Assemble The Ailerons - GREAT PLANES Ryan STA EP Instruction Manual

Then, remove the hatch and put a drop of thin CA in each
hole in the rails to harden the wood. After the CA has cured,
replace the hatch and screws.
13. Go back to step 10 and install the other aileron hatch.

Assemble the Ailerons

1. Position the die-cut 3/32" [2.4mm] balsa aileron base
over the plan. Mark the aileron rib locations on both sides of
the aileron base.
2. Cut the 1/4" x 1/2" x 24" [6.4mm x 12.7mm x 609.6mm]
balsa aileron LE in half. Draw a centerline lengthwise on the
1/2" x 12" [12.7mm x 304.8mm] side.
3. Glue the aileron base on the aileron LE along the
centerline and perpendicular to the face of the LE.
4. From the 3/32" x 1/4" x 24" [2.4mm x 6.4mm x
609.6mm] balsa sticks, cut and glue aileron ribs to both
sides of the aileron base, perpendicular to the base.
5. Trim the ends of the aileron LE and ribs flush with
the aileron base.
6. From the remaining 1/4" x 3/4" x 30" [ 6.4mm x
19mm x 762mm] balsa stick, cut and glue aileron tip fillers
on the top and bottom of the aileron.
7. Use a razor plane and sanding bar to shape the
aileron ribs and LE to shape.
8. Position the die-cut 3-ply aileron horn base on the
aileron LE. Mark the outline of the base on the LE. Carefully
trim a recess in the LE so that the base is flush with the LE
and the aileron rib.
9. Glue the horn base to the LE and the rib. Make a
small wedge from leftover 3/32" [2.4mm] balsa to fit
between the horn base and the aileron base.
10. Position the aileron on the wing and mark the
location of the hinges on the aileron and wing.
