Finish The Model; Install The Cowl - GREAT PLANES P-40 Warhawk Instruction Manual

C. With the female bullet in the open end of the male bullet
and the cutouts in both connectors lined up, apply solder
with fl ux into the cutouts. When applying the solder, it
should appear to fl ow into the joint and around the ends
of the connectors until the joint is coated. Excess solder is
not necessary as it will simply gather at the bottom of the
joint. Use alcohol to wipe the joint clean.
D. When satisfi ed, slide a piece of heat-shrink tubing over
the adapter up to the base of the male bullet connector.
Use a heat gun or micro torch to shrink the tubing onto the
adapter. If necessary, trim the excess heat-shrink tubing
from the end of the female bullet connector.

16. Now is a good time to test the rotation of the motor
before the cowl and prop are installed. Use your radio
system and battery to temporarily power the motor. If the
motor rotates clockwise when viewed from the front, correct
the rotation by choosing any two of the three motor leads
and reverse their positions.

Install the Cowl

The cowl installation is shown on the brushless motor power
system. Installing the cowl over a glow engine is the same.
However, in addition to cutting a cooling hole for the engine
head, you will also need to make a hole for glow plug access, a
hole to access the needle valve, and a cutout for the muffl er.

1. Put four pieces of tape at least 5" [127mm] long onto
the sides of the fuse (two per side) evenly spaced apart
and parallel with the fuse centerline. Make a mark on each
piece of tape in the center of the cowl mounting blocks
that are glued to the edges of the fi rewall. Draw a line using
a straightedge 4" [102mm] long from each mark. Mark the
end of each line as shown. These lines will be used to drill
the mounting holes for the cowl.
❏
2. Fit the cowl onto the fuse. Temporarily install the spinner
backplate onto the motor shaft. The backplate may need to
be reamed or drilled out to match the shaft size (1/4" [6.4mm]
for the 35-30-1450 out-runner, 1/4" [6.4mm] for the O.S.
FX glow engine). Position the cowl so that the front of it is
3/32" [2.4mm] from the backplate, square and is centered
behind it. When satisfi ed, tape the cowl in place.
