What you will need in this chapter:
Entire airframe
Provided hinges
Not Provided:
30 to 45 minute epoxy
Two cycle oil
9. Now were going to prep the hinges for installation. Take a small drop of oil and place it in each of
the pivot points of your hinges. The oil prevents excess epoxy from bonding the joint
(figure 72).
10. Working with one panel and control surface at a time, apply epoxy into the hinge holes of the
trailing edge. Apply epoxy to one side of the hinges and insert them into the holes
(figure 73, 74, and
75).
11. Apply epoxy into the leading edge holes of the control surface and the other side of the hinges.
12. Carefully insert the control surface into the hinges and butt the two surfaces together. Move the
surface up and down a couple of times to make sure all the hinges are aligned correctly and the desired
throw is attained. 35 degrees for ailerons and 45 degrees for all others
(figure 76).
13. Use some masking tape to hold the surfaces together and let cure for at least eight hours. Repeat
these steps until all of the surfaces are epoxied in place
(figure 77).
