Do the top wing first.

❏

2. Lay the top wing upside-down on your building stand

or workbench (covered with a towel). Enlarge the factory-
punched holes near the leading edge in the bottom of the
center panel using a 3/32" [2.4mm] drill (there are two holes
near the leading edge and two holes near the trailing edge).
The holes only need to be 1/2" [13mm] deep. A 3/32"
[2.4mm] wheel collar or a block of wood could be used to
keep the drill from going too far. If installing the optional
flying wires, drill out the two additional holes behind the aft
wing bracket holes as well.

❏

3. Use #4 x 1/2" [13mm] screws to mount two each of the

C3 and A3 metal brackets as shown. Note that the shorter
surface of the C3 brackets contacts the wing. Also mount
two B2 metal brackets for if installing flying wires. Note that
the shorter part of the B2 brackets contacts the wing.

❏

4. IMPORTANT! Remove the screws, harden the holes

with a few drops of thin CA, allow to harden, then reinstall the
brackets with the screws. As you proceed, this procedure
MUST be done for all the screws that hold on the brackets.

❏

5. Enlarge the holes in the outer panels for the bracket

screws the same way. Mount the A2 and C2 brackets. If using
flying wires mount the B1 brackets as well. Remove the
screws, harden the holes with thin CA, allow to harden, then
reinstall the brackets and screws. Set the top wing aside.
