heli has been flying perfect.............all of a sudden, it starts to do piros and I have no tail control.............lucky to land without incident.........I have checked everything on the heli I know to check and everything appears to function properly...........it acts like gyro is reversed but it isn't.........tail servo working fine..........belt fine..........thought maybe my tail rotor came loose from the tail hub but it is fine.............even checked the one way bearing on mail shaft and it is locked in ok...........tail rotor spins ok and changed pitch properly but when I spool up, it just wants to sit and spin.............any ideas?

What tx and gyro are you using?

Could you have accidently moved the rudder adjustment on the tx

Is your gyro still coming up in heading hold mode?

Is your slider on your tail moving freely and all the way in both directions.

Are you blades chewed up, mains or tail?

Are your tail blades spinning fast enough?

Did you have a hard landing, or make adjustments on your tx just before this happened?

Is your battery good in the tx?

There are numerous posts from guys who have experienced slippage of one of the tail belt pulleys (front or rear). Apparently, either pulley is capable of slipping on the shaft that it is mounted on.
