CAUTION:
Do not apply throttle until after throwing the F-27 aircraft.
Do not throw the F-27 with the motor turned on. A weak throw may
result in the propeller striking your hand, which could cause serious injury.

Flying Tips and Repairs
Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before flying, range check the radio system. Refer to the instruction manual
included with the transmitter 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.
Hand Launch
SAFE mode is recommended for
launching.
Get help to hand launch the
aircraft if possible. If you must
hand launch the aircraft alone,
hold the aircraft in your dominant
hand and the transmitter in your
other hand. Begin with the power
off, then throw the airplane. Apply
throttle after the model is in the air.
Launch the model Into the wind
with the wings level and the nose
only a few degrees above level.
Flying
For your first flights with the
recommended battery pack
(EFLB22003S30), 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 power
reduces, 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 a small amount of throttle for the entire descent.
Lower the throttle to ¼ and add a small amount of up elevator to hold the nose up
and bleed off airspeed. 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 keep the nose up until the aircraft settles
down on its skid.
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)
LVC is configured for 3S batteries out of the box. 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 LVC. LVC prevents the battery from
discharging too deeply by reducing power and pulsing the motor, which
doubles as an audio alert. Land immediately when the ESC indicates LVC is
being used to ensure there is power reserved for flight controls and a safe
landing.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent
it from being over discharged.
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 (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 the accelerant fully dries.
WARNING:
Always decrease
throttle at propeller
strike.
In Flight Trimming (BNF only)
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 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 flight performance.
3 Seconds
Post Flight
1. Disconnect the flight battery from the ESC (Required for Safety and
battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Repair or replace all damaged parts.
6. Store the flight battery apart from the aircraft and monitor the
battery charge.
7. Make note of the flight conditions and flight plan results, planning for
future flights.
