as shown on the plans and glue them in place on top of each
trailing edge. They should be oriented so the unsanded edge
is flush with the back of the trailing edge and they should be
placed 9/16" away from root of the wing. These will protect
the wing trailing edge from being dented by the rubber bands. holes, about 1/2" apart, where the black dots are in the photo
and apply a couple of drops of thin C/A to each hole. The thin
C/A will soak into the wood and provide a good bond.
FUSELAGE ASSEMBLY
You'll need the following items:
SPECF01 3/32" Balsa Fuselage Sides and Wing Saddle
Tripler
SPECF02 3/32" Balsa Fuselage Doublers
SPECF03 1/8" Plywood Front Fuselage Bottom
SPRTF04 1/16" Balsa Rear Fuselage Sheeting
SPECF05 1/8" Plywood Formers
SPECF07 1/8" Plywood Formers
SPECP08 3/16" x 15" Balsa Triangle
SPECF13 1/16" Balsa Nose Cap and Rear Doubler
SPECF15 Balsa Top Nose Block
DOWEL030 1/4" Hardwood Wing Dowel
DD 3. Glue the 1/16" Die-Cut Balsa Rear Fuselage
Doubler (SPRTF13) in place making sure it lines up with the
fuselage side. Use a T-pin to poke holes where the black dots
are in the photo and put a couple of drops of thin C/A in each
hole and around the edges.
ASSEMBLE FUSELAGE SIDES
D 1. Pin or tape the fuselage plan to your flat work
surface and cover it with waxed paper. Lay one of the 3/32"
Die-Cut Balsa Fuselage Sides (SPECF01) down ABOVE
the FUSELAGE SIDE VIEW so you can use the plan for
reference. This is going to be the LEFT fuselage side.
DD 4. Glue one of the 3/32" Die-Cut Balsa Wing Saddle
Triplers (SPECF01) in place on top of the front fuselage
doubler. The tripler should be flush with the top of the
doubler but do not let it overlap the notches for the formers.
Sand the edges of the doublers/tripler flush with the edge of
the fuselage side.
DD 2. Trial fit one of the 1/16" Die-Cut Balsa Front
Fuselage Doublers (SPECF02) onto the 3/32" Balsa Fuse-
lage Side. Line up the doubler so the edges of it are even with
the edges of the fuselage side (except the front). Note that the
doubler is 1/8" shorter in front than the fuse side. It is
important to get this doubler properly aligned since all of the
formers will key into it. With the doubler in place, apply thin
C/A around all edges and cutouts. Use a T-Pin to poke a few
D 5. Go back to step 2 and assemble the RIGHT fuselage
side. The easiest way to do this is to lay the other fuselage side
upside down below the one you just built as shown in the
photo. MAKE SURE YOU ARE NOT BUILDING TWO
IDENTICAL SIDES, THEY SHOULD BE THE OPPO-
SITE OF EACH OTHER.
