Well one day I flew the heli too far and caused to go out of range and crashed, I hope that just what it was (Esky RX).
Then I installed known working PCM Futaba RX that come with my FutabaTX, it was causing trouble, servo jittering etc, then after I took it apart it worked fine.
Installed on the rebuild heli. Did range check and worked. Flew a bit ok. Land to adjust tracking and thing took off by it self and crashed near me.
Now I got all the missing part and rebuild the heli. I don't know which RX to use.. just hope that its not the tx!
