Dynaflite DYFA2016 - Manual (Page 7)

D 2. Optional: Drill a 3/16" hole near the bottom
of bulkheads A and B for an antenna guide tube (not
included). The hole in bulkhead B must be slightly off
center so the guide tube will not interfere with the
tow hook block.
Q 7. Use a straightedge and a ballpoint pen to
extend the centerline on the top view of the fuselage
plan an additional 9" from the rear of the fuselage
on the plan. Cover the top view of the plan with wax
paper from bulkhead A to bulkhead D.
LJ 3. Use medium CA to glue bulkhead A to the
right fuselage side so it is even with the fuse bottom.
Use a small 90 degree triangle to hold the bulkhead
perpendicular to the fuse side while you glue.
Q 4. Remove the die-cut 1/16" balsa crutch from
the die sheet and sand off slivers and die-cutting
irregularities. Cut the aft end of the crutch so it
matches the length shown on the plan.
Q 5. Use thin CA to glue the crutch to the right
fuselage side so it is perpendicular and the front of the
crutch overlaps bulkhead A as shown on the plan.
LJ 6. Join the left fuselage side to the right fuselage
side. Accurately align bulkhead A with the lines you
marked on the left fuse side and align the crutch with
the left fuse side. Use medium CA to glue bulkhead
A to the left fuse side.
LJ 8. Position the fuselage on the top view and
accurately align the aft end of the fuselage over the
centerline, then hold it in position with a large T-pin
on both sides. Align the centerline on bulkhead A
with the centerline on the plan. Hold the fuse in
position with a balsa block and T-pins on both sides
of the fuse.
Q 9. Fit, but do not glue, the rest of the bulkheads
between the fuse sides. Use the "balsa block and
T-pin" technique to hold the fuselage in position so
the centerlines of the f o r m e r s align with the
centerline on the plan. Hold the fuse sides to
bulkhead D with masking tape.
U 10. Double-check that the formers align with both
the plan and the lines you marked on the inside of
the fuse sides. Also make sure that the bottoms of the
formers align with the bottoms of the fuse sides. Glue
the formers to the fuse sides with thin CA, followed
with medium CA.
