If it helps, the rocker on this throttle has an axis with a center.
It works well for rudder, zoom & other things that go back and forth, but return to neutral(center).
L & R Toe Brakes need an axis that is 0 to 100 (or 100 to 0 , if reversed)
If i remember correctly, the rocker can be set as 2 buttons also? See the programming manual.
You could set Left rocker to keystroke brakes when held down(this would apply both left & right, just like using the default keyboard button
and
what ever you wanted for the Right side, like reset view forward.
