We carefully filed the top and bottom of the flap actuating arm slots in
the side of the fuselage to act as the up and down stops for the flaps.
File a little at a time on each side as you get close to the final position
as altering the top stop on one side has a slight opposite effect on the
other side . With this method you can very accurately adjust for the
correct flap movement on each side. We also reinforced the inner skin of
the fuselage in the area of the top and bottom of the flap slots with two
layers of bid and flox to thicken it in the area where the flap actuating
arm will abut it.
