Instruction manual

❍ 10. Test fit the wing joiner into one wing panel, then the

other. Be certain the joiner is installed upright with the

joiner angled upward for wing dihedral. Also make sure that

the joiner slides in all the way to the centerline. Test fit the

wing panels together with the joiner. Make certain both

panels fit well.

❍ 11. The measurement for this wing is 5-1/4” [133mm]

plus/minus 1/2” [13mm] from the top of your table to the

highest point of the wing tip as shown in the photo. To

check that this is correct, join the two wing panels together

with the joiner in place. Lay the wing on a flat surface with one

panel flat on your bench or table. To do this you will need to

allow the trailing edge of the wing to overhang the edge of your

table in order to avoid the aileron torque rods as shown in the

photograph above. After making sure the root ribs are fitting

together with no gaps on the top or bottom of the wing,

measure the distance from the bench surface to the wing tip.

If this measurement is not 5-1/4” [133mm] plus/minus 1/2”

[13mm] make adjustments in the plywood joiner. (It is possible

that the joiner may require slight sanding to remove slivers of

wood or excess epoxy that may interfere with the fit).

❍ 12. Once satisfied with the fit of the joiner and the wing

has the proper dihedral, it is time to glue the two panels

together. First thoroughly coat the inside of both pockets

where the joiner fits and one half of the joiner with 30-

minute epoxy. Making certain the joiner is upright and

insert the coated end into one of the wing panels. Coat the

other end of the joiner and both wing root ribs with the

epoxy and join the two wing panels together.

❍ 13. Wipe away any epoxy that squeezes out from

between the wing halves with paper towels saturated with

alcohol. Use masking tape on the top and bottom to hold

the wing together as shown. Be certain the root ribs on the

ends of the wing panels accurately align. Again, wipe away

excess epoxy and do not disturb the wing until the epoxy

has fully hardened.
