Ok so I have tested this idea and it seems to all be in order. I have an ESC from a older helicopter. (Falcon 3d ) And the ESC is for a brushless motor. it also outputs exactly 5V for the reciver and servos. Well why cant I just use this with the Lipo's it came with and comvert my heli into a Lipo powered machine because the flight times are alot better. I have powered my heli with it and it all seems fine. Just wondering if there is something Hidden I dont know about.
