AOS Supernova was developed by FPV YouTuber Chris Rosser, who is known primarily for testing drone parts. This is a premium motor that ranks among the best on the market. The motor is manufactured by RCinpower, which is known for its quality craftsmanship.
The 1605 3900Kv motor is suitable for use with 3.5–4" propellers and a 4S battery. The motor bell is made from a durable aluminum alloy 7075 and uses high-quality bearings from Japan. The motor is wound with a single wire with heat-resistant insulation up to 260 °C and uses curved magnets N52H. The motor has a shaft diameter of 1.5 mm and secures the propeller with two screws (T-Mount).
AOS 1605 weighs 13.3 g with shortened wires. The motor is the result of extensive simulations, including 4D modeling of the magnetic field, optimizing it for the best balance between performance and efficiency. More about the motor can be found here or in the video below.
