Glue 1/8” square balsa stringers in place between N1
and N6.
Plank the nacelle with 1/4" x 1/16” balsa strips. Begin
with the strip nearest the building board. Note that the strip
must tip inward to meet the formers – see the plan for a detail
sketch. This helps the plank correctly fit the shape of the
nacelle.
Laminate three N10 pieces together and glue them to
the rear of the nacelle.
Glue 1/4” long 1/8” diameter dowels in the vertically-
opposed holes in the firewalls N1.
If using Speed-400 motors, glue the two 1/4” square
hardwood motor mounts in place. Note – you can also use
these motor mounts to strengthen the firewalls for brushless
motors.
Glue the upper portions of N1, N2 and N3 to the
nacelle bottom. Add a 1/8 square balsa stringer between N1
and N3.
Sheet the upper portion of the nacelle from N1 to N3
with 1/16 balsa.
Cover the nacelle as desired. We suggest using 1/2-
ounce fiberglass cloth and epoxy finishing resin for extra
strength, as this is the part of the model that contacts the
ground upon landing.
Pull the motor wires through the wing and nacelle, and
out through the firewall. Glue the right-side nacelle to the wing.
Cut the nacelle fairing from 1/16 balsa and glue it in
place.
Repeat for the left nacelle.
