autorotate

With so many electric helicopters coming from china and hong kong, I'm becoming confused to which version dragonfly i have. on the outside of the box it says feda but on the instructions it says jabo. I hav'nt managed to fly it above waist height yet but now have a major problem. When main motor only is connected to the board it spins. When servos connected both motors and servos don't work. Servos connected and motor disconnected, servos still won't work but sometimes give a faint twitch.two boards on helo. would appreciate any help
