Great Planes Giles G-202 46 Kit - GPMA0238 - Manual (Page 14)

16. Measure 2-3/8" in from the cut you just made and
cut off the excess sheeting, making a 1/16" x 2-3/8" x 24"
trued aileron sheet.
❏ ❏
17. Place a bead of medium CA along the aileron
portion of each rib, the aileron end cap and the aileron web.
Align the aileron sheeting you just made with the leading
edge of the aileron web and the aileron end cap.
❏ ❏
18. Use a bar sander to shape the LE web so it
aligns with the tops of the ribs and the shape of the airfoil
as shown in the sketch. Be careful not to gouge the ribs or
LE web.
Note: Use this photo for the next three steps.
❏ ❏
19. Weight the wing down directly in front of the
aileron web to keep it flat on the support jig. Hint: An Easy
Touch Bar Sander with a weight on top, or bags filled with
lead shot and sealed shut, makes an excellent wing weight.
❏ ❏
20. Using medium CA, glue a LE sheet to the front
half of the spar. Note: Make sure the sheeting overhangs
R-11 and the center of the wing slightly.
❏ ❏
21. Carefully lift the sheeting away from the ribs, then
apply a bead of medium or thick CA to the top of each rib
and the LE web. Working quickly, pull the sheeting forward
as you press it down to the ribs and the LE web. Use
weights to hold the sheeting to the ribs and LE web until the
CA cures.
❏ ❏
22. Once the glue is dry, lift off the weights and
remove the T-pins from the spars.
❏ ❏
1. From a 1/16" x 3" x 30" balsa sheet, cut two 9-1/2"
long sheets and one 6-1/4" long sheet. These will become
the center sheeting.
❏ ❏
2. Position the first 9-1/2" long sheet over the ribs,
flush with the TE sheeting and overhanging R-4 by 1/4".
Glue in place.
❏ ❏
3. Place the second 9-1/2" long sheet flush against
the first sheet and overhanging R-4 by 1/4". Don’t worry
about it overhanging R-1, we’ll get to that later. Be sure it is
pressed firmly against the first sheet. Lay the straightedge
on the spar, pressed firmly against the trailing edge of the
LE sheeting. Use a hobby knife to carefully cut the second
piece of sheeting along the spar. Remove both pieces of
sheeting and the straightedge from the wing. Glue the
second piece of sheeting in place. Note: You will cut the
opening for the servo after the wing is unpinned from the
building board.
