Help: Recently,my Blade is acting weird. When i connect the battery, I'll hear the servos kick in as usual and then I hear a hiss that I am not sure where it is coming from and in a few seconds the main blade kicks in, seemingly at full throttle but only for a split second. The tail rotor spins briefly at the same time. This happens even though my gyro initializes normally with transmitter on. I notice that if I give it throttle from the TX, it will keep this from happening for awhile but it will repeat itself evey few seconds otherwise. If I disconnect the motor from the receiver, the servos twitch madly instead. The controller is not working correctly either. As I increase throttle, the tail rotor does not begin to spin normall unless I twirl it manually and even then it does not spin fast enough. I thought the latter problem was a bad tail motor but replacing it did not help. Any suggestions?
