3) Slide the wing panel on the aileron until 

there is only a slight gap. The hinge is now 

centered on the wing panel and aileron. Re-

move the T-pins and snug the aileron against 

the wing panel. A gap of 1/64” or less should 

be maintained between the wing panel and 

aileron.

Hinge.

4) Deflect the aileron and completely satu-

rate each hinge with thin C/A glue. The ailer-

ons front surface should lightly contact the 

wing during this procedure. Ideally, when 

the hinges are glued in place, a 1/64” gap or 

less will be maintained throughout the lengh 

of the aileron to the wing panel hinge line.

NOTE :   The hinge is constructed of a spe-

cial material that allows the C/A to wick 

or penetrate and distribute throughout 

the hinge, securely bonding it to the wood 

structure of the wing panel and aileron.

Epoxy.

5) Turn the wing panel over and deflect the 

aileron in the opposite direction from the 

opposite side. Apply thin C/A glue to each 

hinge, making sure that the C/A penetrates 

into both the aileron and wing panel.
6) Using C/A remover/debonder and a pa-

per towel, remove any excess C/A glue that 

may have accumulated on the wing or in the

aileron hinge area.
7) Repeat this process with the other wing 

panel, securely hinging the aileron in place.
8) After both ailerons are securely hinged, 

firmly grasp the wing panel and aileron to 

make sure the hinges are securely glued and

cannot be pulled out. Do this by carefully ap-

plying medium pressure, trying to separate

the aileron from the wing panel. Use caution

not to crush the wing structure.

Work the aileron up and down sev-

eral times to “work in” the hinges 

and check for proper movement.

Note : 

HINGING THE ELEVATORS.

  Glue the elevator hinges in place using 

the same techniques used to hinge the ai-

lerons.
