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 sufcient 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, y the helicopter when the air temperature is above 50 degrees Fahrenheit. The Arrowhead is powered
by a lithium polymer battery that suffers signicantly decreased performance at low temperatures. Avoid locations exposed
to wind, otherwise the helicopter may become uncontrollable. Do not y 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 ight.
• Adult supervision is required when children 14 and under are ying 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 ying 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 y correctly if broken. If, after a repair, the helicopter wants to y 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 y forward and won’t stop going forward, tape a very small weight to the tail.
