My Blade CX 2 Lower Rotor Won't Stop

[helithunder]

I have a Blade CX 2 RC helicopter that the lower blade motor wont turn off unless you unplug the battery. Doesn't matter if the controller is on or off. As soon as the battery's plugged in it starts spinning and wont stop.

2 things come to mind:
Run your throttle trim down.
Center your yaw (rudder) trim.

Helithunder Try to rebind your cx2 an transmitter make sure the throttle trim button is at it's lowest point and throttle stick once it's binded always turn your transmitter on first & then plug in the heli and dont move it till your 3 in 1 unit light is solid green. Make sure you always unplug you battery from the heli before turning your transmitter off. If you turn on your tx & then plug in the battery to your heli if the green light doesn't light solid check your throttle stick & throttle trim. When binding the heli & tx unplug the motors keep up with how the motor plugs plug in for the motors to spin in the right direction. Once it binded unplug the heli first and then the tx remove the bind plug and plug the motors back in and see if that takes care of the problem. when you bind the heli & tx you will plug in the battery and power up the heli & then turn on the tx with motors unplugged. Even the cx2 could cause a bad cut and if your motor is spinning without tx input just be careful.
