AOS RC Supernova 4220 Motor

The AOS Supernova 4220 is a 415KV heavy-lift motor designed by AOS RC and manufactured by RCINPower for large VTOL aircraft, heavy-lift multirotors and long-range drones on 6–8S. Its 42 x 20 mm stator turns 13–15-inch props and produces more than 8 kg of thrust on a 15-inch tri-blade.

Key features

• 8434 g peak thrust on an HQProp 15x7x3 at 32 V
• 12N14P configuration with 30 mΩ internal resistance
• Hollow 6 mm shaft: props fit on the shaft or bolt to four M3 holes on a 12 x 12 mm pattern
• Frame mount uses four M4 screws on a 30 x 30 mm pattern
• Leads are only 3 cm long, so plan on extending them to the ESC

Use an ESC rated for 80 A or more per motor, as peak draw reaches 86.9 A. The 30 x 30 mm M4 pattern suits large heavy-lift arms and motor mounts rather than 5–7-inch FPV frames. A hardware set is included.
