I'm late to this post, so forgive me if you've covered this before...But you do know that the ALL of the flight sims frequently assign ridiculous assignments to any USB "Human Interface Device" (HID) device that the can detect??
For instance, on the
Saitek Throttle Quadrant, what would normally be the throttle lever often gets assigned to the
rudder or
ailerons. You'll push the throttle forward and the plane veers off to the side. Great.
Even buttons get assigned to weird commands.
I find that it's best to delete all assignments, one device at a time. Completely.
Ignore the keyboard assignments, but delete ALL of those buttons and lever (axis) assignments. It's a pain in the butt, but it's also the best way to do it.
Strangely, the only "automatic assignment" that never seems to be wrong is the "hat" assignment, so you can leave that one.
So, to me, it sounds like you have a lever or button that has an odd assignment.
Like you, I have a CH Products yoke, and I like it. But I also have a Saitek rudder peddles.
If you want to start fresh and get full command, you'd need to delete the rudder and other axis from both the CH yoke and the peddles.
For what it's worth, the "rudder peddles on the CH yoke can be made to zoom in and out, but you would need something like FSUIPC to do that.
There is one problem that I've come to recognize - the plane will suddenly go to the left or the right.
Whenever that happens I have to pull the peddles away from the partial backstop on the desk. It'll push the peddles one way or the other.
Live and learn.
