Flying Tips and Repairs

Consult local laws and ordinances before choosing a fl ying location.
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.
Takeoff
Place the aircraft in position for takeoff (facing into the wind). Select low rates
for fi rst takeoff and gradually increase the throttle to full and steer with the
nose wheel. Allow the model to accelerate to fl ying speed, then pull back gently
on the elevator and climb to a comfortable altitude.
Flying
Always choose a wide-open space for fl ying. Due to the higher speeds of this
aircraft, it does require more room to fl y than average foam models. It is ideal
for you to fl y at a sanctioned fl ying fi eld. If you are not fl ying at an approved
site, 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.
Landing
For your fi rst few fl ights with the recommended battery pack (SPMX32006S30),
set your transmitter timer or a stopwatch to 3 minutes, 30 seconds (3:30), then
land. Adjust your timer for longer or shorter fl ights once you have fl own the
model.
If at any time the motor pulses, land the aircraft immediately and recharge
the fl ight battery. See the Low Voltage Cutoff (LVC) section for more details on
maximizing battery health and run time.
Turn the aircraft into the wind, reduce the throttle and extend the landing
gear and Flaps. The fl aps will allow the aircraft to slow to a more manageable
landing speed while still maintaining lift. Elevator trim may be necessary
to maintain level fl ight with the addition of fl aps. Use the throttle during the
landing approach to control the rate of descent. Keep the wings level and the
aircraft pointed into the wind. As you approach the threshold of the runway and
approximately 1 meter altitude, decrease the throttle and begin your fl are by
easing back on the elevator. Continue back pressure on the elevator to bring
the aircraft down gently on the runway.
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.

SAFE Select Flying Tips

When fl ying in SAFE Select mode the aircraft will return to level fl ight any time
the aileron and elevator controls are at neutral. Applying aileron or elevator
control will cause the airplane to bank, climb or dive, and the amount the stick
is moved will determine the attitude the airplane fl ies. Holding full control will
push the aircraft to the pre-determined bank and roll limits but it will not go
past those angles.
When fl ying with SAFE Select it is normal to hold the control stick defl ected
with moderate aileron input when fl ying through a turn. To fl y smoothly with
SAFE Select avoid making frequent control changes and don't attempt to
correct for minor deviations. With SAFE Select, holding deliberate control inputs
will command the aircraft to fl y at a specifi c angle and the model will make all
corrections to maintain that fl ight attitude.
Return the elevator and aileron controls to neutral before switching from SAFE
Select mode to AS3X mode. If you do not neutralize controls when switching
into AS3X mode, the control inputs used for SAFE Select mode will be
excessive for AS3X mode and the aircraft will react immediately.

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 aircraft in direct
sunlight or in a hot, enclosed area such as a car. Doing so can damage the
aircraft.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge.
The ESC protects the fl ight battery from over-discharge using Low Voltage
Cutoff (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. If the motors pulse
in fl ight, land immediately and recharge the battery.
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 (XBC100 Smart Battery Checker & Servo Driver
(SPMXBC100), sold separately).
Oscillation
Once the AS3X system is active (after advancing the throttle for the fi rst time),
the control surfaces will react to aircraft movement. In some fl ight conditions
oscillation may occur (the aircraft rocks back and forth on one axis due to
overcontrol). If oscillation occurs, refer to the Troubleshooting Guide for more
information.
Repairs
Thanks to the EPO 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.
NOTICE: Use of CA accelerator on your aircraft can damage paint. DO NOT
handle the aircraft until accelerator fully dries.
Differences between SAFE Select and AS3X modes
This section is generally accurate but does not take into account fl ight speed,
battery charge status, and many other limiting factors.
• In SAFE Select mode the aircraft will self level when the control
stick is neutralized. In AS3X mode the aircraft will continue to fl y
at its present attitude when the control stick is neutralized.
• In SAFE Select mode holding a small amount of control will result in
the model banking or pitching to a moderate angle and remaining at
that angle as long as the control stick doesn't move. In AS3X mode
holding a small amount of control will result in the model continuing to
pitch or roll at a slow rate as long as the control stick doesn't move.
• In SAFE Select mode holding full control will result in the airplane
banking or pitching to the predetermined limits and the aircraft
will keep fl ying at that attitude as long as the control stick is fully
defl ected. In AS3X mode holding full control will result in the aircraft
pitching or rolling as fast as possible, and it will continue to rapidly
change attitude as long as the control stick is fully defl ected.
