Dynaflite DYFA3040 - Manual (Page 15)

Q 19. Cut a stringer from 1/8" x 1/4" x 31"
basswood to length and glue into place to the
bottom of formers AB and BB.The remainder of
this stringer will be used on the top formers.
Ql 20. Bend the forward part of the wing saddle
on the 1/8" ply fuselage side along the
embossed cut line so that it conforms to BB.
Glue it into position.
Q 21. Glue the die-cut 1/8" balsa bottom
bulkhead formers EB, FB, GB, HB and HTW into
position.
l-l 22. Tack glue the die-cut 1/8" ply bulkhead
former DB to the FRONT of bulkhead D. Glue
another 1/8" x 1/4" x 31" basswood stringer to
the bottom of formers DB, EB, FB, GB, HB
and HTW.
Note: The exact position of DB will be
determined when the wing is fitted to the
fuselage. For now, just tack glueit so that the
stringer is straight.
Q 23. Cut and fit the tailwheel mount blocks
from leftover 1/4" x 15/16" balsa using the
fuselage side view as a guide. These mount
blocks are glued to the bottom longeron at an
angle to conform to the curve on bottom
formers HTW and JTW. Sand the blocks as
needed for this angle and glue them to the
bottom longeron.
Q 24. Glue the die-cut 1/8" ply tailwheel mount
into position on these blocks. Glue the die-cut
1/8" ply former JTW to the rear of this
assembly. Glue a piece of 1/8" x 1/4" basswood
stringer between JTW and J.
Q 25. Remove the fuselage assembly from the
building board.
I-] 26. Time to mount your engine. Before you
glue the firewall into position, you should add
some reinforcing sticks to the inside of the
fuselage as shown in the above photo. Use the
1/4" x 3/8" x 36" basswood stick for this purpose
(DO NOT use the longer basswood wing
spars). Glue them into position with 30-minute
epoxy. While you are waiting for the epoxy to
cure you can mount your engine to the engine
mount you have chosen. Position the mount on
the plan at the firewall then locate the engine on
the mount to fit the front of the cowl properly.
Check the position on the model to be sure
blind nuts and bolts will clear the structure. If
