Preparations; Build The Wing; Install The Ailerons - GREAT PLANES P-40 Warhawk Instruction Manual

PREPARATIONS

❏
1. If you have not done so already, remove the major parts
of the kit from the box and inspect for damage. If any parts
are damaged or missing, contact Product Support at the
address or telephone number listed in the "Kit Inspection"
section on page 7.
❏
2. Remove the tape and separate all the control surfaces.
Use a covering iron with a covering sock on medium/high
heat to tighten the covering if necessary. Apply pressure over
sheeted areas to thoroughly bond the covering to the wood.

BUILD THE WING

Install the Ailerons

❏
1. Test fi t a CA hinge into each of the hinge slots in the wing
panels and ailerons. If necessary, enlarge the slots with a
hobby knife. When satisfi ed with the fi t, insert a CA hinge
halfway into each hinge slot in the wing panels. Push a pin
through the middle of each hinge to keep them centered.
❏ ❏
2. Roughen the portion of the aileron torque rod that
fi ts into the aileron using 220-grit sandpaper. Apply a thin
coating of epoxy to the torque rod and join the aileron to
the wing by fi tting the torque rod into the hole in the LE of
the aileron and the CA hinges into the slots. Wipe away any
excess epoxy with a cloth dampened with denatured alcohol.
Continue on to the next step before the epoxy cures.
❏ ❏
3. Remove the pins in the hinges. Adjust the ailerons
so there is a small gap between the LE of the aileron and
the wing. The gap should be small, just enough to see light
through the gap or to slip a piece of paper through. Apply
six drops of thin CA to the top and bottom of each hinge
without using accelerator. After the CA glue has hardened,
confi rm that the ailerons are secure by pulling on them and
defl ecting them up and down.
❏
4. Repeat steps 2 and 3 for the other wing panel.
❏
5. Locate the two plywood wing joiners. Mix up a small
amount of epoxy and laminate the two pieces together. Join
the pieces together, being sure the edges are as fl ush as
possible. Use alcohol to wipe away any excess epoxy. Make
note of the top side of the joiner. This should face the top of
the wing panels when installed.
