ENGINE BOX ASSEMBLY
1) Cut 1/8” ply engine box sides to correct length to accommodate your engine size (Be sure to cut
from front of engine box sides) An easy way to determine the correct length of box sides is to slide
the cowl just past Former F1 approximately 1/8”. Measure from front of former F1 to front of the
cowl. Now measure the length of your engine. Subtract the engine length from your first
measurement. This should be the required length for your engine box sides. It is always a good idea
to cut the engine box sides slightly shorter then needed, approximately ½”. This will allow you to
make adjustments by adding spacers between firewall and engine. Adding a spacer will also allow
for the rear cylinder to be spaced away from the firewall to allow for better cooling.
*Be certain to
check sides, one is longer then the other, this will give you the correct amount of right thrust.
Measure from F1 to end of cowl to get correct box length
2) Slide engine box sides through former F1, slide notch of engine box sides into former F2. Square
sides to former F1. Using epoxy, glue sides to F1, F2 and fuse floor.
Hole in
firewall to
accommodate
rear intake
style engine.
3) Epoxy plywood firewall to the inside of the engine box sides and flush with the bottom of sides.
4)
Cut 1/8” lite-ply engine box floor to correct length. The floor should rest on bottom of sides and
firewall and butt up next to former F1.
5)
Epoxy engine box floor to the bottom of sides, firewall, and front of former F1. Be certain to square
all parts to former F1.
6)
Use 3/8” balsa tri-stock reinforcement at all glue joints. Behind firewall reinforce glue joint with 3/8”
spruce tri stock.
