You can’t repeat this enough when you’ve bought a new hardware peripheral:
Go through ALL the bindings and make sure you’re removed any duplicates - they WILL step on each other in flight and you will wonder why things have gone crazy.
Don’t forget to Apply & Save when you make those changes. See point 1 to verify.
I removed my throttle axis binding from my TCA controller when my Logitech Quadrant showed up. Didn’t hit apply and save. Kept wondering why a) power inputs were spurious during the test flight, and b) why the blessed heck was it acting like P-factor was on steroids and fishtailing like mad? Doh. Removed binding, didn’t apply and save.
