❏ 12. Use a carving knife or a razor plane to shape
the top of the block to match the shape of the wing. Follow with a bar sander and 80-grit sandpaper. Note: When sanding, hold the bar sander on the end over the tip and apply pressure there only. This way, you won’t be sanding the sheeting.
❏ 13. Shape the bottom of the tip to a 45-degree
angle as shown on the cross-section on the plan.
❏ 14. Use progressively finer grades of sandpaper to
final-shape the wing tip and the leading edge of the wing.
BUILD THE AILERONS
Do the left aileron first.
Refer to this photo for the following eight steps.
❏❏1. Cut out the corrugations from one of the die-
cut 1/16" [1.6mm] balsa aileron skins. This will be the bottom, left aileron skin. Hint: A single-edge razor blade works best for cutting, but is too long. Use a cut-off wheel to shorten a razor blade so it will fit in the slots.
❏❏2. Position the aileron skin over the left aileron
plan. Note that the skin is a little wider (from the front to the back) than it needs to be. Mark the leading and trailing edge where the skin is to be trimmed.Trim the skin as needed so it fits the plan. Note: The skin is also a little longer than it needs to be, but it won’t be trimmed until later.
❏❏3. Reposition the skin over the plan. Mark the
locations of the aileron ribs that will be glued on later.
❏❏4. Cut a 3/8" x 5/8" x 18" [9.5 x 16 x 460mm] balsa stick to the correct length for the aileron leading edge. Glue the leading edge to the skin. ❏❏5. Cut the control horn support from a leftover
piece of 1/2" x 1/2" x 24" [13 x 13 x 610mm] balsa stick (there should be a piece left from the fin leading edge). Glue the horn support into position.
❏❏6. Cut sixteen corrugation fillers to the length
shown on the plan from a 1/16" x 1/4" x 30" [1.6 x 6.4 x 760mm] balsa stick, then glue them into position.
❏❏7. Glue the nine die-cut 3/32" [2.4mm] balsa
aileron ribs into position.
❏❏8. Glue the 1/8" x 1/4" x 30" [3.2 x 6.4 x 760mm] trailing edge support into position. Bevel the leading edge, the trailing edge support and the trailing edge of the aileron skin to match the angle of the aileron ribs.
