A high quality, reasonably priced 40A 3-6S LiPo brushless speed controller
The new Hobbywing FlyFun 40 Amp speed control is economically priced and ideally suited for medium-large sized builds. It's rated for a 3-6S Lipo, and up to 60 amps burst (10s).
Inside the ESC is the new DEO technology (Driving Efficiency Optimization), allowing for better throttle response, improved efficiency, and better thermal performance.
It also features multiple protections, including start-up, over current, thermal, overload, failsafe, and inconsistent voltage input to increase the lifespan and reliability of the ESC.
The integrated BEC is more powerful than many other speed controllers, capable of 8 amps continuous current and up to 20 amps for short periods of time while switchable between 5.2, 6, and 7.4 volts. This ESC is fully compatible with the HobbyWing Programming card for ease of use.
These ESCs are also able to enter a 'reverse mode' to shorten your landing distance, taxi, or reverse out of trouble on a float plane.
