Glue the two F4L BRACE parts in place on the 

rear of F4L. 

 

Use a sharp blade to score F4L along the 

broken line. 

 

Fold the bottom of F4L back against the F4L 

BRACE parts and glue it in place. 

 

Glue F2L through F10L to the crutch. 

 

Glue the VENTRAL KEEL in place on formers F2L 
through F10L. 

 

Glue F11 to the VENTRAL KEEL. Glue the two 
Horizontal Stabilizer Platforms HSP to F10U and F11. 
Sand the fuselage curvature into the HSP parts. 

 

Glue former F2A in place on the VENTRAL KEEL. Use 
a scrap of wax paper or plastic wrap between F2A and 
F2L to keep them separated. 

 

Repeat for former F4A. 

 

Dampen the wing saddles and glue them to formers 
F2L, F3L and F4L. 

 

Plank the fuselage bottom with 1/16 x 1/4 balsa strips.  
All lower planks end at the rear of F11. 

NOTE:

 As you add strips, mark each to show the dividing line 

between F2L and F2A, and F4L and F4A. Also mark 
the curve of the wing saddle on the planking. 

 

Laminate the four parts of the tail skid assembly: skid - 
skid mount - skid mount – skid. 

 

Cut slots in the ventral keel for the tail skid assembly. 
DO NOT glue the tail skid assembly in place until after 
you have covered the fuselage! 

 

Fill the lower fuselage area between F10L and F11 
with scrap 1/4 balsa.  

 

Cut the planking and keels to remove the section of 
fuselage below the wing. 

 

Laminate the two 1/16 ply wing mounts WM. Then fit 
the WM assembly into the slots in the wing saddles. 
Glue the WM assembly to the saddles and planking. 

 

Fit the wing in place on the fuselage. Drill and tap the 
mounting bolt hole. 

 

Bolt the wing to the fuselage. 

 

Carefully fit the lower fuselage section back in place, 
trimming as necessary to fit it to the wing. 

 

Cut a hole in the planking to permit access to the wing 
bolt. You can insert a rolled paper tube in this hole to 
guide the bolt. 

 

Glue the fuselage bottom to the wing. 

Cowling 

NOTE:

 The cowling is held to the fuselage by two magnets 

and two locating dowels. 

 

Glue the 1/4 NOSE SPACER blocks in place. 

 

Glue former F1 in place. 

 

Carve and sand the NOSE SPACER blocks to shape. 

 

Note the 1/8 holes top and bottom of former F1. Drill 
1/8 through these holes into the NOSE SPACER 
blocks about 1/4 inch.
