Flying Tips and Repairs
Consult local laws and ordinances before choosing a
flying 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.
Hand Launch
It is advisable to have a helper for the rst few hand launches.
Hold the airplane by the fuselage near the C.G. location. Run
the motor up to full throttle and give a moderate throw straight
ahead. The aircraft should be launched with the nose up 5–10
degrees and directly into the wind.
Flying
CAUTION: This model is equipped with a powerful
motor. Full throttle should only be used to climb to
soaring altitudes and for straight and level ight. Throttle must
be reduced during aerobatic maneuvers or during a dive to
avoid excessive stress on the airframe.
It is ideal for you to y at a sanctioned ying eld. If you are
not ying at an approved site, always avoid ying near houses,
trees, wires, and buildings. You should also be careful to avoid
ying in areas where there are many people, such as busy
parks, schoolyards, or soccer elds.
In-Flight Trimming
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
landing, adjust the linkages mechanically to account for trim
changes and then reset the trims to neutral. Ensure the aircraft
will y straight and level with no trim or sub-trim.
Landing
For your first flights with the recommended battery
pack (EFLB13503530), set your transmitter timer or a
stopwatch to 5 minutes. After 5 minutes, land the aircraft.
Adjust your timer for longer or shorter flights once you
have flown the model. When motor power becomes
noticeably reduced, 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.
Use a small amount of throttle for the initial approach. Once the
aircraft is on a proper approach angle and the aircraft will land
in the proper area, remove all throttle but maintain the descent.
During approach and landing, keep the wings level and the
aircraft pointed into the wind. As you approach 2-3 feet in
altitude, begin your are. Continue easing back on the elevator
to bring the aircraft down gently on the belly. Immediately after
landing, unplug and remove the battery. Allow the electronics to
cool before your next ight.
NOTICE: If a crash is imminent, reduce
the throttle fully. Failure to do so could
result in extra damage to the airframe,
as well as damage to the prop 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.
WARNING:
Always
decrease throttle
before prop
strike.
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 reduced, 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 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 ying to LVC will damage the battery. If
necessary, decrease the time on your ight timer so the alarm
occurs prior to reaching LVC.
Tip: Monitor your aircraft battery’s voltage before and after
ying by using a Li-Po Cell Voltage Checker (DYNF0002, sold
separately).
Repairs
Thanks to the 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 accelerant on your aircraft can damage paint.
DO NOT handle the aircraft until accelerant fully dries.
