ÿ 1 ­ engine cowl
ÿ 5 ­ hardwood blocks
ÿ 5 ­ wood screws
The firewall is angled for the right thrust and down thrust
Locate and Epoxy the 5 hardwood cowl blocks to the Fuselage firewall
as shown. You may want to roughen the firewall to ensure a better
bond for the Epoxy.
Using a black marker, put a dot in the center of the wood blocks.
Make up some hole locators using card stock or heavy paper. Punch a
1/8 inch hole in one end and center this hole over the black dot on the
wood blocks.
Tape the other end of the card to the Fuselage.
Slide the cowl over the engine with the proper clearance for the
propeller back plate (about 1/8") and align the side graphics so that they
are straight and even.
When satisfied, mark through the holes in the cards onto the cowl.
Remove the cowl and drill 5 – 3/32 inch dia. holes.
Cut out the necessary holes in the cowl for the proper engine cooling
using a rotary tool like a Dremel.
NOTE: The rule is 2­3 times as much area as the intake area.
When satisfied, secure the cowl to the Fuselage using the supplied
hardware. (5 wood screws).
