It sounds like its the tail motor is weak. Have you tried holding the heli in your hand and apply some throttle (about 30 percent). Be careful when you do this. Now rotate the body of the heli CCW - the tail motor should speed up in order to counteract the rotation of the body in a CCw direction. If you rotate the body in a CW direction the tail motor should slow down.
