Spirit System

After setting up spirit2 on a jumper t16
I have a issue, after powering up the rudder slowly goes full travel in one direction and stays there, I can move stick and rudder will move, but will always creep back to full travel on one direction.
What can cause this?

Thanks

Hi ! Did you disable your rudder trim ?

Hi,

please check Diagnostic tab and verify that Rudder channel is at 0% when sticks are centered.

Hi
I bind the receiver again and all seems to work on the bench.
