Note
: There are two engine installations
in this instruction manual (Section 10A
and Section 10B). Section 10A covers the
installation of the Saito™ 1.80. Section 10B
covers the installation of the Zenoah® G-26.
Note
: The P-47 comes with the blind nuts
preinstalled in the firewall. They are located
for the installation of the Saito 1.80-size
four-strokes. If you plan on using another
engine, you may need to remove the blind
nuts and drill new holes in the firewall for your
particular engine.
Step 1
Locate the engine mount and the associated hardware.
Attach the mount to the firewall using four 8-32 x 1"
screws and four #8 lock washers.
Step 2
Temporarily install the engine to the rails using four
8-32 bolts, four #8 lock washers and four lock nuts.
Leave the bolts loose enough to allow the engine to slide
on the engine mount.
Note
: The engine mount is embossed with the
correct orientation for the mounts.
Step 3
Position the engine so the distance from the firewall to
the drive washer is 5

/

". Tighten the screws holding the
engine to the mount. An 11/32" socket wrench will make
this task a lot easier.
Step 4
Attach a brass connector to the throttle arm using the
connector backplane. Assemble the throttle pushrod using
a 4-40 clevis and 12

" 4-40 pushrod. Slide the pushrod
through the installed tube from inside the fuselage and
through the connector.
Note
: The carburetor will have to have the
throttle arm facing away from the engine
centerline and towards the engine mount.
Note
: Do not install the screw in the brass
connector at this time.
