3-piece wing conversion.
outer wing:
Some cracks filled in on the aileron using easy sand.
Dubro heavy duty nylon hinges for the ailerons.
I cut a slot about 1/16" from the top corner and at about a 45 degree angle to 1) give the hinge some meat to hold onto and 2) get the pin of the hinge at the top surface.
TE of flap also sanded to a point to the sub surface 1/64" thick ply.
LE of flap sheeted.
The leading edge of the flaps have to be cut/sanded so they do not interfere with the TE of the wing.
