INTRODUCTION
QQ Extra 300 and Aura 8: the perfect combination!
The QQ Extra 300 - it is the evolution and accumulation of many years of
experience in the aerodynamic and electronic control stabilization world.
A perfectly balanced airframe design combined with today’s most
advanced control system gives an unmatched ying experience.
Pilots will feel smooth, precise aircraft control without any interference to
pilot inputs. The aircraft will y as if it were much larger, turbulent air will
be less noticeable, rotations will stop more precisely and landing will be
easier to execute. Flex Innovations has tuned and matched both to their
best potential, however, the Aura 8 programming capability allows total
freedom to the pilot to adjust (including setting ight modes that can
switch it o). USB rmware update capability allows you to enjoy and
benet from the latest features and advancements.
§ Available in blue/yellow and red/silver schemes

BATTERY CHARGING GUIDELINES
The assembly of the QQ Extra 300 can be accomplished in
less than twenty minutes, even for a novice. Prior to
assembling the airplane, it is advisable to charge your
battery so that you are ready to y upon completion of the
assembly of your model.
We recommend the use of an advanced LiPo balancing
charger, such as our Potenza C80 Multi Chemistry Touch
Screen AC/DC balancing charger for your batteries to get
the maximum performance and lifespan from them.
Our airplanes are designed around our Potenza LiPo
batteries and we recommend the Potenza 3S 2200mAh 40C
LiPo in the QQ Extra 300 based on our extensive testing and
development. This battery features an EC3 connector, so no
soldering is required for use in your Extra.
Both are available at your Flex Innovations retailer.

SAFETY WARNINGS AND PRECAUTIONS
Protect yourself and others by following these basic safety guidelines.
1. This manual contains instructions for safety, operation and maintenance. It is essential to read and follow all the instructions and warnings
in the manual, prior to assembly, setup or use, in order to operate correctly and avoid damage or serious injury.
2. This model is not a toy, rather it is a sophisticated hobby product and must be operated with caution and common sense. This product
requires some basic mechanical ability. Failure to operate this product in a safe and responsible manner could result in injury or damage
to the product or other property.
3. This model must be assembled according to these instructions. Do not alter or modify the model outside of these instructions provided by
Flex Innovations, Inc, as doing so may render it unsafe and/or unyable. It is your responsibility to ensure the airworthiness of the model.
4. Inspect and check operation of the model and all its components before every ight.
5. If you are not an experienced pilot or have not own a high-performance model before, it is recommended that you seek assistance from
an experienced pilot in your R/C club for your rst ights. If you’re not a member of a club, the Academy of Model Aeronautics (AMA) has
information about clubs in your area whose membership includes experienced pilots.
6. Keep the propeller area clear from such items such as loose clothing, jewelry, long hair, or tools as they can become entangled. Keep your
hands and body parts away from the propeller as injury can occur.
7. Never y in visible moisture or submerge the airplane or any of its electronic components in water. Permanent damage to electronic
components may occur, or corrosion of components may lead to intermittent failures.
LOW VOLTAGE CUTOFF
LiPo batteries have a nominal (rated) voltage of 3.7v per cell, and fully charged, reach 4.2v per cell. Batteries are designed to be discharged
below the nominal voltage, however, if they are discharged below 3.0v per cell, damage will occur and the pack will lose capacity. For best
long term battery life, set a timer and land after a time that leaves approximately 15% of the battery’s capacity remaining.
Low voltage cuto is a feature that is built into the Hobby Wing SkyWalker 40A ESC that is designed to protect the connected battery from
being discharged too far and causing permanent damage to the cells. Circuitry within the ESC will automatically detect when the input
voltage from the battery pack reaches below 3.15v per cell (average) and will remove power to the motor, but still deliver power to the
servos so that a safe landing may be made. If the motor begins to lose power rapidly during ight, the LVC has sensed that the total voltage
of the pack has dropped below 3.15v per cell average, and the airplane should be landed immediately.

MAIN LANDING GEAR INSTALLATION
Required Tools and Fasteners: #1 Phillips Screwdriver, (4) M1.5x5 self-tapping screws
1. Insert the landing gear assembly into the slot in the bottom of the fuselage. The gear will sweep forward.
2. Install the cover plate over the landing gear slot and attach with (4) M1.5x5mm self-tapping screws.
TAILWHEEL INSTALLATION
Required Tools and Fasteners: #1 Phillips Screwdriver, (3) M1.5x5 self-tapping screws
1. Insert the tailwheel assembly in the slot in the bottom of the rudder.
2. Install the cover plate over the tailwheel slot and attach with (3) M1.5x5mm self-tapping screws.
5
HORIZONTAL STABILIZER INSTALLATION
Required Tools and Fasteners: Clear Tape (4 strips)
1. Insert the horizontal stabilizer tube into the fuselage and roughly center.
2. Slide the left and right stabilizer halves onto the tube. Ensure that the control horn orients towards the belly of the airplane and that the
elevator joiner tabs are properly indexed. Do not force the stabilizer into place.
3. Apply 4 pieces of clear tape to the joint between the stabilizer and the plastic mounts. Be sure to apply tape to both the top and bottom.
4. Attach the clevis to the elevator control horn in the innermost hole. Slide the clear tubing over the forks.
