You should read the rest of the comments before you post. Might save you looking like a twat. The problem was the rx not gelling with the CP, fixed by installing a servo buffer. Start a working one of these up inside and the servos will stay still until you move it or hold your hand in front of the sensor to simulate the horizon.

And stop using that old fm we're in a 2.4 world now. Good you got it sorted out :)

@jcer93705 Yea I wish I could go to 2.4 but I have a bunch of FPV gear tying up that channel(s). At least there is stuff all others to compete with for channel space down here.

I know someone that wont go to 2.4ghz because they have fpv which run on 2.4. The thing is 2.4 is already mature and alot of people u see now at ircha and other rc airshow are using it but since u have fpv system then fm is alright for mean time. I fly helicopters, i do not want one single glitch one little glitch will cost u over 1000 dollars if you hit good, any large helicopter will munch it hard. Anyways i understand you and by the way most club baning fm radios now.

@jcer93705 I hear you. It makes me nervous alright. I fly heli too using FPV to do AP. I have tried 2.4 tx and 2.4 vid and it glitched the vid something awful. I figure if the vid glitches its all over. At lease if the tx glitches but the vid is fine I may be able to find the pieces. What I probably should do is go 1.3ghz for the vid and 2.4 for the control but after three years of glitch free FM i gotta weigh up the costs. Only one club here (10 members).

I have one I installed. Try to recalibrate it. Also check the sensitivity, it may be set too high.

@sddaniel7 Thanks, Its all sorted now. The problem was fixed by installing a servo buffer on the elevator channel. Now it works great.

Youre surprised it is confused? Youre indoors, the copilot has no clue where the horizon is.

@jcer93705 I use a RCV922 cam, 500mw vid tx and diversity rx both immersion RC and fat sharks. I have to cram it all on a 450 so I run an extension lead on the tx to keep the cg and get the antenna right out the tail, that seems to make all the difference on mine. I also run a head tracker but only on the plane. Copilot is easy to program but it can be bit hit and miss with reliability. I keep it on the plane and run a helicommand on the heli as a panic switch. Its also great for landing in FPV

Let see, i don't think i ever had a glitch with an fm radio, oh wait i had a am radio from futaba on the 90's and it did glitch. But it was am. What type of first person view system you're using? I'm getting a fma copilot this friday when i get paid i will be using on my trex 600 with futaba 8fg so how hard was it to program the damn copilot?
