Use an “X” mount with a mounting bolt circle of 75mm to
mount your motor. Use the 4mm bolts and washers.
Add removable thread locker during installation.
The prop backer plate should be 84-85mm from the
motor mounting box. This will provide clearance
between the cowl and the motor backer plate.
The prop backer plate will be 160-161mm from the
fuselage firewall.
Cowl & Canopy
Apply
painters’
tape over the mounting tabs to transfer
the mounting locations to the cowl. Push a pin through
the tape and hole in the mounting tab.
Peal back the tape to uncover the mounting tabs and
install the cowl but leave the tape on the fuselage. Tape
the cowl into position centering it to the motor using
your spinner’s back plate
as a guide and aligning it to the
top edge of the firewall.
Drill a 1/16” hole
in the cowl through the locating holes
you created in the tape.
Use 3mm wood screws to mount the cowl.
Remove the cowl and apply thin CA glue to the mounting
tabs and screw holes. (Allow plenty of time for the CA
glue to dry before reinstalling the cowl.)
