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 film. · The covering has a self-adhesive backing. Heat can be applied to shrink the covering, use indirect heat so as to not
damage the film. 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 finish. Denatured alcohol is the most aggressive agent we recommend, but test on an inconspicuous area first. Prolonged use will remove the printed detail. · Use tape with care. Anything other than low-tack tape can remove the finish, 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 finish.

FLAP HINGING
1. Remove the flap and flap 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 flap.
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 flex points to prevent adhesive from entering the hinge.
4. Check the fit of the flap to the wing using the hinges. The flap will align with the wing root. The hinge gap will be equal along the length of the flap.
Do not apply any adhesives until instructed to do so.
5. Check the gaps between the aileron and flap, and the wing root and flap. The flap will also align with the trailing edge at the aileron and wing root. The flap and wing lower surfaces will align.

CENTER OF GRAVITY
An important part of preparing the aircraft for flight 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 flying 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 flight. 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 flight-ready before balancing.
2. The overall CG range for this model is 5­6 inches (127­152mm). We recommend starting in this range, then adjusting to suit your particular flying style.
3. When balancing your model, make sure it is assembled and ready for flight. Support the plane inverted, with the landing gear extended, at the marks made on the wing with your fingers or a commercially available balancing stand.
NOSE WEIGHT
A build with typical components results in needing between 0­8 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 flights.

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.

MIXING
Flap to Elevator Compensation There is no precise number for down trim required when flaps 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 flap set at 1 inch (25mm), mix 3/32-inch (2mm) of down elevator.
With full flap set at 21/4 inches (57mm), mix 3/16-inch (5mm) of down elevator.
A flight mode setting is very useful for this aspect of setup as it allows independent trim adjustment for each flap setting in flight. This allows for in-flight adjustments and not having to land to adjust via trial and error. Most modern computer radios offer flight mode trimming.
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 flaps) 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 flying 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 fly 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 flight. 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 flying session. · All servo leads and switch harness plugs should be secured in the receiver.
