2.3 Locate the 6-mil Wing Saddles and trial fit them to the wing saddle area on both sides of the fuselage. Align the
punched out holes and the wing saddle itself. When satisfied, using contact cement, glue the wing saddles to the fuselage
rail doublers.
2.4 Locate 4-mil thick Bulkheads A,B, & C. Carefully remove them from their trim using a hobby knife. Note that the bulkheads
have two sets of prepunched holes. The COLT uses the lower set of holes that are shown in the illustration so that the control
rods will exit nearest the wing into the radio compartment. Trim and clean the prepunched holes for control rods.
2.5 Mark and fit the bulkhead locations. Bulkheads A, B and C have "ears" or tabs on them designed to fit into the
slots found in the fuselage doublers you just installed. Note that the control rod holes for bulkheads A through C that you
will use should be nearest the bottom of the fuse.
2.6 Locate the two 27" long steel push rods (threaded on one end) in the kit, and run them through the push rod holes
in bulkheads A-C, with the threaded end of the push rod at the rear of the airplane. Note that the rods need to exit Bulkhead
A into the radio compartment toward the bottom of the fuse. Remember that the bottom of the fuse is facing you, and the
top of the fuse is on your work table. Space the bulkheads appropriately along the push rods and position them in the fuse
where their tabs will fit into the notches. Wrap some tape around the ends of the rods to keep them from falling out of the
holes in the bulkheads. Test-fold the fuselage around the bulkheads and make sure everything fits well. Trim the bulkheads
if necessary to obtain a square, snug fit for all parts. Finally, coat the edges of the bulkheads and their slots with contact
cement in preparation for final fold-up.
BUILDER'S HINT - IF YOU WOULD LIKE TO "CONCEAL" YOUR RADIO ANTENNA WIRE INSIDE THE FUSELAGE, PURCHASE A LIGHT WEIGHT, 24"
LONG PIECE OF PLASTIC (NON-METALLIC) TUBING AND INSTALL IT THROUGH THE BULKHEADS BY DRILLING A HOLE IN EACH BULKHEAD OFF-
CENTER, BETWEEN AND ABOUT 1/2" BELOW THE LOCATIONS OF THE CONTROL ROD HOLES. WHEN YOUR PC IS INSTALLED IN THE MODEL, THE
ANTENNA CAN BE PASSED THROUGH THIS "TUBE" AND HIDDEN INSIDE THE MODEL!
2.7 Trial fold the fuselage. Note that the fuselage bottom flaps are arranged so that one side consists of "inside" flaps
and the other side is "outside" flaps. Trial fold the fuse to check that everything is folding up square and that the slots in the
rear bottom of the fuselage line up for fin placement later. You might hold it together with a little masking tape just to
"eyeball" it. The top of the fuse should lay flat on your work surface when folded up. We've found that moving the front and
back bottom flaps around a little and repositioning them will cure any "squaw." Also remember that the inside flaps fold in
first on the fuse. The flaps are sized for this purpose. When gluing, we will fold the rear flaps first, and the nose flaps last.
2.8 Assemble the fuselage. YOU MAY NEED ASSISTANCE WITH THIS STEP FIRST FOLD THE REAR FLAPS, AND THEN THE FRONT FLAPS.
Using contact cement, liberally coat the fuse flaps where they will make contact. (BE SURE TO REMEMBER "INSIDE"VS "OUTSIDE" FLAPS
AND GLUE THEM ACCORDINGLY). Go ahead and completely coat the appropriate surface of each fuse flap, not just the edges, as you
want a firm bond along the bottom of the fuse. Also prepare and insert your bulkheads with control rod housings in place for final
fold-up. DO NOT GLUE THE CONTROL RODS TO THE BULKHEADS AT THIS TIME. When ready (don't rush the cement) and still on a flat work
surface, fold up the fuse first around the bulkheads, then the nose, while applying pressure for a good bond.
