I just got my APM2 soldered and installed on my delta. My only problem is that the Elevon #1 servo doesn't response my controls. In any mode. It does move correctly in 'stabilize' when it is controlled by APM. But when I move my stick, only Elevon #2 moves. Any idea why this is happening?
Also, I would like to know what are all those jumpers for? JP1-JP4.
Is your RC transmitter in elevon mode?
I can fly my plane without the APM.
Did you do a RC setup in the MP, and select "elevon" mode?
I did calibrate my radio and put a check in 'Elevons', 'Elevons Rev' and 'Elevons CH1 Rev'.
The Roll and Pitch bars move when I move my transmitter stick. So I guess APM gets the signal but doesn't put it in the output pin #1.
But both servos move in stabilize mode?
Yes. Stabilization signals go on both servos. But, yet again when I try to move them with my transmitter, only #2 moves.
Why is nothing connected to APM Input 1? I fly elevons all the time and they work fine--I think whatever is going is due to a configuration problem in your setup. Are you sure you're doing it *exactly* as per the manual?
I disconnected Rx from the input #1 just to test what is the problem with it. :)
If nothing is connected to APM Input pin #1, shouldn't ch1in be around 1500? Instead of 1245.
Yes. Did you solder the APM 2 yourself? If so, you probably have a solder error.
Yes I did solder it. Have been trying to find a short or something without any luck.
Everything else works. Just ch1in - ch1out is crooked somehow.
Check with your multimeter and see if there's continuity across the CH 1/2 signal pins. If so, you've shorted it somehow.
