Recommended building methods and glues:
Much of the construction of this model is done by
laying the parts on a flat table. It is strongly
recommended that you put wax paper down on the
surface first so any excess glue doesn’t soak through
the foam and glue the parts to the table. For all
assembly, use “Welders” contact adhesive. The hinges
are also done with Welders, see our video on the web
site. Hot glue can be used to attach the servos and
control horns.
Starting out:
Look over the parts and dry fit them together to check
for proper fit.
When the spar glue is dry, hinge the ailerons to the
wing, elevator to the horizontal stabilizer and the
rudder to the vertical stabilizer.
1

The glue hinge is done with Welders glue by applying a
small bead of glue to each side of the edge of the bevel.
Spread this glue into the foam on and around the edge
of the bevel. Let the glue tack up for about a minute
and then press the parts together. Let the glue dry for
about 10 minutes and then flex the joint several times
full deflection to loosen the hinge.
Fuselage assembly:
Glue the lower fuselage to the horizontal tail. The
parts are tabbed for alignment.
Make a mark on the center of the elevator hinge line
for alignment of the fuselage sides. Glue the sides of
the fuselage to the top of the horizontal assembly. Start
at the front and work back from there being careful not
to twist the fuselage.
Glue the foam firewall doubler in place with the slot on
the bottom. Glue the plywood firewall in place.
Glue the two top fuselage pieces to the front and back
of the wing. These are also tabbed for easy alignment.
Radio and Motor Installation:
Plug all servos and speed control into the receiver.
Connect the motor wires to the speed control. These
wires need to pass through the slot in the firewall.
Attach a battery and check for proper servo centering
and motor rotation.
Glue the servos in place in the fuselage and wing. I like
to use a dab of hot glue under each mounting tab.

Lay the fuselage on top of the wing and connect the
servos and speed control to the receiver. Mount the
receiver and speed control to the sides of the fuselage.
If you need to get to them after assembly you will need
to cut a hatch to get to them.
Glue the upper fuselage and wing assembly to the
lower fuselage assembly. Again, work from the front
moving to the back and be sure to not create a bend or
twist in the finished assembly. Mount the motor to the
firewall with a couple servo screws. Cut a battery
access hatch in the top of the fuselage. Bevel the cuts
so the hatch will not fall into the fuselage. Glue in
magnets or use strapping tape to hold the hatch in
place. Apply velcro to the bottom of the forward
fuselage and to the battery to secure it in place.
Landing Gear Assembly:
Take the two pieces of 2mm carbon rod and cut a 1.5”
piece from each one. The short pieces will be the axles
and the remaining pieces will be the gear legs.
Insert the gear legs through the fuselage top corner at
the leading edge of the wing and down through the slot
in the bottom corner.
Slide the gear leg so that the end is flush with the foam
in the top corners. Do not glue them in place yet. Apply
a small drop of CA on the end of one of the axles. Hold
it in position so it is parallel with the wing. You want
the intersection of the two rods about 1/8” from the
ends. Spray with kicker to set the glue. Repeat for the
other axle.
Remove the gear legs from the fuselage. Use a 12”
piece of heavy thread to wrap the axle joint. Make half
of the wraps one direction and the other half
perpendicular to the first. Saturate the thread with CA
and then cut away the excess thread.
3

Position the gear legs back on the fuselage. Line the
axles up parallel to each other and the same height off
of the work surface. Glue them in place.
Place the wheel on the axle and slide a piece of small
fuel tubing on the end of the axle. Secure the fuel
tubing in place with a drop of CA.
Push Rod Installation:
Position control horns in place and cut a slot for the tab
to sit in. Glue in place. Line them up with the ends of
the servo arms and so the holes in the control horn are
above the hinge line.
Cut a piece of 1.5mm carbon rod for each push rod.
Cut a 1.5” long piece of 1/32” wire and make a z-bend
on one end. Slide a 1” length of heat shrink over each
end of the carbon rod and then slide in a z-bend wire.
Shrink the heat shrink tubing with a heat gun or flame.
The z-bend wire is not glued in position yet and can be
moved for final adjustments.
With the servo centered make any final adjustments to
the z-bend location. Use thin CA to secure the z-bends
to the push rods by placing a drop at each end of the
heat shrink tubing.
Center of Gravity:
3” aft of the leading edge of the wing. Built per plans
the CG should be correct.
Flight set-up:
Use your computer radio to set the final sub-trims,
exponential and dual rates. Double check the control
directions before your first flight. With proper CG,
the plane should fly nearly the same upright or
upside-down.
We have found that a 500 mah 3s battery are perfect for
giving good flight times and plenty of power as well as
a proper CG.. The final airplane weight should be
between 6.0 and 8.0 oz.
The controls can be set up with throws up to 60
degrees on all surfaces. Low rates would be 30 degrees.
We hope you enjoy your airplane.
Thank You,
