D 31. Drill two 3/32" holes through the rudder using the
control horn as a guide.
round off the corners with a
sanding block. Test fit the doubler
into the front of the plastic
fuselage tube as shown in the
photo. The firewall doubler
should fit into the fuselage with a
snug but not tight fit. The front of
the fuselage is cut at a slight angle
so the firewall and thus the engine
will point down slightly. Because
of this angle the top and bottom
edges of the firewall doubler are
also cut at a slight angle. Make
sure you install the firewall
doubler so all of its sides match
up nicely with the sides of the
fuselage as shown in the sketch.
D 32. Secure the horn to the rudder with two 2-56 x
5/8" machine screws. The screws should thread into
the nylon "nutplate" on the opposite side of the rudder.
Although not necessary, you may use some wire
cutters or an abrasive cutoff wheel to cut the screws
off even with the plate.
D 33. The other control horn should be installed on the
top surface of the elevator about 1" to the right of the
centerline. Follow the same procedure for installing
this control horn.

D 35. The 3/8" plywood firewall doubler is now glued to
the 1/4" plywood firewall front. Use either Thick C/A or
epoxy and make sure that the front of the firewall
doubler is centered on the back of the firewall. Wipe
away all excess glue that squeezes out.
D 36. Draw a vertical and horizontal centerline on the
1/4" plywood firewall. Cut the engine mount template
from the back of this booklet and tack glue it to the
firewall, aligned with the centerlines. Drill a 1/8" bolt
hole at each of the marked locations.
