We recommend fl ying your aircraft outside in no 
greater than moderate winds, or indoors in a large 
gymnasium. 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.

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.

Quique’s Propeller Balancing Tip

NOTICE:

 If the propeller is not balanced, the 

aircraft may vibrate, causing the aircraft to operate 
incorrectly and/or decrease the life of the servos.

Before making any adjustments, always ensure 
the propeller has come to a complete stop and the 
throttle and throttle trim are fully lowered.

NOTICE:

 Always use eye protection while balancing 

a propeller or injury can result.

1.   Typical propeller balancers may not yield 

satisfactory results on small propellers. 
Instead, test for vibration by carefully holding 
the aircraft fuselage behind the wings while 
increasing the throttle on your transmitter.

2.   If you feel vibration, apply a small piece of clear 

tape (approximately 20mm by 6mm, depending 
on the thickness) evenly across the propeller 
blade’s leading edge.

3.   Test for vibration. Move the tape to the other 

blade or remove tape in small amounts until 
you decrease vibration to your satisfaction.

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.

IMPORTANT: 

The cellophane on the bottom of 

the wing may show wrinkles. Wrinkles vary with 
the passage of time. Wrinkles do not change the 
aircraft’s fl ight performance. 

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.
