XP 9303 Heli Radio - Hit HOLD and Jitters like glitching

[altitudeav8r]

With all my 770 and 790's I hit hold on the transmitter on the heli's and everything glitches and jitters really bad, even motor jitters on and off, I have noticed on the screen the HLD/ display with go off and on (quick and intermittent) when the "hold is activated" and thats when it happens, Anybody had this problem or know of a fix.... Thanks

Happy flying

It sounds like a switch defect to me. The fix would be to change the switch.

I had the same thing on my 9303 this spring. It was intermittent but it happened fairly often. It finally got so bad that sometimes I could put it in throttle hold and with the heli and tx sitting on the table, I could just whack the table top and the swash would jitter. My trims were different in throttle hold and you could see the swash moving between the two different trims during autos or sometimes just sitting on a table .

I sent it back to horizon, they couldn't reproduce the problem but they replaced the TH switch anyway. It's been fine ever since.
