Unmatched performance for sub-250g 2.5-3” Cinewhoops and Freestyle quads.
What do you do when you’ve broken the world drone speed record with a motor capable of 580 kph? You bring that technology to the most popular drone category in the world: Sub-250g!
If you are seeking the ultimate performance for your sub-250g build, this is it. Built on the world-drone-speed-record-breaking technology of the AOS Supernova 3220, the AOS Supernova 1404 is engineered to deliver more torque, more power, and a more exciting flying experience than any 1404 before it.
The motor is optimized for driving 2.5” Bullnose or 3” Freestyle Tri-blade props on 4S battery voltage. On the thrust test stand and in the air, Chris Rosser found the Supernova 1404 outperforms any other 1404 motor he’s tested on the market, producing more thrust and a faster response without sacrificing efficiency. The Supernova 1404 broaches no compromises, delivering the smoothest footage on a Cinewhoop and also blowing away the competition in dynamic freestyle flying.
Built on the incredible success of the AOS Supernova 2207, 2807, and 3220 the 1404 takes the same revolutionary design philosophy and scales it down for the challenging demands of sub-250g drone pilots. Thanks to thousands of finite element simulations, including 4D field modeling for the first time, the Supernova 1404 delivers an exhilarating combination of control, power, and efficiency, all in service of the ultimate in-flight performance.
Exceptional designs require exceptional execution. That’s why the AOS Supernova 1404 is manufactured by RCinPower, a brand synonymous with race-winning and record-breaking motors. This partnership, coupled with AOS’s cutting-edge design approach, ensures that this motor not only meets but exceeds the expectations of the most demanding pilots. With the Supernova 1404, you can experience more than ever before, and still stay under 250g.

For smooth, precise low-throttle control and breathtaking top-end power, AOS recommends applying throttle expo in Betaflight. Start with Throttle MID = 0 and Throttle EXPO = 0.20, adjusting EXPO to fine-tune your desired throttle response. Increase EXPO for greater precision at low throttle or reduce it for a sharper, more aggressive feel.
