ENGINE INSTALLATION:
1. Depending on which motor you choice to use, you may need to use some of the engine stand offs
provided to get the required cowl clearance. If you use the Hacker A50-14S or equivalent you will need
about 3/16” spacing. If you use the Dualsky motor that OMP sells in the combo package, you will need to
make 5/8” stand offs. See picture below that has the standoff options to use. I prefer the ply stacked
pieces with the CF facing for my standoff. You can also use the heavy plastic tubing also.
2. Place the cowling in place on the fuselage and measure the distance from the firewall to about 1/4” in
front of the cowling. This figure represents the back of the spinner and will help you determine if you
need to space your engine out from the firewall using washers or additional wood dowel offsets. Mount
your engine securely using bolts, washers, and locknuts. There are blind nuts installed in the back of the
firewall for the bolts supplied. I use nylon lock nuts behind the firewall to provide a very secure mounting
that will not come loss.
