Afterwards fit the retract plate into the U-shaped milling of the compartment
frame. Please make sure the retract runs parallel with the fuselage to allow the
strut to retract properly in and out.
Furthermore you need to provide a cut-out on frame no 3 for the gear cylinder.
Install the retract and the strut including the wheel. Cut the fuselage skin
according to the size of the nose gear making sure you have enough clearance.
Mounting of elevons
Mark and cut 3 hinge locations in each of the elevons making sure they are well
spaced out. The wing and elevons have balsa inserts to accommodate the hinges.
Glue the hinges in place using good quality epoxy or equivalent. Be careful that
the joints of the hinges keep free of epoxy (if necessary bedabble them with some
oil or silicon) to ensure their flexibility. For safety reasons we recommend to dowel
the hinges additionally, so that they are unable to loosen while flying. Therefore
you need to drill a 2 mm hole through the wing and the elevons at each position a
hinge is located. Afterwards you can fix it by gluing a shortened toothpick in the
holes. Finally you only need to grind overlapping parts of the toothpick smoothly
with the wing respective the elevons.
