Can anyone help with a problem I have with my Honey Bee CP2 please? When I turn on the transmitter and plug in the battery to the helicopter the 4 in 1 blinks and then turns solid green.  Everything works except the throttle - it will increase the pitch on the blades but the rotors wont turn.  When the throttle is increased the light on the 4 in 1 goes from green to red and the rotors dont turn at all.

The battery is okay and the batteries in the transmitter are okay.

I would really appreciate it if someone could help me with this as it is driving me crazy. Thank you.
