 Step 1
Attach the muffler to the engine using the hardware provided
with the muffler.
 Step 2
Connect the lines from the fuel tank to the engine and
muffler. Make sure the vent line goes to the muffler, and the
line from the clunk to the carburetor.
Note: We used a fuel filler dot to allow for fueling the
engine from the outside of the cowling. This makes
fueling the engine much easier than removing the
cowling before each flight.
 Step 3
Carefully cut the opening in the front of the cowling to allow
cooling air to pass through the cowling.
 Step 4
Use hobby scissors and a hobby knife with a #11 blade to
trim the cowling to fit your particular engine and muffler
combination. Make sure to leave enough gap between the
cowl and engine components so they do not chafe or cause
cracking to the cowling. Use a rotary tool with a sanding
drum to smooth any rough edges left from the trimming
process.
 Step 5
Position the spinner backplate on the propeller adapter. The
hole may be larger than the adapter shaft, so a spacer has
been included to take up any space if the shaft and hole in
the backplate are different sizes.
 Step 2
Slide the cowling on the front of the fuselage. Use four 3mm
x 15mm socket head machine screws to secure the cowl to
the front of the fuselage. A 2.5mm hex wrench or ball driver
will be required to tighten the screws.
 Step 3
Slide the propeller adapter included with your particular
motor on the motor shaft.
 Step 4
Position the spinner backplate on the propeller shaft. The
hole may be larger than the adapter shaft, so a spacer has
been included to take up any space if the shaft and hole in
the backplate are different sizes.
 Step 5
Slide the propeller on the propeller shaft. Make sure it is
facing the correct direction to operate properly.
 Step 6
Use the propeller nut included with your P-51 Mustang to
secure the propeller and spinner backplate to the motor.
Tighten the propeller nut using a 12mm box or open end
wrench. It may be necessary to use the spinner backplate
spacer to take up any extra space between the hole in the
backplate and propeller adapter.
 Step 7
Use the included spinner bolt to secure the spinner cone in
position, Use a 5/32-inch hex wrench or ball driver to tighten
the bolt to secure the spinner cone.
