V. FLIGHT LOCATION
AND CONDITION
Flight Location
Check that there are no obstacles around the flight location before flying the helicopter.
• Fly the helicopter in a safe area away from roads, other persons and animals, trees, buildings, overhead power lines and
other obstacles.
TROUBLESHOOTING GUIDE
Check the following items if your Arrowhead is not operating properly:
• Make sure the power is on.
• Make sure the main battery and the transmitter battery have sufficient charge.
• Check if the main battery and the transmitter battery are inserted with correct polarity.
• Check if the antenna of the transmitter is broken.
• Check if the distance between the transmitter and the helicopter exceeds 20 meters.
• Check if a nearby transmitter produces interference or signals on the same frequency.
Unlike other radio control helicopters, the AH-78 Arrowhead has a number of replacement parts available in the event of
damage. These parts are easily replaced with common household tools, and should be available at any hobby store that
carries SPARC!™ products.

Flight Condition
For best performance, fly the helicopter when the air temperature is above 50 degrees Fahrenheit. The Arrowhead is powered
by a lithium polymer battery that suffers significantly decreased performance at low temperatures. Avoid locations exposed
to wind, otherwise the helicopter may become uncontrollable. Do not fly the helicopter in bad weather (heavy thunderstorms,
rain, sleet, snow, etc.).
Important:
• ensure that a nearby transmitter does not produce interference or signals with the same frequency.
• Always supervise the helicopter in flight.
• Adult supervision is required when children 14 and under are flying the helicopter.
• The helicopter is intended for outdoor use.
VI. MAINTENANCE
Care and Service
• The life of the helicopter can be extended with daily care. Keep the Arrowhead clean, and check for damage and loose
parts after every flying session or after a crash.
• The helicopter body is made of polystyrene foam. If damaged, use clear tape or a suitable adhesive to repair. Foam-safe
CA can be purchased from your local hobby shop.
• Never use instant glue, which will make the polystyrene foam dissolve.
• The helicopter may lose balance and not fly correctly if broken. If, after a repair, the helicopter wants to fly backward, try
taping a small amount of weight under the nose of the helicopter, or use a small wad of modeling clay. Likewise, if it wants
to fly forward and won’t stop going forward, tape a very small weight to the tail.
