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.
Climb to a comfortable altitude and then use your flaps switch to raise the
flaps for normal flight.
Flying
For your first flights with the recommended battery pack (SPMX22003S30),
set your transmitter timer or a stopwatch to 5 minutes. After five 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 use 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
slower landing.
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.
Once on the ground, avoid sharp turns until the plane has slowed enough to
prevent scraping the wingtips.
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 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.
During your first flight, trim the aircraft for level flight at 3/4 throttle with flaps up. Make small trim
adjustments with your transmitter’s trim switches to straighten the aircraft’s flight path.
After adjusting trim, do not touch the control sticks for 3 seconds. This allows the receiver to learn the
correct settings to optimize AS3X performance.
Failure to do so could affect flight performance.
