Gerry I appreciate the work you put into the manual. The only real issue I had with the manual was trying to figure out how to program/map the buttons, and what the mappings do. Other than that it's a good writeup.
I figured out how to set both endpoints. Instead of turning the wheel to switch directions, I had to pull the trigger, even for steering endpoints (Ch1). Not sure why that is but I'm fully up and running, other than mapping the buttons.
