1. Place the fuse upside down in a cradle to prevent
damage to the turtle deck while finishing the bottom of
the fuse.
6. Insert the 48" inner pushrods into the outer pushrod
tubes. Check for any binding of the pushrods. The outer
pushrod tube holes in the formers may need to be adjusted.
7. Once the inner pushrods move smoothly, glue the
outer pushrods to the formers and firewall.
2. Use 30-minute epoxy to glue 1/2" triangle sticks along
the bottom front of the retract plate and flush with the bottom
of F-1. Do not cover the blind nuts with the triangle sticks.
3. If you are using a nose gear retract, mount it on the
bottom of the retract plate. You may need to lengthen the
slot in the retract plate for the actuator arm and widen the
slot for the nose gear strut in former F-2.
8. If you are using retracts, thread 2-56 x 1" threaded
studs (not included) 1/2" into the end of the steering inner
pushrod and the retract inner pushrod. Thread a nylon
clevis (not included) 13 turns onto each stud. Connect the
clevises to the retract and test its operation.
9. If you are using retracts, mount a 2" nose wheel on
the nose gear strut at the location shown on the plan. Cut
off the excess nose gear strut.
between formers F-2 and F-3 with the tab on the tank floor
resting on former F-2.
4. Glue the 1/8" die-cut plywood tank floor (TF)
5. Roughen the 48" outer pushrod tubes (the pushrods
for the retracts are not included). Install the throttle,
steering and retract (if retracts will be used) outer pushrod
tubes through the firewall and formers to the servo tray in
the tail. The throttle outer pushrod tube should protrude 1"
from the front of the firewall.
10. Cover the forward bottom fuse from the firewall to
former F-3 with the 1/4" x 3" x 24" balsa sheet. Glue the
sheeting (crossgrain) to the fuse side doublers, formers and
the triangle sticks only. If using a nose gear retract, cut a
clearance hole for the retract mechanism, strut and wheel.
Sand the sheeting flush with the back of former F-3.
11. Cover the rear fuse bottom from former F-6 to F-8
with 1/8" x 3" x 24" balsa sheet. Glue the sheeting
(crossgrain) to the fuse side doublers, formers and the
