 Step 1

Mount the cowl using six 4-40 x 1/2" socket head screws 

and six #4 washers. Use small pieces of fuel tubing on 

the screws to keep them from vibrating loose. Make the 

appropriate cutouts in the cowl for the muffler exhaust  

and engine cooling.

 Step 2

Install the propeller and spinner.

Note

: The scale propeller is shown in the 

photo. Do not attempt to fly the aircraft with 

this propeller as it is for display only.

 Step 3

Cut out the instrument panel decal and apply.
