Fuselage (Glider Version)
• Trial fit the parts of the fuselage– no glue yet! Sand as
necessary to obtain perfect fit (Fig. 5)
• Glue the ply reinforcement and balsa triangle stocks
to the fuselage sides. Glue together the canopy. Glue
the canopy magnets before final sanding; please do
not forget to check and mark the polarity of magnets
first – they must attract each other. (Fig. 6+7)
• Glue together the front part of the fuselage; do not
forget to sand the edges of the formers to the shape.
(Fig. 8)
• Epoxy the wing nut plate with nuts already glued
and the tail boom holding formers in place (Fig. 8)
• Glue the upper and lower sheeting of the fuselage;
do not forget to epoxy the tow hook plate. (Fig. 9)
• Glue the nose cone parts in place and sand them to
the required shape using the supplied template. (Fig.
9)
• Slide the carbon fairing and the ply fairing former
onto the carbon tube tail boom. Insert the tail boom
into the fuselage (no glue yet – it will be glued only
after the final sanding and covering of the fuselage).
Trial fit all the parts and sand carefully to obtain a ti-
ght fit; the fairing matching the rear edge of the fu-
selage. (Fig. 10)
• Attach the canopy to the fuselage and sand eve-
rything smooth. (Fig. 9+11)
• Locate the towhook; cut the opening for it in the
lower part of the fuselage and drill the holes for the
fixing screws. (Fig. 12)
Fuselage (Electric Version)
• The building sequence of the electric version fuse-
lage is basically the same as with the glider version
except for the firewall and nose. Epoxy the firewall in
place and sand the nose to the desired shape using
the round jig inserted into the firewall. (Fig. 13-15)
• Before you epoxy the firewall in, make sure the ope-
nings and holes in the firewall match your motor –
make any changes as necessary or cut a new firewall
to match your motor perfectly. (Fig. 13)
Wing
Wing Centre Section
• Epoxy together the wing central ribs; insert 3 mm
beech dowels into the holes in order to obtain co-
rrect match. Note: Make a left and right pair of ribs.
(Fig. 16+17)
• Epoxy the wing fixing bolt plate between the central
ribs. (Fig. 18)
• Epoxy together the parts of the main spar shear web-
bing; the short 0.8 mm ply joiner (with a hole in the
centre) to the front side, the long joiner to the rear
side. Make bays for the wing carbon joiner; epoxy
together front (shorter) 0.8 mm ply plate, 5 mm ply
central plate and rear 0.8 mm ply (longer, slanted
edge) plate. Prevent the epoxy hardening inside the
bays – put the parts together with the carbon joiner
inserted, then immediately remove the joiner (do not
forget cleaning the joiner using a paper tissue and
rubbing alcohol before the glue sets). (Fig. 19-22)
• Slide all ribs onto the mains spar shear webbing (no
glue yet!). Bind the joiner bays with the provided Ke-
vlar thread and soak with medium CA. (Fig. 23+24)
• Insert the rear spar, trial fit the leading and trailing
edges. Sand to fit if necessary. Once satisfied with the
fit, glue all the parts of the wing centre section with
medium cyano over the building plan protected with
a sheet of thin clear plastic film (you might find better
gluing ribs to the main spar shear webbing with an
aliphatic resin). (Fig. 25-27)
• Glue the lower 8x2 mm spruce stick main spar in place.
• Edge glue together the upper D-box sheeting (1.5
mm balsa) and the upper 8x2 mm spruce stick main
spar; once cured glue it to the wing using aliphatic
resin. (Fig. 28-29)
• Bevel both two end ribs of the wing centre section
using the supplied 7° dihedral jig. Then glue the 3
mm liteply end ribs with magnets. (Fig. 30)
• Glue the airbrake frame to the upper side of the wing
and sheet the space between the central ribs with 1.5
mm balsa. Cut the openings for the wing fixing bolts.
(Fig. 31)
• Epoxy the central half rib with the wing alignment
pin and sheet the space between the central ribs
with 1.5 mm balsa. Cut the openings for the wing
fixing bolts. (Fig. 32)
• Glue the reinforcements square to the 2.5 mm balsa
airbrake. (Fig. 33)
• Fine sand the entire wing centre section (incl. the
airbrake).
Wing Outer Panels
• The wing outer panels are to be constructed in the
same manner as the wing centre section; the main
difference is that the inner part and the outer win-
glet are built as one part on a flat surface. Once the
structure is finished, you will cut it between the end/
root ribs, bevel to obtain the correct dihedral and
glue together. (Fig. 34+35)
• Glue together both two wing outer panels over the
building plan protected with a sheet of thin clear
plastic film (remember – you are building left and
right wing panels!).
• Glue the wing tips; bevel the ends of the main spar
sticks and glue them to the wing tips. (Fig. 36+37)
• Glue 2.5 mm balsa triangular wing gussets. (Fig.
38+39)
• Fine sand the entire wing outer panels.
• Cut off the outer winglets between the end ribs; be-
vel the end ribs using the supplied 8° dihedral jig.
(Fig. 40)
• Epoxy the wing panels and winglets together. (Fig. 41)
