Section 4: Ailerons Installation Section 4: Ailerons Installation (continued)
Required Parts
Wing • CA hinge (8) •
Aileron (left and right) •
Required Tools and Adhesives
Thin CA • T-pins •
Step 1
Locate 8 of the CA hinges. Place a T-pin in the center of four of
the hinges.
Step 2
Place the hinges in the precut slots in the aileron (or wing
if you prefer). The T-pin will rest against the edge when
installed correctly.
Step 3
Slide the aileron and wing together. The gap between
the aileron and wing should be infinitely small,
approximately 1/64-inch.
Hint: Be careful of the T-pins, as they can be sharp.
Step 4
Use a ruler to align the end of the aileron to the wing.
Note: Do not use CA accelerator during the hinging process.
The CA must be allowed to soak into the hinge to provide the
best bond. Using accelerator will not provide enough time for
this process.
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.
Step 7
Work the aileron up and down several times to work in the
hinges and check for proper movement.
Step 8
Repeat Steps 1 through 7 for the remaining aileron.
