Great Planes Spirit 2-Meter Sailplane Kit - GPMA0530 - Manual (Page 19)

these sheets to match the contour of the wing and be careful
not to add much to the wingspan with these extra sheets.
D 30. Sand three edges (two short and one long edge) of
each 1/16" Plywood Wing Protector (SPRTW18) to a taper
as shown on the plans and glue them in place on top of each
trailing edge. They should be oriented so the unsandcd edge
is flush with the back of the trailing edge and they should be
placed 9/16" away from the root of the wing. These will
protect the wing trailing edge from being dented.
Wing Protectors
FUSELAGE ASSEMBLY
D 26. Drill a 1/16" hole in each 1/16" Die-Cut Plywood
Spoiler Horn (SPRTW05) at the indentation. Cut a 1/16"
wide slot in the spoiler for the spoiler horn using a razor saw
(a hack saw blade will also work fine) and glue the horn in
place. It should be flush with the top surface of the spoiler as
shown on the plans. This completes the assembly of the
spoilers until after the wing is covered.
D 27. Assemble the spoiler on the other wing panel.
STEPS 28 AND 29 APPLY TO ALL WING
CONFIGURATIONS.
D 28. Use the remaining piece of 1/16" balsa sheeting to
sheet the top inboard center section out past rib W1B as
shown in the photo. Thick CA should be used for this step.
Pre-cut the sheeting to fit first near the spars, and cut a second
piece to fit between the first piece and the trailing edge. Glue
these in place and if you built a two-piece wing, sand the
sheeting flush with the W1A and W1B ribs at the wing root.
D 29. If you built a two-piece wing, trial fit the two wing
halves together using the plywood wing joiner. Sand the root
of each panel if necessary to achieve a nice close joint
between the two wings. If there are large gaps, glue a sheet
of 1/16" balsa to the root of the panels to fill the gaps. Sand
You'll need the following items:
SPRTF01 3/32" Balsa Fuselage Sides, Wing Saddle Tripler
SPRTF02 3/32" Balsa Fuselage Doublers
SPRTF03 1/8" Plywood From Fuselage Bottom
SPRTF04 1/16"
Balsa Rear Fuselage Sheeting
SPRTF05 1/8" Plywood Formers
SPRTF07 1/8" Square x 24" Balsa Stringer
SPRTF08 3/16" x 30" Balsa Triangle
SPRTW05 1/16" Plywood Towhook Plate
ASSEMBLE FUSELAGE SIDES
D 1. Pin or tape the fuselage plan to your flat work
surface and cover it with waxed paper. Pin one of the 3/32"
Die-Cut Balsa Fuselage Sides (SPRTF01) down ABOVE
the FUSELAGE SIDE VIEW so you can use the plan for
reference. This is going to be the LEFT fuselage side.
DD 2. Trial fit one of the 3/32" Die-Cut Balsa Front
Fuselage Doublers (SPRTF02) onto the 3/32" Balsa Fuse-
lage Side. The doubler should line up with the fuselage where
the canopy will sit. The arrows in the photo point out this
area. Spread a thin layer of thick CA on the doubler and glue
it to the fuselage side.
