Installing The Ailerons And Servos - Carf-Models MiG-15 Construction Manual

3. Installing ailerons and servos
Working Steps:
- install hinges and control horns to the ailerons
- install ailerons to the wings
- cut rear former of wings, install aileron servos and linkages.
You need:
- drill bit 5mm, round file, cutter, long phillips screw driver
- dremel milling tool, small pliers
- 5 minute epoxy (NO CA-Glue!!!)
- both wings and ailerons
- 6 Robart hinges, 2 small phenolic control horns, 2 servos
- servo installation hardware such as screws, extension
servo lead, 2 pieces M3 all thread, 4 clevis and 4 M3 nuts.
Robart Hinge
Installing the ailerons is an
easy job, installing the servos
is a little bit more delicate....
Every aileron is mounted with 3
Robart hinge pins. Drill 3 holes
in each aileron, as seen on the
bottom photo. Open the holes
in the fiberglass to an oval
shape, so that the hinges can
move free.
Gue in the hinges in one line
into the aileron. Use only 5
minute epoxy. See the drawing
for the principal of the working
hinge.
Make sure that you under-
stand, that the point of rotation
is NOT at the leading edge of
the aileron, but in the center of
the curved leading circle! So
glue the hinges into the wood
only.
Tip for the Pro's:
In case of the MiG-15's swept
back wing the hinges should
not be mounted perpendicular
to the leading edge of the
aileron. They should be
mounted parallel to the
aileron's tip. Otherwise you will
have a difficult time to insert
the alileron into the wing. If you
drill the holes and glue in the
hinges parallel to the aileron tip
this makes the assenbly much
easier. Of course the axis of
rotation of any hinge will not be
in one line then, but the
flexibility of the hinges and
thereally small travel of the
ailerons allow definitely to do it
this way. So make sure that
you drill all holes in the correct
angle, in aileron AND wing.
