9. The wings are assembled around 3 CF
Spars. When gluing the pieces together
it is advisable to build around these
spars as it ensures correct alignment.
Often the ends of the 3D printed spar holes will require a little cleaning up with a craft
knife. The flaps use a torque tube system similar to the tail. Assemble the
Inner and
Outer Flaps , and Wing 2 around the torque tube first. The flaps should be aligned to each
other and glued to the torque tube. The long Aileron and Flap Hinge Spar then passes all
the way through the wing. You
can build the rest of the wing up
in any order after this, ensuring
that no glue is applied to the
ailerons, and they are free to
rotate around the hinge. Position
the Aileron control horns so that
the hot end if over the hinge.
The Flap horns should be placed
2cm further Aft, i.e, these
shouldn’t line up with the hinge
line.
10. At this stage it is a good idea to
assemble all the parts together,
running the servo wires and extensions forwards to make sure they are long enough.
11. Glue Fuselage 3 into position. You can now feed all the wire bundles forward making sure
they are out of the way either side of the gear retract cutout.
12. If using the retractable gear assemble these pieces together as per the images earlier in
this document. It is highly recommended that you use a strong filament for these pieces.
ALWAYS check the pieces for fit in the fuselage to make sure you get them in the right
