Glue main fuse top, and top rear doubler/stab platform in

place, and let fuse dry thoroughly. 

Note: 

Stab platform

fits 

between 

the fuse sides.

10.    

 

 

Remove fuse from work surface, and glue 1/16” ply 

bottom and main balsa bottom in place. If necessary,
spread  sides in the hatch area to match the width of the
1/16” ply  bottom.

 

 

From plan, locate the correct position for 1/8” ply tow hook

doubler, and glue securely in place inside fuse.

11.   

 

 

From 1/8” square balsa cut two wing rails, and glue to 
fuse sides as shown on plan. 

Note: 

front end of rails is 

tapered.

 

 

Temporarily tack-cement hatch in place (it must be 

removed later!)

 

 

Glue nose block to fuse front (unless, of course, you 

intend to mount an engine there! In that case see next 
step).

NOSE-MOUNTED ENGINE OPTION

12.  

 

 

Remove tank and rotate it 90 degrees so you can side-

mount engine. Side-mounting helps to keep gunk off
model.

 

 

Center engine on 1/8” ply mount. Mark and drill 3/32”

holes for engine mounting screws.

 

 

Install engine on mount using screws, washers and nuts as

shown on the plan. Press mounted engine in position to 
impress nut locations into former 1. Make recesses in
former 1 for nut clearance.  

 

 

Gently sand fuse front to remove rough spots. Securely

glue engine mount to fuse front. Let dry.

 

 

Remove engine for easier sanding of fuse.

13.    

 

 

From 1/16”x3”x18” balsa, cut rear top and bottom sheet-

ing

(grain running across fuse). Glue sheeting in place.
