I have an 800 size traditional helicopter equipped with a Pixhawk autopilot. While in ACRO mode with the throttle armed and in Mode 2, the swash plate will not return to level when the pitch/roll stick is returned to neutral, regardless of whether or not the flight batteries are plugged in. The swash plate performs as it is supposed to when in Stabilized and Auto mode.
Transmitter is a JR X9303.
Any suggestions on how to fix this would be greatly appreciated!

This is actually totally normal. The controller "remembers" that you have requested it to move a certain amount, and it will keep trying to move to that position. It limits the "stored" movement to 10 degrees. You should be able to prove this to yourself by doing a little test:
Starting from a position where the swash is level, push the cyclic forward, and then release. You will see the swashplate remains tilted forward a bit as you have demonstrated. Now, take your helicopter, and just tilt it forward about 10 degrees. You should see the swashplate now returns to level *relative to the airframe, not the ground*.

I have some questions and I think this will be a good place to start. I am building an e flight 500 with a PIXHAWK and DX9 TX. After I follow the basic step up and calibrate the radio. I cannot get the CCPM servo to move up and down enough to do the mechanical calibration to measure the pitch and ensure to have +12/ -5. The swash plate only move like 1 or 2 degree up and down.
Any ideas ?
Can you send me your params?
You're in Stabilize or Acro mode?
Acro Mode
Thanks Rob!
I'm glad to hear that it's operating correctly. I'll stop trying to fix a problem that doesn't exist!
