I have the same problem.I'm using APM Planner 1.1.91 via 3DR 915MHz. Joystick works fine before any connection. But after Connection, I move the controller from down to up. the throttle bar in radio calibration only show 999-1000. other control bar also shrink about 50%.Help?

Michael, do you have any suggestions to solve my joystick controlling problem? (Joystick is Logitech Extreme 3 pro) Ctech4285 says that I have to verify 100% that your actual output is not ch(x). I don't know how to do that?

What firmware did you reload APM or Radio? I have problem of controlling with joystick, only buttons work. The green bars move when moving stick but nothing happens to servos?

APM 1

i am flying quad and as far as i know the servo output is low unless your armed, look at the tuning graph for your ch1in. if eg ch1in is correct but you don't see anything on ch1out then its the arming 

btw if you are using the logitec controller you can not arm the quad in the standard US configuration, at least that was the case in arducopter 2.5ish

I looked at the status page on mission planner and when I move the joystick the ch1in and ch1out readings change and they show readings 1098 left 1524 center 1941 right,but ailerons don't move.

chXout is the actual value that gets send to the pwm generator, i would double check everything looks like a setup error, ah and if those are some fancy digital servos RTFM the servos

I think it is not servo related because it is same problem with esc/motor too.

And when I enable joystick I'm still able to move servos with normal radio...I thought that MP should disable normal radio when joystick is enabled?

well since you have ch(x)out responding correctly to the joystick you should verify 100% that your actual output is not ch(x)out. i think the only thing that can overwrite ch(x)out is fail safe mux which passes your normal radio straight throw the output.  the normal radio should not be disabled because you need it as a backup when your link goes down.
