BUILDING PRECAUTIONS
Prepare the work surface prior to beginning the build. The surface should be soft and free of any sharp objects. We
recommend resting the airframe parts on a soft towel or pit mat to prevent scratching or denting the surface of the
aircraft.
TRANSPORTATION AND STORAGE
Use the three-view drawing on page 90 to determine how much room will be required to transport and store your
model. We also recommend the use of wing and stabilizer bags to help protect these surfaces during transport and
storage. The control horns and linkages can cause damage to other surfaces even when placed in storage bags.
Always transport and store the wings and stabilizer so the linkages do not contact other panels to prevent damage.
CHECKING BLIND NUTS
When building the aircraft, you will be required to thread machine screws into blind nuts. We recommend pre-threading
the screws to make sure the blind nuts are clear of any debris. If the screws do not thread in easily, clear the threads
using the appropriate tap and tap handle.
PRINTED COVERING NOTES
• The covering used on your model has the color and markings printed directly on the fi lm.
• The covering has a self-adhesive backing. Heat can be applied to shrink the covering, use indirect heat so as to not
damage the fi lm. Use a covering iron on low and place a piece of parchment paper or covering backing between
the model and covering iron to disperse the heat. A heat gun can also be used to shrink the covering. Apply heat
sparingly (2-3 seconds), and use a glove to press the covering into concave areas.
• Use only mild cleaning agents on the printed fi nish. Denatured alcohol is the most aggressive agent we recommend,
but test on an inconspicuous area fi rst. Prolonged use will remove the printed detail.
• Use tape with care. Anything other than low-tack tape can remove the fi nish, particularly on edges.
• Avoid contact with raw fuel. Prolonged exposure to fuel or chemicals may damage to the printed covering.
• Remove exhaust residue as soon as practical to avoid staining or damaging of the fi nish.

FLAP HINGING
1. Remove the fl ap and fl ap hinges from the wing panel.
The hinges are not glued to the wing or flap.
Optional: Apply a piece of white covering
for a more finished appearance.
2. Use a hobby knife and covering iron to seal the covering into
the recessed control horn mounting area on the leading edge
of the fl ap.
3. Check the hinges to make sure they operate freely. Adjust the
tension of the screw if any hinges do not move freely. Apply
a small amount of petroleum jelly to the hinge fl ex points to
prevent adhesive from entering the hinge.
4. Check the fi t of the fl ap to the wing using the hinges. The
fl ap will align with the wing root. The hinge gap will be equal
along the length of the fl ap.
Do not apply any adhesives until instructed to do so.
6. Remove the fl ap and hinges. Inject adhesive into each of the
hinge pockets of the fl ap.
Deluxe Materials Aero Tech Epoxy
(DLMAD64) is recommended.
7. Inject adhesive into each of the hinge pockets of the wing.
8. Apply a small amount of adhesive to each hinge where it will
enter the fl ap and wing.
5. Check the gaps between the aileron and fl ap, and the wing
root and fl ap. The fl ap will also align with the trailing edge at
the aileron and wing root. The fl ap and wing lower surfaces
will align.

isopropyl alcohol to remove any excess epoxy. Allow the
epoxy to cure, then remove the tape.
21. Fit the assembly into the slots in the aileron.
22. Place low-tack tape around the control horn base. This will
help keep excess epoxy off the aileron.
23. Remove the assembly and mix 1/2 ounce (15ml) of 30-minute
epoxy. Apply epoxy in the control horn slots.
26. Hinge the ailerons using the same technique outlined for the
fl ap hinges. Make sure the aileron is aligned with the fl ap.
27. Make sure hinge gap is consistent along the entire length of
the aileron. Use low-tack tape to hold the aileron in position
until the adhesive has fully cured.
Trial fitting the tip tank at this stage allows for the
installation of the aileron and verification that the
aileron will not come in contact with the tip tank.

CENTER OF GRAVITY
An important part of preparing the aircraft for fl ight is properly balancing the model. The Center of Gravity range
supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result
in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment
with different balance points. We advise adjusting progressively and cautiously.
1. Assemble the model and ready it for fl ight. Make sure to connect the leads to the appropriate leads from the
receiver. Make sure the leads are not exposed before tightening any hardware. Your model should be fl ight-ready
before balancing.
2. The overall CG range for this model is 5–6 inches (127–152mm). We recommend starting in this range, then
adjusting to suit your particular fl ying style.
3. When balancing your model, make sure it is assembled and ready for fl ight. Support the plane inverted, with the
landing gear extended, at the marks made on the wing with your fi ngers or a commercially available balancing
stand.
NOSE WEIGHT
A build with typical components results in needing between 0–8 ounces of nose weight.
The model is most accurately balanced inverted.
CAUTION: You must adjust your aircraft’s center of
gravity and balance your model properly before attempting fl ights.
CONTROL THROWS
1. Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter.
When the stick is moved to the right, the rudder should also move right. Reverse the direction of the servo at the
transmitter if necessary.
2. Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the
transmitter will make the elevator move up.
3. Check the movement of the ailerons with the radio system. Moving the aileron stick to the right will make the
right aileron move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons and rudder.

There is no precise number for down trim required when fl aps are applied. This can vary slightly from plane to plane
and personal preference. Use the measurements provided as a starting point and adjust as necessary.
With partial fl ap set at 1 inch (25mm), mix 3/32-inch (2mm) of down elevator.

With full fl ap set at 2
A fl ight mode setting is very useful for this aspect of setup as it allows independent trim adjustment for each fl ap
setting in fl ight. This allows for in-fl ight adjustments and not having to land to adjust via trial and error. Most modern
computer radios offer fl ight mode trimming.
/4 inches (57mm), mix 3/16-inch (5mm) of down elevator.
PREFLIGHT CHECKLIST
• Charge the transmitter, receiver, retract and ECU batteries. Follow the instructions provided with the charger. Follow
all manufacturer’s instructions for your electronic components.
• Check the radio installation and make sure all control surfaces (aileron, elevator, rudder, and fl aps) move correctly
(i.e., the correct direction and with the recommended throws).
• Check all the hardware (control horns, servo horns, and clevises) to make sure they are secure and in good condition.
• Prior to each fl ying session (and especially with a new model), perform a range check of your radio system. See your
radio manual for the recommended range and instructions for your particular radio system.
DAILY FLIGHT CHECKS
• Check the battery voltage of the transmitter battery. Do not fl y below the manufacturer’s recommended voltage.
Doing so can cause your aircraft to crash.
• Check all hardware (linkages, screws, nuts, and bolts) prior to each day’s fl ight. Ensure that binding does not occur
and that all parts are properly secured.
• Ensure all surfaces are moving in the proper manner.
• Perform a ground range check before each day’s fl ying session.
• All servo leads and switch harness plugs should be secured in the receiver.
