Hi

I have an unsolved problem with
one of my RCM (which was fixed after crash)
it needs a very large amount of down trim in order to keep
a horizontal flight.

C.G is 100% in place.
Thrust angle seems to be fine.

I suspect that the wing incidence is too high ->
too much pith-up is produced.

any other suggestions?
is 1 deg mistake with the thrust angle can
cause such a pitch-up?
