We recommend fl ying your aircraft outside in calm 
conditions. 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.

Takeoff

Place the aircraft in position for takeoff (facing into 
the wind if fl ying outdoors). Set dual rates to low 
position and gradually increase the throttle to ¾ to 
full and steer with the rudder. Pull back gently on 
the elevator and climb to check trim. Once the trim 
is adjusted, begin exploring the fl ight envelope of 
the aircraft.

Landing

Land into the wind. This is very important for this 
model. Fly the aircraft to approximately 6 inches 
(15cm) or less above the runway, using a small 
amount of throttle for the entire descent. Keep the 
throttle on until the aircraft is ready to fl are. During 
fl are, keep the wings level and the airplane pointed 
into the wind. Gently lower the throttle while pulling 
back on the elevator to bring the aircraft down on 
all three wheels.

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, which may require 
replacement.

This aircraft is equipped with 
Over Current Protection (OCP). 
This feature protects the ESC 
from overheating. OCP stops the motor when the 
transmitter throttle is set too high and the propeller 
cannot turn. The OCP will only activate when the 
throttle stick is positioned just above 1/2 throttle. 
After the ESC stops the motor, fully lower the 
throttle to re-arm the ESC. 

NOTICE: 

Crash damage is not covered under the 

warranty.

Repairs

Repair the aircraft using foam-compatible CA 
(cyanoacrylate adhesive) or clear tape. 

Only use 

foam-compatible CA

, as other types of glue can 

damage the foam. 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 foam-compatible CA accelerant on 

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

NOTICE:

 When you are fi nished fl ying, never leave 

the aircraft in direct sunlight or in a hot, enclosed 
area such as a car. Doing so can damage the foam.

Flying Tips and Repairs

When a Li-Po battery is discharged below 3V per 
cell, it will not hold a charge. The aircraft’s ESC 
protects the fl ight battery from over-discharge 
using Low Voltage Cutoff (LVC). Once the battery 
discharges to 3V per cell, the LVC will reduce the 
power to the motor in order to leave adequate 
power to the receiver and servos to land the 
airplane.

When the motor power pulses, land the aircraft 
immediately and replace or recharge the fl ight 
battery. 

Always disconnect and remove the Li-Po battery 
from the aircraft after each fl ight. Charge your Li-Po 
battery to about half capacity before storage. Make 
sure the battery charge does not fall below 3V per 
cell. Failure to unplug a connected battery will result 
in trickle discharge.

For your fi rst fl ights, set your transmitter timer or a 
stopwatch to 4 minutes. Adjust your timer for longer 
or shorter fl ights once you have fl own the model. 

NOTICE: 

Repeated fl ying to LVC will damage the 

battery. 

Low Voltage Cutoff (LVC)

NOTICE: 

Always 

decrease throttle 
at propeller strike.
