Wing
Basic assembly methodology. When assembled on a flat work surface, this wing will jig together and self align to create
one of the straightest wings you have ever built. Each part relies on the successive component to achieve this; we
suggest that you rely on friction and the interlocking construction to hold the wing together throughout the building
process, hold off on the CA glue until you are directed to use it– this allows the individual components to shift and align as
each part is added – once all the pieces are in-place the assembly will be pulled together straight and true.
1.
Begin wing construction by locating and joining together the following sub-assemblies with thin CA:
S1 Main Spar (1)
From
S1A, S1B, S1C
(1/16” Balsa)
S2 Spar Cap Upper (1)
From
S2A, S2B, S2C
(3/32” Balsa)
S3 Spar Cap Lower (1)
From
S3A, S3B, S3C
(3/32” Balsa)
L1 Leading Edge Jig (2)
From
L1A, L1B
(1/16” Balsa)
L2 Leading Edge Cap (2)
From
L2A, L2B
(1/8” Balsa)
T1 Trailing Edge Jig (2)
From
T1A, T1B
(1/16” Balsa)
T2 Cap Strip (4)
From
T2A, T2B
(1/16” Balsa)

2.
Locate ribs R1 (1/8”) and R2 (3/32”) and CA the cross bracing in place in the notches provided just aft of the
ribs mid section. The cross braces are located within the respective rib lightening hole on the cut wood sheets.
3.
At this point it is a very good idea to lightly sand both sides of the wing ribs and spar. It is also a good time to
consider lightly sanding the burn marks from the edges of the ribs – be very gentle as the assembly is quite
delicate at this point.
