Hello, I am back.
It appears that whatever Gizmo script that helps control the power/condition controls also messes with my control of the propeller power. The only way I can move the propeller lever is by the mouse, and it is not consistent. Sometimes when click and drag on one of the prop levers and then move the mouse up, it will increase the prop. Other times it will decrease. Sometimes it will jump or stick to a certain point, without any noticable pattern. The same goes for the other direction
Using the keyboard does not work, and using an axis on a joystick or throttle quadrant still does not work with the steps above. If I turn gizmo off, I regain normal control over the propeller control, but of lose control over the other things that is properly being controlled by the script in question.
Any ideas?
