Aileron issue...
hmmm there is two ways to go about this.
a:
try to fix the warp either with the aileron still on the plane or off it and risk damaging either the plane or the aileron,
or
b:
fly it like it is. 1/8" total warp on a trainer shouldnt make a real diffrence in flight... at worst you would just need a touch of rudder to trim it out. if this was a high performance speed plane then yeah you would want to fix it, but a trainer is alot more forgiving in minor descrepencies like this.
my advice.. go for it.. you probably wont even notice.
