RCInPower AOS RC Supernova 1605 3900KV Motors

The 3.5” Freestyle Performance Champion

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 3.5” Freestyle drones of course!

If you are seeking the ultimate performance for your 3.5” freestyle build, this is it. Built on the world-drone-speed-record-breaking technology of the AOS Supernova 3220, the AOS Supernova 1605 is engineered to deliver the Torque, Power, and Performance you need, precisely matched to a 3.5” tri-blade Freestyle prop. (3.5” cinewhoops with bullnose props should use larger 2004 size motors).

The motor is optimized for driving 3.5” Freestyle Tri-blade props on 4S battery voltage. On the thrust test stand and in the air, Chris Rosser found the Supernova 1605 drastically outperforms other 3.5” motor options (1404, 1804), producing massively more thrust and a much faster response without sacrificing efficiency. The Supernova 1605 broaches no compromises. 3.5” Freestyle has never had a powerplant like this.

Built on the incredible success of the AOS Supernova 2207, 2807, and 3220 the 1605 takes the same revolutionary design philosophy and scales it down for the challenging demands of 3.5” freestyle pilots. Thanks to thousands of finite element simulations, including 4D field modeling for the first time, the Supernova 1605 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 1605 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 1605, you can experience 3.5” Freestyle the way the FPV Gods intended.

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.
