EFL5150 Clipped Wing Cub Manual
EN
During your rst ight, trim the aircraft for level ight at 3/4 throttle. Make
small trim adjustments with your transmitter’s trim switches to straighten the
aircraft’s ight path.
After adjusting the 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 ight performance.
Flying Tips and Repairs
In Flight Trimming
3 Seconds
Consult local laws and ordinances before choosing a ying location.
Range Check your Radio System
Before you y, range check the radio system. Refer to your specic transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the rst time),
you will normally see the control surfaces react to aircraft movement. In some
ight 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. Increase
the throttle to 1/2–3/4 and steer with rudder. As the tail comes off the ground,
pull back gently on the elevator. Use the elevator as necessary to maintain the
desired climb angle.
Flying
For your rst ights with the recommended battery pack, set your transmitter
timer or a stopwatch to 5 minutes. After ve minutes, land the aircraft. Adjust
your timer for longer or shorter ights once you have own the model. If at
any time the motor power reduces, land the aircraft immediately to recharge
the ight 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.
During landing, keep the wings level and the aircraft pointed into the wind.
When landing on grass or rough surfaces, hold full up elevator after touchdown
and during taxiing to prevent nosing over. Do not taxi too quickly as the aircraft
can become airborne again at a very low airspeed.
Once on the ground, avoid sharp turns until the plane has slowed enough to
prevent tipping and scraping the wingtips.
NOTICE: If a crash is imminent, reduce the throttle and
trim fully. Failure to do so could result in extra dam-
age 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 nished 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 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 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 stor-
age. 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 ying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after 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.
