Post Flight Checklist

1.

  Disconnect the fl ight battery from the ESC 

(Required for safety and battery life).

2. 

 Power OFF the transmitter.

3.

  Remove the fl ight battery from the 

aircraft.

4.

  Recharge the fl ight battery.

5.

  Store the fl ight battery apart from the 

aircraft and monitor the battery charge.

6.

  Make note of the fl ight conditions and 

fl ight plan results, planning for future 
fl ights.

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

Always 

decrease throttle at

propeller strike.
