This completes the basic fuselage structure.
Pylon Assembly:
26)
You will need the parts shown in this photo: The pylon
core, 2 each pylon forks, pylon spacers, pylon sides and the 1/8
birch dowel. The dowel will need to be cut in half and then both
of those pieces cut in half again so that you have 4 equal length
pieces.
NOTE:
the servo cutouts are made for Hitec HS-225mg
servos. If you are not going to use those servos, now would be
the time to 'make adjustments' to the pylon core. It is highly
recommended to stay with the 225mg servos.....
27)
Temporarily align each fork with the 4 holes and mark on the INSIDE
surface of the forks along the top of the pylon core. This is simply a reference
mark on where to apply the epoxy glue. The entire 'fork' assembly can be done in
one setting using 15 minute epoxy glue. The holes for the 1/8” dowel fork pins
are all pre-drilled. Apply epoxy to the inside surface of both balsa fork spacers
and align them with the 4 holes. Push a 1/8” dowel piece through each of the 4
holes with an equal amount extending out on both sides of the pylon. Coat the
inside surfaces of both forks with epoxy up to the mark you previously made.
Also apply some epoxy to the 4 dowel pins. Align the forks to the pins and slide
onto the dowels. It is a good idea to clamp the assembly together while the glue
cures. After the glue cures the dowel pins can be sanded flush with the forks.
The picture shows how it should look when finished.
NOTE:
The pylon spacers are very slightly oversize to allow for sanding to
perfectly match the plywood forks.
