Wing twist, slightly off topic

[Bob Kane]

I recently finished an ARF scale project. During the
initial flights, I had to put in a lot of left aileron
trim to sustain level flight. The wing is a two piece
affair joined with a heavy-walled aluminum tube and
located with a steel pin. The root ribs of the wings
are aligned, so there is obviously a twist built into
one or both wing panels. Does anyone have a method to
"untwist" a completed wing panel? The
construction appears to be a standard "D"
tube, sheeted up to the spar, open bay behind the
spar. They are covered with some kind to heat shrink
film.   Thanks.
