❏ ❏ 4. Use some coarse sandpaper to roughen the
inside of the ply hatch and the end of the mounting
block. Glue the mount to the hatch with 30-minute
epoxy, centering the servo arm over the opening in
the door. Secure the blocks in position by screwing
the block to the hatch with one #2 x 3/8" [9.5mm]flat
head screw in each block
❏ ❏ 5. Cut the aileron and flap hinge blocks to the
size shown on the plan and glue in place. Trim any
excess wing sheeting. Sand and shape the leading
edge and wing sheeting.
That's it for the bottom of the left wing. Build the right
wing half, by repeating the same steps!
Joining the Wing Halves
❏ 1. Locate the two die-cut Leading Edge Dowel
Braces and glue them together with 5-minute epoxy.
❏ 2. Locate four die-cut Wing Bolt Mounting
Plates. Glue two of them together with 5-minute
epoxy. Do the same for the remaining two plates.
❏ 3. Using 5-minute epoxy, glue a wing bolt
mounting plate in position in the slot between W1
and W2. Glue the doubler W1D and W2D in position
on ribs W1 and W2 to support the mounting plate. Do
this for both wing panels.
❏ 4. Cut a slot in W1 and W2 as shown in the sketch.
This slot is needed to allow clearance for the die-cut
1/8" ply [3.2mm] wing spar web brace and the
die-cut 1/16" [1.6mm] ply dihedral brace. Do the
same for the other wing panel.
❏ 5. Test fit the wing spar web brace into the slot you
cut into the ribs.
❏ 6. Test fit the dihedral brace into the slot and make
sure it fits well with the spar web brace.
❏ 7. Use 30-minute epoxy to glue the wing spar web
brace and the dihedral brace to one wing panel. Be
sure to use enough epoxy to assure a good bond of the
web brace, dihedral brace and the spars. When the
glue has fully cured we will glue the two halves together.
