Flying Tips and Repairs

Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the first time),
you will normally see the control surfaces react to aircraft movement. In some
flight conditions you may see oscillation (the aircraft rocks back and forth on one
axis due to overcontrol). If oscillation occurs, refer to the Troubleshooting Guide
for more information.
Takeoff
Place the aircraft facing into the wind. Set your transmitter in low rate and use
your flaps switch to drop the flaps to takeoff or "half position". Gradually increase
the throttle to ¾ and steer with the rudder. Flaps make takeoffs shorter. As the
tail comes off the ground, pull back gently on the elevator. When airborne, flip
your gear switch to raise your landing gear. Climb to a comfortable altitude and
then flip your flaps switch to level the flaps.
Flying
For your first flights with the recommended battery pack (SPMX50006S30), set
your transmitter timer or a stopwatch to 3 minutes. After three minutes, land the
aircraft. Adjust your timer for longer or shorter flights once you have flown the
model. If at any time the motor pulses, land the aircraft immediately to recharge
the flight battery. See the Low Voltage Cutoff (LVC) section for more details on
maximizing battery health and run time.
Landing
Land the aircraft into the wind. Use high rate Elevator for landings. Use a small
amount of throttle for the entire descent. Lower the throttle to ¼ and flip your
flaps switch to deploy the flaps to the landing or "full down position". Flaps will
make the landing approach steeper and slower, and allow for a smoother
landing. Flip your gear switch to lower your landing gear. This will slow the
aircraft further.
Keep the throttle on until the aircraft is ready to flare. During flare, 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.
If landing on grass, it is best to hold full up elevator after touchdown and when
taxiing to prevent nosing over.
SAFE

Select Flying Tips

®
When flying in SAFE Select mode the aircraft will return to level flight any time
the aileron and elevator controls are at neutral. Applying aileron or elevator
control will cause the airplane to bank, climb or dive. The amount the stick is
moved will determine the attitude the airplane flies. Holding full control will
push the aircraft to the pre-determined bank and roll limits, but it will not go
past those angles.
When flying with SAFE Select, it is normal to hold the control stick deflected
with moderate aileron input when flying through a turn. To fly smoothly with
SAFE Select, avoid making frequent control changes and don't attempt to
correct for minor deviations. Holding deliberate control inputs will command
the aircraft to fly at a specific angle, and the model will make all corrections to
maintain that flight attitude.
When flying with SAFE Select, throttle will make the aircraft climb or descend.
Full throttle will cause the aircraft to pitch up and climb slightly. Mid throttle
will keep the airplane flying level. Low throttle will cause the airplane to
descend slightly nose-down.
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.
Once on the ground, avoid sharp turns until the plane has slowed enough to
prevent scraping the wingtips.
WARNING: Always decrease throttle at propeller strike.
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 finished flying, 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 flight 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 flight 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 flying to LVC will damage the battery.
Tip: Monitor your aircraft battery's voltage before and after flying by using a Li-Po
Cell Voltage Checker (SPMXBC100, sold separately).
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. 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.
