Note: (The model in this
kit has the ailerons and
elevator combined with
the tail and wing. There is
no need to bevel the
hinges.)

1.a.) In this section beveling the hinged portion of the flight controls is not required because the
hinges are incorporated in the flight controls already. Simply follow the instructions on page 7
by adding the tape to the hinge lines.
2. a.) Next cut the carbon to size for all the pre-cut slots on the tail, elevator and wing sections.
They can be cut to size with a pair of wire cutters and then have their edges sanded.
b.) Test fit the pieces and insert them into their respective locations. ( This picture does not
show the tail and elevator combined though this model does have a combined tail.)

3. a.) Once the carbon is inserted into the slot, apply painter’s tape to the opposite side ( this
applies to all the surfaces that take the carbon ). b.-d.) Then flip the surface over and remove
the carbon, leaving the tape on the surface. e.-f.) Next apply a bead of 5min. epoxy inside the
opening and push the carbon back inside wiping the residual away. After this, apply a piece of
tape on this side also. Then apply a weight on top of the surface so it will cure as flat as possi-
ble. After the epoxy cures, remove the tape from both sides and apply a small bead of epoxy
over both sides of the carbon and smear it flat so it will spread into the foam. This will bond it
into the foam better for a more rigid cure. Repeat this process at the other locations for the car-
bon.

4.a.) Once the carbon is cured it’s now time to start preparing for the taping of the hinges on the
wing, ailerons, elevator and fuselage sections. b.) First, lay the wing section and aileron bevel
side down and butt them together. Holding them together run some tape over the seam from end
to end. ( Blenderm 1” hinge tape from RCFoam ). c.) Without moving anything, flip the aileron
over onto the top of the wing and run a length of tape down the surface and cut flush with end.
d.) Now tightly wrap the tape around the surface making sure to work the tape against the foam
for a good bond. Now work the surfaces back and forth to loosen them. e.) Next insert and ep-
oxy the pin hinges in place on the vertical tail and rudder. They should already be double bev-
eled. Equally space the 3 hinges and make small marks on the tail and rudder. f.) Where the
marks are located, make a hole about a 1/2 inch deep in the center the diameter of the hinge.
When epoxying the hinges, make sure to apply a light lubricant to the center of the hinge so the
epoxy will not stick. Once dry, wipe away excess and work the surface back and forth.

5.a) Now to start the fuselage, start with the wing and lower fuselage, fitting them together with
your choice of glue such as UHU por, Beacons 3in1 or a thin bead of 5min. epoxy. b) Next glue
the upper fuselage and center section together. c) While the glue sets up make sure to have a
right angle handy to ensure the two pieces dry at a 90 degree angle so the bottom section will
line up perfectly. A piece of aluminum right angle works well because the weight helps hold it
into place. d) After the upper and center have dried the lower fuselage section can be glued on.
(Make sure to fit check everything before gluing, as this gives you an idea where to apply the
glue.)
e) Ensure to apply glue here also ( aft of the tail ). f) After applying the glue, slide the lower fu-
selage section into place and then apply blue 1” painter’s tape to the top nose area and tail sec-
tion to keep them tight and aligned.

6.a) While the fuselage is drying the motor mount can be installed. b) Make sure to install the
motor mount at 90 degrees to the fuselage in all directions. This will determine the plane’s an-
gle of attack flying. c) Because this is a critical area for torque, bond this area with 5min. epoxy
or better. Apply the epoxy everywhere the mount contacts the foam for a good bond, this also
helps align the nose. d) Now bond the wing everywhere it touches the fuselage. A thin bead of
epoxy is recommended or the other glues mentioned previously. e) Now install the 2mm De-
pron on the leading edge, (there are 4 pieces included in the kit). This is done by using a spray
glue such as the 3M 27. f) Applying the 2mm Depron on the leading edge changes the effect of
the wing, giving it more of an airfoil effect. This is optional. Just trim to fit on the upper and
lower surfaces and spray glue in place, then sand to fit.

The next few pictures indicate where the components are lo-
cated on the prototype. Painting is done with an acrylic based
craft paint sold at RCFoam. The center of gravity is located at
the wing spar or just a little aft. This is the ideal location for
performance.
