Beginners Note

 
These instructions were written assuming that the builder has previous building experience. If this is your frrst model then we 
recommend that you purchase a copy of the following book: 
 

Rubber Powered Model Airplanes By: Don Ross

 

 
This excellent book covers basic building and flying procedures and provides valuable information about all aspects of building 
and flying rubber powered model airplanes.
 

Building the Fuselage

 
1.

 
Pin the fuselage plan to the building board and cover it with wax paper.

 
2.

 
Pin the fuselage keel pieces K-1 through K-6 into position on the plan.

 
3.

 
Laminate parts F-3, F-3A, and F-3B together. Make sure stringer notches are aligned with each other. Be sure to make 
one left hand and one right hand.

 
4.

 
Position F-1 on the front of K-1 and K-6. The top of formers F-1, F-2, F-4, F-5, and F-6 are determined by a "v" notch 
located on the inside of the formers. Use a small square to hold F-1 at a 90 degree angle to the building board. Glue F-1 
into position.

 
5.

 
Carefully glue formers F-2 through F-8 into position on the fuselage keel making sure that they are at 90 degrees to 
building board.

 
6.

 
Position the master stringer F-9 onto the fuselage assembly and make sure that it is pressed in completely before glue is 
applied.

 
7.

 
Glue the 1/16" sq. fuselage stringers into position. Note: Start at the rear of the fuselage and work toward the front.

 
8.

 
Remove the fuselage from the plan. Add the formers to the opposite side of the keel and glue the master stringer into 
position. Now glue the remaining stringers into position.

 
9.

 
Glue pieces F-10, F-11, and F-13 into position. Cut to fit, position, and glue 3/32" x 1/4" balsa for rigging as shown on 
fuselage plan.

 
10.

 
Laminate parts F-12 to F-1. The basic fuselage structure is now finished. Now sand the fuselage smooth all over. Sand 
and round off the F-12's as shown on plan.

 

Building the Cowl

 
11.

 
Pin C-1's to fuselage plan.

 
12.

 
Glue C-2, C-3, and C-4 to top and bottom C-1's making sure that they are at 90 degrees to the building board.

 
13.

 
Position and glue the main cowling stringer C-1 onto the assembly.
