COWL ATTACHMENT
IX Cowl Attachment
❐
With the engine of your choice installed, it will be necessary to cut
holes in the cowl to accommodate cylinder heads, needle valves, glow
plug access, etc. In order to do this, create a template in the following
fashion: With engine in place, tape strips of standard paper to the fuse-
lage over the area that will need to be removed from the cowl. Make
sure the pieces of paper are long enough to cover the cowl.
Tape the paper into place against the fuselage and carefully draw
around the necessary areas. Now using an Xacto knife, cut out the
drawn area.
❐
Now remove the engine, put the cowl into place and tape the tem-
plate against the cowl.
❐
Use a marker to draw inside the template on the cowl.
❐
Trim away the mark position you drew and trial fit on the fuselage
as shown.
❐
Install the muffler and use the same way to trim the cowl.
❐
Before permanently installing the cowl, we have opted to install a
Thunder Tiger #1115 Precision Fueler Valve. Set the cowl in place.
Mark the holes for the cowl attachment screws and drill using a 1/16”
drill bit.Attach the cowl using the four 2.6x8mm Wood Screws.
