Tread looker on contr fork for pitch

[Kavala]

Just before I lost my best heli to day. Pitch contr fork for the tail rotor unscrewed and tail control got lost resulting in spinning heli. Managed to land it , low hight saved it from crash. I never had tred looker between the fork and the slide bushing ( PV 0425) , have done that now. Should there be tread looker ? Have any one exp the same?

Have had my 720e for about 4 years now. Did have that happen one in the early stages of this machines life. Weird, mine happened during spool up right before lift off. I did apply some type of thread locker and have not had it happen again. In fact, have not had any problems with this machine and I could not tell you how many hundreds of flights it has logged.

It needs Loctite. I had mine come off once. The copper sleeve has Right Handed Thread, so it won't be self tighten.

Tanks guys after addng tread looker it works great. Very good heli, my favorite but this part should be self tightening.
