Where a part must be glued during assembly to an area 
that has been covered with tissue, trim away the tissue 
so that there is wood-to-wood contact in the joint. Glue 
wing and tail on lightly at several spots only so that the 
joints will separate in a hard landing without damaging 
the structure. 
 
You can now cement the wing to the fuselage. After the 
wing is installed the top three fuselage stringers are 
added. Paint the area behind the windshield gray and 
add the instrument panel. Install the windshield struts 
which are also painted gray. You can make gray by 
mixing a little black in some white paint. Now cut out the 
plastic windshield and carefully try it for fit. Trim where 
necessary. Use a small amount of Sig-Ment or Contact 
Cement to attach. Extreme care should be exercised to 
keep cement from blemishing the windshield. You can 
now finish covering the wing center section and top of 
the fuselage. Next install the tail surfaces. After the 
stabilizer is cemented into its slot in the fuselage cover 
the open part of the slot with a small piece of tissue. Be 
sure that the tail looks straight with the wing when 
sighting from the front of the airplane. 
 
Spray the tissue with a light coat of water. A sprayer 
from a window cleaner or a liquid household cleanser 
works well. This will tighten the tissue. When dry give the 
airplane a single coat of clear dope. 
 
It is likely that some warps will appear and these are 
easily removed by twisting the warped surface opposite 
from the warp while holding over the spout of a steaming 
tea kettle. Wear gloves as steam can give nasty burns. 
 
Add strut attach fitting to underside of the wings. Trim 
struts to proper length and install. The struts will prevent 
further warping of the inboard part of the wing, but if the 
wing is warped before you install the struts it will be 
impossible to remove the warp without first taking off the 
strut. 
 
Cement the cowl in place on front of fuselage. Add the 
landing gear strut fairings, wheels and wheel pants. The 
fairings and pants are painted after installation. 
 
To make a more attractive model vou can add outlines of 
the control surfaces, doors, lights, etc. This can be done 
with India ink and a drafting pen or with thin strips of 
black tissue. When the markings are done apply another 
coat of clear dope to the tissue covered areas. Now add 
the decals to the places shown on the plan. Refer to the 
pictures of the model for additional help on decal 
location. Exhaust stacks can be made from paper tubes 
painted gray. The rigging on the tail is made of gray 
thread. 
 
The nose plug is made of laminated parts P1 and P2. 
When cementing them together make sure the grain 
runs in opposite directions on alternate pieces. The hole 
through the center can be made with a 1/16" drill or a 
large needle. Round the front of the plug with 
sandpaper. Cement the eyelets in place, preferably with 
epoxy glue. Finish the nose plug in the same manner as 
the cowl and paint gray or dark blue. Install propeller 
hook, bead, and plastic propeller.
