RCinPower AOS Supernova 1605 Motor
Rs. 1,899.00
The AOS RC Supernova 1605 3900KV is a 3.5" freestyle motor tuned to match a 3.5" tri-blade prop on 4S. It shares its design lineage with the Supernova 3220, was tuned and tested by Chris Rosser, and is manufactured by RCinPower. (For 3.5" cinewhoops on bullnose props, a 2004-size motor is the better match.)

Features
- More thrust on a 3.5" freestyle prop than 1404/1804-class motors
- Thicker flux ring and tuned magnet overhang for stronger torque and better propwash handling
- Light for its power output
