EDGE 540. Instruction Manual.

1) Carefully remove the aileron from one

of the wing panels. Note the position of the

hinges.

2)Remove each hingefrom the wing panel

and aileron and place a T-pin in the center of

each hinge. Slide each hinge into the wing

panel until the T-pin is snug against the wing

panel. This will help ensure an equal amount

ofhingeisoneitherside of the hinge linewhen

the aileron is mounted to the aileron.

HINGING THE AILERONS.

Work the aileron up and down several

times to “work in” the hinges and check

for proper movement.

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.

Remove the T-pins and snug the aileron

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

shouldbe maintained betweenthe wing panel

andaileron.

HINGING THE ELEVATOR.

Note:

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,makingsure that theC/Apenetratesinto

both the aileron and wing panel.

Glue the elevator hinges in place using the

same tectniques used to hinge the ailerons.

The control surfaces, including the

ailerons, elevators, and rudder, are

prehinged with hinges installed, but the

hinges are not glued in place. It is

imperativethat you properlyadhere the

hingesin place per the stepsthat follow

using a high-quality thin C/A glue.

Note:

4)Deflect the aileron and completely

saturate each hinge with thin C/A glue. The

material that allows the C/A to wick or

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:

C/Aglue.

7) Repeat this process with the other wing

panel, securely hinging the aileron in place.

6) Using C/A remover/debonder and a

papertowel,remove any excessC/A glue that

may have accumulated on the wing or in the

aileronhinge area.

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

applying medium pressure, trying to separate

the aileron from the wing panel. Use caution

not to crush the wing structure.

1) Using a ruler and a pen, locate the

centerlineof thehorizontalstabilizer,at thetrail-

ing edge, and place a mark. Use a triangle

and extend this mark, from back to front,

across the top of the stabilizer. Also extend

thismark down the back ofthe trailing edge of

the stabilizer.

 3) Slide the stabilizer into place in the pre-

cut slot in the rear of the fuselage. The stabi-

lizer should be pushed firmly against the front

of the slot.

 4) With the stabilizer held firmly in place,

use a pen and draw lines onto the stabilizer

where it and the fuselage sides meet. Do this

on both the right and left sides and top and

bottom of the stabilizer.

the stabilizer mounting platform sides.

 5) Remove the stabilizer. Using the lines

youjust drew asa guide,carefully remove the

covering from between them using a model-

ingknife.

When cutting through the covering to

remove it, cut with only enough pressure to

only cut through the covering itself. Cutting

into the balsa structure may weaken it.

 6) Using a modeling knife, carefully re-

move the covering that overlaps the stabilizer

mounting platform sides in the fuselage. Re-

move the covering from both the top and the

bottom of the platform sides.
