INSTALL THE WING TIPS
❏
1. Place the die-cut 1/8" plywood wing tip
brace on the aft end of the shaped 3/4" balsa
wing tip. Mark the location of the wing tip brace on
all four wing tip sections.
❏
2. Glue two of the wing tip sections together to
make wing tips that are 1-1/2" thick. Do not apply
glue in the area of the wing tip brace.

3. Saw a 1/8" slot along the joint of the wing tips
and glue the braces in the slots with CA. Sand the
aft end of the wing tip to match the shape of the
wing tip brace.
❏
4. Glue the wing tips onto the wing, carefully
centering the tip brace at the TE. Use a knife, razor
plane and sanding bar to shape the wing tips.
BUILD THE FLAPS
❏ ❏
1. Tape the aileron to the wing with a 1/16"
gap between the ailerons and the wing tips.
❏ ❏
2. Place the 3/32" + 1/16" spacer, used
when installing ribs FL-2, on the root of the aileron.
Lay a straightedge on top of the flap ribs and glue
the die-cut 1/8" balsa flap rib (FL-3) to the 1/4"
balsa flap LE. Remove the spacer after the glue
has cured.
