Dynaflite DYFA2016 - Manual (Page 10)

d 3. Apply 30-minute epoxy to the base of the fin,
the top of the fuse sides and all other mating surfaces.
Insert the fin into the fuse. Clamp the fuse sides to the
fin TE with a clothespin. Push a T-pin through the top
sheeting into the LE to hold the front of the fin down.
Immediately proceed to the next step.
Q 4. Glue the front hatch tongue to the bottom of
the hatch so half of it protrudes past the front edge
of the hatch.
U 5. Use a ballpoint pen to mark the inside edges
of the fuse sides on the aft 2" plywood strip.
Q 4. Make a fillet of epoxy joining the base of the
fin and the fuse. Use a 90 degree triangle to make
sure the fin is perpendicular. Remove the masking
tape before the epoxy cures and do not disturb the
model until the epoxy is fully cured.
Q 1. Cut two 2" pieces and one 5-3/4" piece from
the remaining cross-grain 1/8" x 2" plywood strip.
Use medium CA to glue one of the 2" strips to the
front of the fuselage as shown on the plan.
Q 2. Use the 5-3/4" plywood strip (which will
become the top of the hatch) as a spacer to glue the
other 2" plywood strip to the aft portion of the
fuselage cabin. Leave a small gap at both ends of the
hatch to provide clearance for the covering material.
U 3. Use the remaining 1/8" x 2" plywood strip to
make two 3/8" wide hatch tongues. The aft hatch
tongue should be the same width as the inside of the
fuse sides at the back of the hatch. The front hatch
tongue should be the same width as the fuse sides at
the front of the hatch.
LI 6. Position the hatch on the fuselage and transfer
the marks to the hatch so you know where to glue the
aft hatch tongue. Glue the aft hatch tongue so 1 /8" of
the tongue extends past the aft edge of the hatch.
Q 7. Fit the hatch to the fuselage by first inserting
the front hatch tongue under the front fuse top. Next,
bend the hatch so you can slip the aft tongue under
the aft cabin top. Sand all the plywood pieces so
they are even with the fuse sides.
