OK I did find where to change the dual rate assignment and corrected. I even found where it tells you how to do that in the manual. What is confusing and frustrating is you cannot select the parameter on the display. When you put the switch in the correct position and push the enter button weird things happen. Sometimes you get what you want. As you say you have select the dual rate to change then push the enter sw twice then throw the sw to where you want to have it then push the enter again. Weird. Your procedure needs to be spelled out in a manual.
Update: The arrow will toggle. You need to perform this procedure twice sometimes to get the right directions. Very weird
On the throttle all I want to do is be able to throw a switch and limit the throttle advance to about 80% of maximum and be able to adjust the 80% position if I need to. I have it working but it also affects the low throttle position as well
