Flying Tips and Repairs
Consult local laws and ordinances before choosing a fl ying location. 
Flying Field
Always choose a wide-open space for fl ying your aircraft. It is recommended 
that you fl y at a designated RC fl ying fi eld. Always avoid fl ying near houses, 
trees, wires and buildings. Avoid fl ying in areas where there are many people, 
such as parks, schoolyards, or soccer fi elds. 
Range Check your Radio System
Before you fl y, range check the radio system. Refer to your specifi c transmitter 
instruction manual for range test information.
Understanding Oscillation
Once the AS3X system is active (after advancing the throttle for the fi rst time), 
you will normally see the control surfaces react to aircraft movement. In 
some fl ight conditions, you will see oscillation. If oscillation occurs, decrease 
airspeed. If oscillation persists, refer to the Troubleshooting Guide for more 
information.
Takeoff
Place the aircraft in position for takeoff (facing into the wind). Set your
transmitter to low rate and gradually increase the throttle from 60% to full 
and steer with the rudder. As the airplane gains speed, gently pull back on 
the elevator and climb to a comfortable altitude. You may also set fl aps to half 
travel for shorter takeoffs.
Flying
Fly the airplane and trim it for level fl ight at ¾ throttle with fl aps up. After 
adjusting trim in fl ight do not touch the control sticks for 3 seconds. This allows 
the receiver to learn the correct settings to optimize AS3X performance.
Landing
Make sure to land the aircraft into the wind. Start to slow the model down to an 
approach speed and set the fl aps to half travel. If landing in windy conditions, 
land at half fl ap travel. If fl ying in light winds, set fl aps to full for fi nal approach.
With fl aps, fl y the aircraft to approximately 36 inches (90 cm) or less above 
the runway, using a small amount of throttle for the entire descent. Keep the 
throttle on until the aircraft is ready to fl are. During fl are, keep the wings level 
and the aircraft pointed into the wind. Gently lower the throttle while pulling 
back on the elevator to bring the aircraft down on its wheels.
Refer to the Dual Rates and expo chart for proper fl ap to elevator mix to help 
reduce the pitching tendency from fl aps.
NOTICE: When using fl aps with this airplane, down elevator to fl ap mixing is 
required. Failure to do so may result in loss of control or a crash.
NOTICE: If a crash is imminent, reduce the throttle and 
trim fully. Failure to do so could result in extra damage 
to the airframe, as well as damage to the ESC and 
motor.
NOTICE: After any impact, always ensure the receiver 
is secure in the fuselage. If you replace the receiver, 
install the new receiver in the same orientation as the 
original receiver or damage may result.
NOTICE: Crash damage is not covered under warranty.
NOTICE: When you are fi nished fl ying, never leave the 
airplane in direct sunlight or a hot, enclosed area such 
as a car. Doing so can damage the foam.
Low Voltage Cutoff (LVC)
The ESC protects the fl ight battery from over-discharge using Low Voltage Cut-
off (LVC). Before the battery charge decreases too much, LVC removes power 
supplied to the motor. Power to the motor pulses, showing that some battery 
power is reserved for fl ight control and safe landing. Disconnect and remove 
the Li-Po battery from the aircraft after use to prevent trickle discharge. Charge 
your Li-Po battery to about half capacity before storage. During storage, make 
sure the battery charge does not fall below 3V per cell. LVC does not prevent 
the battery from over-discharge during storage.
NOTICE: Repeated fl ying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after fl ying by using a 
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the Z-Foam
™
 material in this aircraft, repairs to the foam can be 
made using virtually any adhesive (hot glue, regular CA, epoxy, etc). 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 CA accelerant on your aircraft can damage paint. DO NOT 
handle the aircraft until accelerant fully dries.
WARNING: 
Always decrease 
throttle at propeller 
strike.
