Wing twist, slightly off topic

[Amir Neshati]

Assuming that this airplane flies wings level in the upright attitude with
all this left
trim...what does it do when  you roll it inverted? If it continues to fly
wings level
inverted (no rolling), then you have a twisted wing panel or two...however,
if it rolls left (the same direction as the trim), then your right panel is
heavier...
If you haven't already tried the inverted test, I'd suggest you do it before
you
do the twist and shout ;-)

Have fun,
Amir
