Section 4: Installing the Ailerons
Step 5
Remove the T-Pins and apply thin CA to each hinge.
Make sure the hinge is fully saturated with CA. Use
a paper towel and CA remover/debonder to clean up
any excess CA from the wing and/or aileron.
Step 6
Firmly grasp the wing and aileron and gently pull
on the aileron to ensure the hinges are secure and
cannot be pulled apart. Use caution when gripping
the wing and aileron to avoid crushing the structure.
