This is how your kit will arrive
When cutting the hardware package open use caution. The contents are
semi-coiled to fit in the box. They will spring open very quickly. You also
want to avoid cutting or losing any of the parts in the bag. Safest
method is to slide the carbon out one at a time, leaving the bag coiled.
All kits come with motor mount tube and screws. A poly-card with the
needed control horns (and other poly parts if needed) Heat shrink
tube(self adhering) for control horns (do not use CA with this). Wire for
z-bends is also included. Ohh, and lots of carbon fiber.
A simple and very effective
method to prevent epp hinge
failure is to glue in fishing line. A
shallow slot is cut across hinge
line and a piece of fishing line is
inserted. Do this at both ends of
the hinge and at control horn.
It is possible to use many other
filaments. Various threads work
well, nylon, kevlar, etc. If using CA
be careful to avoid the glue
wicking into the pivot. Filament
packing tape also works very well
Notches will help lineup parts. Most
builders have a glue preference. Many
glues will work well for this.
Horizontal nose, midsection, wing panels
and elevator assemblies can all be glued
up with parts lying flat on build table. Only
thing to watch for is to not fill carbon slots
with glue.
The rectangular recess pockets are for
mounting servos. The servo arm should
pass through the corresponding slots.
Wing carbons are 6mm x
1mm x 35-1/4”in the rear
and 6mm x 1mm x 33-7/8”
for the front spar. Test fit the
carbon after cutting to
length, then glue.
Aileron counterbalance
carbons are 2mm rod 2 3/4”
long. Elevator carbon is
6mm x 1mm x 13-1/4”.
Weighting the assembly to
hold assembly flat while all
glue dries can help insure a
flat build.
Glue lower side of vertical fuselage to bottom. Foam can be slightly stretched and
compressed to fit into notches. Glue a small area at a time while checking for square with
square scrap foam supplied with kit.
Be sure the assembly lies flat and does not lift off the table anywhere. If it does not lay flat,
move the lower fuselage until the plane will lay flat before gluing.
Carbon can now be added for landing gear legs, (2) 6mm x 1 mm x 9-1/2” long. A notch is
provided in front of wing and a slot is precut for intersecting point in vertical fuselage. These
are glued into place at notches and intersecting point being sure to pull carbon up away
from table to top of slot.
Install the formed
plastic parts. Cut
the formed plastic
into sections that
fit onto the bottom
of the wheel
section of the
wheel pant foam.

Start by threading carbon through center of vertical fuselage and then into wing. After getting
location established, pull out and add drop of hot glue to each end of carbon. Reinsert while
twisting the carbon truss. This will drag glue down into hole with carbon and makes for a strong
and clean install.
The 1mm rods that meet at the gear leg intersection should touch the gear legs. This will help
strengthen by reducing the force the foam absorbs.
5-¼”
Top side of fuselage can now be installed. Same way as bottom being careful to fit snug
into slots and squaring with horizontal while gluing. Back will wrap around elevator and
meet up with underside.
Prepare for electronics by cutting the
z-bend wire into (8) equal lengths. Also
cut the poly mount tubing into (4) equal
lengths.
Now plane can be turned over on the
workbench to check for level. Gear legs
can be shortened until the wing is
parallel with work surface.
