with four M3 screws on a 12x12mm bolt pattern in the bell. The motor mounts to the frame with four screws through M4 30x30mm mounting holes. It weighs 330 grams (with 3cm wires). We recommend pairing it with ESCs rated for at least 80A.
