Flying Tips and Repairs

Post Flight Checklist

1

Disconnect the fl ight battery from the ESC.

2

Power OFF the transmitter.

3

Remove the fl ight battery from the aircraft.

4

Recharge the fl ight battery.

5

Repair or replace all damaged parts.

6

Store the fl ight battery apart from the aircraft 
and monitor the battery charge.

7

Make note of the fl ight conditions and fl ight 
plan results, planning for future fl ights.

Range Check your Radio System

After fi nal assembly, range check the radio system 
with the aircraft. Refer to your specifi c transmitter 
instruction manual for range test information.

Flying

We recommend fl ying your aircraft outside in no 
greater than moderate winds. Always avoid fl ying 
near houses, trees, wires and buildings. You should 
also be careful to avoid fl ying in areas where there 
are many people, such as busy parks, schoolyards 
or soccer fi elds. Consult local laws and ordinances 
before choosing a location to fl y your aircraft.

Hand Launching

To hand launch the aircraft, hold the fuselage behind 
the wings. Advance to the throttle to 3/4 throttle  
and give the aircraft a fi rm throw, slightly up (5–10 
degrees above the horizon), and directly into the 
wind. After the model gains altitude and speed, 
decrease the throttle as you desire. 

TIP:

 The electric ducted fan (EDF) acts like a jet 

aircraft, so control is generated by airspeed rather 
than air from a propeller moving over the 
control surfaces.

Takeoff 

Taxi the aircraft in position for takeoff (facing into 
the wind if fl ying outdoors). Gradually increase the 
throttle to full power. Hold a small amount of up 
elevator and steer with the rudder. When the aircraft 
lifts off, climb gently and adjust the trim for level 
fl ight. Do not trim the aircraft while SAFE Select 
is active. Always trim the aircraft in AS3X mode. 
Once the trim is adjusted, begin exploring the fl ight 
envelope of the aircraft.

Landing

Always land into the wind. Fly the landing pattern with 
a slightly nose high attitude. Use throttle management 
to control the descent rate of the aircraft.  

During fl are, keep the wings level and the aircraft 
pointed into the wind. Slowly lower the throttle while 
easing back on the elevator to bring the aircraft 
gently down on the main wheels or to smoothly 
belly land. 

NOTICE:

 Always fully lower the throttle at touch 

down when landing the aircraft to prevent intake 
of foreign objects, which can damage the ducted 
fans and motors.

Failure to lower the throttle stick and trim to the 
lowest possible positions during a crash could result 
in damage to the ESC in the receiver unit.

Over-Current Protection (OCP)

The aircraft is equipped with over-current protection. 
OCP protects the ESC from overheating and stops 
the motor when the transmitter throttle is set too 
high and the rotor cannot turn. OCP will only activate 
when the throttle is positioned just above 1/2 
throttle. After the ESC stops the motor, fully lower the 
throttle to re-arm the ESC. 

Repairs

Crash damage is not covered under warranty. 

Repair this aircraft using foam-compatible CA glue 
or clear tape. Only use foam-compatible CA glue 
as other types of glue can damage the foam. When 
parts are not repairable, see the Replacement Parts 
List for ordering by item number.

NOTICE: 

Use of foam-compatible CA accelerant 

on your aircraft can damage paint. DO NOT 
handle the aircraft until accelerant fully dries.
