Cowl Installation
The cowl is already fit to the fuse at
the factory and only requires a small
amount of work to complete, Test fit
the cowl to the fuse. A small amount
of sanding may be necessary at the
aft end of the cowl for a perfect fit
Once satisfied with the fit, tape the
cowl to the fuse. The cowl is held in
place with nine 3mm by 20mm
screws and blind nuts. Starting at
the top, drill an 1/8”(3mm) hole at
the seam, in line with the scale
dummy screws. Install screw and
blind nut and tighten. Continue
working your way down installing
screws after each hole is drilled to
maintain proper alignment. Remove
the cowl. On the inside of the fuse,
scuff the area around the holes you
just drilled. The blind nuts are install
to the fuse with the flat part of the nut
against the fuse. The blind nut is
held in place with fiber reinforced
epoxy built up around the nut. Install
the cowl and tighten all screws.
Apply epoxy as shown in the photo
and allow glue to cure. Use photo
below as a guide to cut out the hole
in the front of the cowl, the cooling
holes and exhaust holes if
necessary. Leave about 3/8”
(10mm) around the outside for
support.
