Dynaflite DYFA1009 - Manual (Page 22)

LI 2. Position former F2 on the right fuselage side so
the aft edge aligns with the guideline you made. Use
a builder's triangle to hold the former perpendicular
to the fuse side. Glue it in position with thin CA.
Q 3. Glue former F3 to the right fuselage side the
same way.
D 4. Without using any glue, join the left fuselage
side to the right fuselage side. Then place the
assembly over the top view of the fuselage plan.
Q 5. Align F2 and F3 and the fuselage sides
between F2 and F3 with the plan. Align F2 and F3
with the guide lines on the left fuselage side, then
hold the fuselage to the plan so the sides are
parallel. Check and double check that everything
aligns. Finally, use thin CA to tack glue the formers
to the left fuselage side.
Q 6. Inspect the fit and alignment of the fuselage
sides and the formers, then securely glue the formers
to the fuselage sides with medium CA.
Q 8. Accurately align F4 with the guidelines you
drew and align the top and bottom of the aft
fuselage sides. Glue F4 in position with thin CA.
Q 9. Remove the rubber bands. Temporarily clamp
the ends of the fuselage together with a piece of
1 /8" x 1 /4" balsa to simulate the spacing of the fin
TE. If necessary, trim the triangle sticks at the aft
ends so they do not interfere.
LI 10. Position the 1/8" x 1/4" balsa spacer and
the clamp so the top of the fuselage aft of F3 will
fully contact the plan. Align the top of the fuselage
sides aft of F3 with the plan, then pin the fuselage
sides to your building board over the plan.
Ql 7. Position former F4 between the fuselage sides.
Hold the rear of the fuselage sides together with a
few small rubber bands.
Q 11. Use a builder's triangle to align the front of
the fuselage over the plan, then use thick balsa
blocks (you may use the cowl blocks) pinned to the
building board to hold the front of the fuselage in
alignment over the plan.
