To start the build, use Foam-Tac (referred
to as FT) to glue the 4mm carbon spars
into the grooves as shown.
The plywood accessory pieces can be
spray painted to improve how the plane
looks.

Cut the fiberglass drywall tape provided in
the kit into four ¾” wide strips.
Then glue these with FT to the underside
of the wing as shown.
Assemble the plywood motor mount
pieces with CA glue.
Then glue the motor mounts to the
underside of the wing using a generous
amount of Foam-Tac as shown.
Allow this to dry for at least 30min before
further assembly.
While the motor mounts are drying, you
can solder bullet connectors to motors
and ESCs if needed.

ESCs need to be soldered together as
shown using pieces of 18 gage wire. The
length of each piece of wire depends on
how much wire comes with your esc. Once
the wires are all connected they should
measure 13” long from one esc to the
other.
Do a test of the motors and ESC’s before
gluing them into the plane to make sure
they are working properly.
If both ESCs have a BEC, then the center
red power wire must be cut or removed
from ONE of the receiver plugs. This is
done so that the receiver gets power from
only one ESC.
The nose landing gear is held in place by
gluing with FT the two plywood pieces
(one on each side) to the foam piece with
a matching hole.

The landing gear is made of 2mm wire, use
a 2.1mm drill bit to enlarge the hole in all
three wheels and the plywood wheel
collars.
Then attach the wheels to the landing gear
using the plywood wheel collars and CA
glue. Do not get glue on the wheel, it
needs to spin freely.
Use the two metal wheel collars to hold
the nose landing gear to the plywood
pieces that you glued to the nose bottom.
The wire landing gear needs to turn freely
in the plywood.
The tail booms can now be glued with FT
to the wing as shown.
Make sure that the carbon spars are facing
in towards the center of the wing!
