2. Now that we have done the math, measure out 6-1/2”on
each engine box side. Using a square from the top edge draw
a line on the mark with a felt tip pen. Do both sides. Trim
excess off to the line using a razor saw. Now measure up
from the lower front edge 7/8”. Measure back 4=1/4”
drawing a line between the two points and trim off.
3. Install the 1/4” firewall between the sides and flush
with the ends using 5-min epoxy. Pin it to the sides, 3 places,
on each side with 1/16” dia toothpick or nail brad.
4. Construct a center point on the firewall 2-1/8” down
from the top and 2-3/4” in from the left side facing it. Extend
the lines to edges of the firewall.
5. Laminate two ¼” engine shims (not supplied) together
with thick CA. Tack glue to firewall aligning the centerlines.
Match drill the four holes in the engine shim with a ¼” drill bit.
Now remove the shim.
6. Enlarge the four ¼” holes with a 5/16” drill bit. Install
four, 10-32 T-nuts.
7. Apply thick CA to the edges of the T-nuts to hold them
in place. Install ½” tri-stock balsa pieces to reinforce the
firewall. Also add to short pieces in the corner at the former
and sides as shown.
8. Glue on the motor shim with thick CA. Be sure to align the
holes with the T-nuts. Epoxy on the 1/8” lite-ply bottom.
Score at the bend point and crack, do not beak in two, so that
it will fit in one piece. Use 5-min epoxy.
Mount the engine with 4, 10-32 x 1-1/4” socket head bolts
and split lock washers (not supplied). Side thrust can be
added by shimming one side of the engine.
