COWL ATTACHMENT
forward as possible.
❐
Install throttle servo & attach the EZ connector to the throttle servo
arm. Please adjust with the servo in the neutral position and the car-
buretor at half throttle. This will give you an excellent starting point
for radio setup.
IX. Cowl Attachment
❐
With the engine of your choice installed, it will be necessary to cut
holes in the cowl to accomodate 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
fusalege 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 fusleage 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
template against the cowl. Use a marker to draw inside the template
on the cowl.
❐
As with any cowled engine, you will need to cut adequate cooling
holes, so we have drawn where we will cut them on the front.
❐
Before permanently installing the cowl, we have opted to install a
Thunder Tiger #1115 Precision Fueler Valve.
4. Put the cowl in place. Mark the holes for the cowl attachment
screws and drill using a 1/16" drill bit.
