the obvious solution is the wrong solution.
I figured the obvious was to reverse the pitch servo but that is not the answer. Got a clue???
there are 2 ways of changing direction and you'll need to
probably use a bit of one and a bit of the other as you setup the
you only want to use MDL->REV if individual servos are backwards.
say, for example, if both aileron servos went up (or down)
on a aileron command).
You want to use MDL->SWH and flip the +/- sign on the mix for
the function if an entire function is backwards.
if everything is moving correctly except that pitch is reversed
for movement of the left stick, then go into MDL->SWH and flip
the +/- for pitch.
