Buy the innovative RCinPower AOS Supernova 1404 4000KV motor for your sub-250g drone!
Get the cutting-edge technology powered by the record-breaking AOS Supernova 3220 engine in a compact package for the most popular class of drones weighing up to 250 grams. This motor is the result of thousands of iterations of finite element simulation, including revolutionary 4D magnetic field modeling, to achieve a previously unattainable balance of power and efficiency.
Created by renowned FPV engineer Chris Rosser, this motor is second to none in its class for 3" freestyle and Cinewhoop drones. If you are looking for maximum performance from your lightweight drone, this motor is your choice.
-
25% more thrust than any other 1404 motor tested, without loss of efficiency .
-
30% more torque thanks to an optimized magnetic system, ideal for heavy Cinewhoop propellers.
-
Highest efficiency, comparable to market leaders, despite a 25% increase in power.
-
The result of cutting-edge engineering: thousands of finite element simulations and 4D modelling.
-
Manufactured by RCinPower using 7075 aircraft grade aluminum and Japanese bearings .
Engineering Excellence and Performance
The AOS Supernova 1404 4000KV is a brushless external rotor motor designed without compromise. Its mission is to provide the best flight performance for sub-250g drones using 2.5" Bullnose or 3" Freestyle propellers with 4S batteries . Thanks to its thicker core and precisely calibrated magnet overhang, this motor offers a huge advantage in controllability and power .
All this was made possible thanks to the exceptional quality of workmanship. The motor is made by RCinPower, a brand known for creating record-breaking powerplants . The body is made of durable 7075 aluminum alloy using N52H magnets. To achieve ideal response, the developers recommend EXPO settings in Betaflight: Throttle MID = 0, Throttle EXPO = 0.20.
