Hinging The Rudder; Wing Assembly - Seagull Models SEA12 Assembly Manual

HINGING THE RUDDER.

Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.

WING ASSEMBLY.

We highly recommend using 30 minute
epoxy as it is stronger and provides more
working time, allowing the builder to properly
align the parts. Using fast cure epoxy when
joining the wing halves could result in the glue
drying before the wing halves are aligned
properly which may result in failure of the wing
centre section during flight.
1) Locate the wing dihedral brace. Using a
ruler, locate its centre and draw a vertical line.

2) Test fit the dihedral brace into each wing
half. The brace should slide in easily up to the
centreline that you drew.

3) Remove the brace when satisfied with
its fit in each wing half. Coat dihedral brace
with 30 minute epoxy. Next, pour some epoxy
into the dihedral box in one wing panel.
Epoxy.
Carefully slide the two wing halves together
and firmly press them together, allowing the
excess epoxy to run out. There should not be
any gap in the wing halves. Use rubbing
alcohol and a paper tower to clean up any
excess epoxy.
Apply masking tape at the wing join to hold
the wing halves together securely.

4) Peel off the backing from the self
adhesive covering strip. Apply the strip to the
centre section of the wing starting from the
bottom trailing edge. Wrap the strip all the way
around the wing until it meets the trailing edge
again. Trim off any excess strip.
