Flying Tips and Repairs

We recommend fl ying your aircraft indoors in a
gymnasium, or outdoors in calm conditions. Always
avoid fl ying near houses, trees, wires and buildings.
You should also be careful to avoid fl ying in areas
where there are many people, such as busy parks,
schoolyards or soccer fi elds. Consult local laws and
ordinances before choosing a location to fl y your
aircraft.
NOTICE: Always launch the aircraft in General Flight
or Standard AS3X ® mode or damage to the aircraft
may result.
Takeoff
Place the aircraft in position for takeoff (facing into
the wind if fl ying outdoors). Set dual rates to low
position and gradually increase the throttle to ¾ to
full and steer with the rudder. Pull back gently on
the elevator and climb to check trim. Once the trim
is adjusted, begin exploring the fl ight envelope of
the aircraft.
Failure to lower the throttle stick and trim to the
lowest possible positions during a crash could result
in damage to the ESC in the receiver unit, which
may require replacement.
Over Current Protection (OCP)
This aircraft is equipped with Over Current
Protection (OCP). This feature protects the ESC
from overheating. OCP stops the motor when the
transmitter throttle is set too high and the propeller
cannot turn. The OCP will only activate when the
throttle stick is positioned just above 1/2 throttle.
After the ESC stops the motor, fully lower the
throttle to re-arm the ESC.

Post Flight Checklist


1. Disconnect the flight battery from the
ESC (Required for safety and battery
life).
2. Power OFF the transmitter.
3. Remove the flight battery from the
aircraft.
4. Recharge the flight battery.
NOTICE: Crash damage
is not covered under the
warranty.
Repairs
Repair the aircraft using
foam-compatible CA
(cyanoacrylate adhesive) or
clear tape. Only use foam-
compatible CA, as other
types of glue can damage
the foam. When parts are
not repairable, see the
Replacement Parts List for
ordering by item number.
For a listing of all
replacement and optional parts, refer to the list at
the end of this manual.
NOTICE: Use of foam-compatible CA accelerant on
your aircraft can damage the color printing on the
fi lm. DO NOT handle the aircraft until the accelerant
fully dries.
IMPORTANT: The fi lm on the aircraft may show
wrinkles. Wrinkles vary with the passage of time
and do not change the aircraft's fl ight performance.
NOTICE: When you are fi nished fl ying, never leave
the aircraft in direct sunlight or in a hot, enclosed
area such as a car. Doing so can damage the
aircraft

5. Store the flight battery apart from the
aircraft and monitor the battery charge.
6. Make note of the flight conditions and
flight plan results, planning for future
flights.
