Step 4
Install the 8-32 blind nuts from inside the fuselage. Seat
the blind nuts by tightening the bolts. Remove the bolts
and carefully glue the blind nuts in place with thin CA. Be
sure not to get any CA on the threads of the blind nuts.
Step 5
Install the engine mount rails using threadlock and a
9/64" hex wrench. Next, loosely mount the engine to the
rails and measure 5

" from the firewall to the prop drive
washer of the engine. Tighten the mounting hardware to
secure the engine in place.
Step 6
Determine the proper location for the throttle pushrod.
Mark the location with a felt-tipped pen or pencil and drill
the firewall for the pushrod tube using a drill and 5/32"
drill bit. Remove the engine if necessary.
Step 7
Test fit the throttle pushrod tube through the firewall
and into the fuselage. Once satisfied with the fit, mix 1/4
1/4 ounce of 6-minute epoxy and glue the pushrod into
the firewall. Allow the epoxy to cure.
