Before joining the wing halves, run your aileron and flap wiring with 22
guage servo wire. I have had great success with MPI products. Now shape
the leading edge with a wood plane. Most foam cores come with the
dihedral angle cut into the root facing. If not, you will have to use a T bar
and 80 paper to sand the recommended angle on the root facing. If you are
glassing with polyester resin, use yellow glue to join the wing halves, if
glassing with epoxy resin, you can use epoxy. I mix epoxy and talcum
powder to a paste that wont run while curing. Use a long flat board and
prop up the tips as to get a nice flush fit at the root and let dry.

Use 1/2in balsa sheeting to make the wingtips. It may take 2 or 3 layers
depending on the thickness of the tip. Cut out the shape with a scroll saw
and draw a center line all around the tip block. When you glue on the tip
block(with Pica Glu-it) line up the very leading edge and the center of the
trailing edge with the line you drew around the block. When dry, use a
wood plane and a T bar with 80 paper to shape the tips, trailing and
leading edges. Cap the exposed foam at the root of the flap with 1/16 balsa
and Glu-it. Use a scroll saw to cut off about 1/2in of the root end of the
flaps, this will give room for end cap balsa and gaps between surfaces.

At this point, deceide on the hinging method and shape to use on the
leading edges of the control surfaces. See photos for an idea and use a
wood plane to shape the leading edges of the flaps and ailerons. In this
case I am using Robart large scale pin hinges. Now cap each surface ends
with 1/16 balsa and yellow glue. Use proper size drill and drill all the
control surface leading edges, now put them in their place and mark the
trailing edges of the wing for corresponding holes.
