I have a JR x9303 heli radio,I fly it on a raptor 30 v2 with an OS 37 engine , JR 921 receiver with extra remote, spektrum flight log...sometimes the radio seems to get "stuck" in throttle hold.(After the radio is in throttle hold ,I switch back to normal and the throttle servo will not move). Example: I fly heli in ST1 do tricks ,FFF,then switch to normal mode for landing,I land ,then hit throttle hold while I am walking to heli to shut it off, now I lower throttle trim and put throttle lever to idle and switch to normal mode ...expecting engine to shut off ... But...now in normal mode the throttle will not respond at all...it says its in normal on the screen but the throttle does not move?I check the battery pack 6.2 volts ,I check the antenna performance on flight log ...it is Perfect. It does this 3 out of ten times when Im flying ,but on the bench it always seems to work fine...This happens with no governor installed...Any ideas? Thanks...

Sounds like a bad throttle servo or connection.

Quick check, when it does it, flip to the servo monitor screen and see if the bar is moving and the servo isn't.

Ya you know I just figured that out...Ill bet the throttle servo is getting a workout while flying and when it goes into hold its hot and resting ,when it goes back to normal it doesnt move,Ill bet if you touched it while working the stick it would start working again...makes sense that it never does it on the bench,its not hot enough...I have ruled out loose connections...Im sure thats it,time to rip me out a servo...Case closed...thanks

I put a new servo in the Heli and it worked great...Thanks !

What kind of servo is it? Perhaps your answer is right here.... I had similar results with an 810T servo installed on the throttle of one of my bigger helis running regulated 6 v.
