Use a hobby knife to remove the plywood from the firewall
to provide cooling air to pass through the fuselage. The
plywood has been partially cut so all that is required is to
score the plywood along the lines.
 Step 2
Use a hobby knife and a covering iron to open the cooling
air exit in the bottom of the fuselage. Cutting the covering
1/8-inch (3mm) inside the opening and ironing the
covering into the fuselage will leave a clean look to the
bottom of the fuselage as shown.

outer holes in the X-mount as shown.
