Thank you for the insight, Jim. You describe exactly what I'm experiencing, and I happen to use a CyborgX as well. So maybe you gave me the needed hint – I'll focus on the Joystick next! Before, I suggested the issue to be a software problem, being rather sure to have pressed F1 as well during my test flights... but thinking again I'm not fully sure. So that's first.
Thank you and regards
Mick
