Carefully read and practice the following step
completely before mixing any epoxy. The entire step
must be completed before the epoxy begins to set.

3. When you are satisfied with the fit, pull the panels apart

and mix up a large batch (about 1.5 oz.) of 

30-minute

epoxy

. Using an epoxy mixing stick, liberally spread epoxy

inside both 

of the joiner slots and on one half of the joiner

itself. Next, quickly install the glued end of the joiner into one
of the slots. Spread more epoxy onto the root ribs and the
protruding end of the wing joiner. Slide the two wing panels
together. The epoxy should squeeze out around the edges.
This is a good sign that there is enough epoxy to securely
join the two wing halves. Double check the alignment and
wipe off any excess glue with a paper towel and rubbing
alcohol. Hold the two wing halves together using masking
tape. Continually check the alignment of the wing halves
while the epoxy cures.

4. Once the glue has cured, check the joint for any small

gaps and fill them with epoxy. Wipe off any excess epoxy
using a paper towel and rubbing alcohol. The paper towel
can also be used to remove any fingerprints or epoxy
residue that may have been left behind.

1. Glue the aileron servo tray and uprights into the wing

using 6-minute epoxy.

1. Lay the wing bolt plate on a table with the punch

marks facing upwards. Draw a centerline across the wing
bolt plate. Using a hobby knife, 

gently

score the wing bolt

plate along this centerline. This score line is to allow the
wing bolt plate to be easily bent to the contour of the wing
and should not be cut completely through the plate.

2. Position the 

wing bolt plate

on the trailing edge of

the 

top 

of the wing. Use the centerline on the wing bolt

plate to center it between the aft root ribs. Draw a line
around the plate on the covering using a felt-tip pen.
Carefully remove the covering with a hobby knife. 

Be

careful not to cut into the wood.

3. Using 6-minute epoxy, glue the wing bolt plate in

place with the punch marks facing up. Clamp it in position
while the epoxy cures.

Note

: The following steps depict the installation of a 

2-stroke

engine. The steps are similar if you are using a 

4-stroke

engine, although some changes to the throttle pushrod
routings will need to be made.

Install the Engine Mount

INSTALL FUSELAGE COMPONENTS

Install the Wing Bolt Plate

Install the Aileron Servo Tray
