One thing you can try, and I know this sounds crazy, turn your Tx on and put the throttle at full stick, but make sure it is NOT in Idle up!, then plug the battery in, when you do try to keep your hand on the rotor head should it spin up but it should not do anything, then move the throttle stick the the lowest position. After that unplug the heli then plug the battery back in. That might help, I remember I had to do that on Blazemob's Belt CP V2 when he first bought one.
