❏
22. Locate the die-cut 1/8" plywood hatch retainer
(HR). Center the hatch retainer on the bottom (unpunched
surface) of the die-cut 1/8" plywood tank compartment
hatch with approximately 3/8" protruding from the rear,
then glue it in position.
❏
23. Position the hatch on the fuselage and drill 1/16"
holes through the punch marks in the hatch into the firewall.
Remove the hatch, then enlarge the holes in the hatch
only with a 3/32" drill bit. Temporarily mount the hatch to
the fuselage with #2 x 3/8" screws.
❏
24. Glue the two die-cut balsa cabin top fillers in the
notches on both sides of the windshield.
❏
25. Test fit, then glue the die-cut stab base and the
tapered balsa tail wedge into the aft end of the fuselage.
Trim the tail wedge as necessary for a good fit.
Skip step #26 if you are building the bolt-on wing version.
❏
26. Slightly chamfer the ends of the two wing dowels,
then test fit them through the holes in the fuse. Hint: Run a
1/4" drill through the fuse sides to make sure the holes are
all lined up. Remove the dowels until the model is
covered. You will be instructed when to glue the dowels in.
❏
1. Test fit, but do not glue, the grooved hardwood
landing gear (LG) rail in the slot on the bottom of the fuse.
It should fit snugly in the space between the ends of the
bottom sheeting and the notches in the fuse sides.
❏
2. See the following photo at step 4. While the rail is in
position (but not yet glued) test fit the two die-cut 1/8"
plywood landing gear doublers (LGD) and the hardwood
landing gear blocks. Note: The grain direction of the LG
blocks is vertical (as shown on the plan).
❏
3. Remove all the landing gear parts, then mix enough
30-minute epoxy to glue the LG rail and the LG blocks. Glue
the LG rail to the fuse sides and fuse doublers with epoxy,
then glue the LG doublers in position with medium CA.
Immediately proceed to the next step.
