Step 4
Attach the engine using four #6 x 5/8"
socket head sheet metal screws.
Cool Tip
: Apply a little bar soap to the
threads of the screws to make them easier
to thread into the mount. You can also
remove the mounts and run the screws
through, reattach them to the firewall,
and then bolt the engine down.
Step 5
Determine the proper location for the throttle pushrod.
Mark the location with a felt-tipped pen and drill the
firewall for the pushrod tube using a drill and 5/32"
(4mm) drill bit. Remove the engine if necessary.
Step 6
Test fit the throttle pushrod tube through the firewall
and into the fuselage. Once satisfied with the fit,
roughen the tube using sandpaper. Slide the tube back
into position and use medium CA to glue it to the
firewall. Allow 1/8" (3mm) of the pushrod to extend
forward of the firewall. Trim the throttle pushrod at the
front edge of the doubler on the throttle servo tray.
