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.

CAUTION
Always connect the battery when the throttle and
throttle trim are in the cut-o position.
Observe the following procedures to safely power up your
model after it has been bound. Ensure propeller is removed
unless sequence is followed to power up before ight.
1. Lower the throttle stick and trim to their lowest setting
and turn on the transmitter. Wait for your transmitter to
indicate the RF signal is being broadcast before proceeding.
If a battery is connected to the ESC with the throttle fully
open on the active transmitter, the ESC will enter into
programming mode. If this occurs, simply disconnect the
battery, lower the throttle, and reconnect the battery.
2. Ensure the rudder, elevator, and aileron gimbals are
centered.
3. With the airplane on a solid surface; connect the battery
tothe ESC and wait. The ESC will emit a series of audible
tones during its initialization process.
4. The ESC will emit a short, nal tone sequence indicating
that the ESC is now armed.

Description of Pre-Loaded Aura Flight Modes
Mode 1: Flight Control system is o. Rates are set for general
ight (same as FM 2). Exponential is tuned for comfortable ight.
Mode 2: Flight Control system is on. Gains are moderate and
tuned for comfortable feel/best performance for precision
aerobatics. Expo is tuned for comfortable ight.
Mode 3: Flight Control system is on. Gains are highest and tuned
for 3D aerobatics. Rate are set to highest. Exponential is tuned for
comfortable ight.
Each of the modes has been tuned by our team to oer a solid
start. Because tastes in control feel are unique, if changes in rate
and expo are needed adjustments may be made through either
the transmitter or Aura 8. Changes on gain value may only be
made through the Aura.

PROPELLER/SPINNER INSTALLATION
Required Tools and Fasteners: #1 Phillips Screwdriver, 13mm Box Wrench, M3x6mm machine screw
1. Insert the prop collet onto the motor shaft. Ensure that it is fully seated.
2. Temporarily remove the prop nut and washer and install the propeller with the convex surface facing forward. The propeller size numbers
are printed on the front face of the prop and should orient forward.
3. Slide the prop washer on the collet with the widest face aft, and tighten the prop nut.
NOTICE
Because the spinner does not have a backplate, spin the motor over by hand to ensure that the spinner is true after installation.
SFG INSTALLATION
1. Liberally apply medium CA (cyanoacrylate adhesive) to the airfoil-shaped mounting plate on the inside of the SFG.
2. Insert the SFG into the molded cavity in the wingtip and press tightly. NOTE- the plastic skid is on the BOTTOM of the SFG.

CENTER OF GRAVITY
The location of the center of gravity for the QQ Extra
300 is aligned with the FRONT EDGE of the RADIO
HATCH. This measurement was determined from
many test ights by designer and many time world
aerobatic champion, Quique Somenzini. Lift the
airplane from the underside of the wing to check the
CG.
Setting the center of gravity is one of the most
important steps for success, particulary with a new
airplane. The Extra is a high-performance airplane
with large control surface throws, and a high thrust to
weight ratio. These two factors combined make it a
very enjoyable aircraft to y, but if the center of
gravity is not within an acceptable range, it will make
the airplane dicult, if not impossible, to control.
NOTICE
The CG measurement should be made with
the completed airframe with all components
(
batteries, servos, receiver, linkages, screws,
bolts, hardware, etc.) installed. Failure to do
so will result in inaccurate measurement.
BATTERY INSTALLATION
1. Push the spring-loaded battery latch tab back to release the battery hatch.
2. OPTIONAL- Apply a strip of adhesive-backed hook-and-loop fastener (not included) to the bottom of your battery and battery tray.
3. Press the battery to the center of the battery tray and secure with the provided hook-and-loop strap.
4. Reinstall the hatch, and conrm that the latch has positively engaged.
CAUTION
Always keep limbs clear from the propeller when the
battery is connected. After the ESC arms, the propeller
will rotate when the throttle is moved. Unlike an internal
combustion engine, electric motors apply more voltage
to counteract resistance, therefore any object that is
entangled in the propeller will be severely damaged
before the motor will stop
WARNING
When making adjustments to linkages, transmitter
settings, or the Aura 8 ight control system, remove
the propeller to guard against accidental spool up.

The QQ Extra 300 was designed from the ground up to be a
superior 3D aircraft. Pilot workload has been greatly reduced
thanks to its nely tuned aerodynamic design to the incredible
performance and pre-set conguration of the Aura 8 advanced
ight control system, intermediate pilots will nd that they are
now able to do what they previously only dreamed of.
Sharpening Your Skills
Obviously before attempting any of these maneuvers, you should
be procient at ying an airplane. Practice orientation maneuversbe able to y the airplane anywhere you want upright, inverted,
knife edge, ying towards yourself, ying away from yourself. Part
of learning 3D is being able to bail out of a maneuver gone wrong
consistently and safely.
A good 3D pilot will be smooth, but assertive in manipulations of
all ight controls. Throttle and rudder are just as important to
ying 3D as aileron and elevator. Competency with these controls
is a must before progressing into 3D maneuver training.
After becoming procient in basic aerobatics and being able to
comfortable control the airplane in any ight attitude, you may
progress on to some 3D maneuvers. At right, there is a list of some
of the more common 3D maneuvers in practice today. These
maneuvers are in order of increasing diculty, so be sure to work
into them in a logical progression. Once you master some of the
more basic maneuvers, try your hand at more complex maneuvers
and then practice variations of maneuvers and putting them into
a sequence. There is no limit to the QQ Extra 300’s performance
envelope.
LEARNING TO FLY 3D WITH THE QQ EXTRA 300
Harrier- The harrier is one of the most basic 3D maneuveres and is
a good maneuver to start your training. A harrier is own at a
nose-high attitude (around 45°) while maintaining constant
altitude and can be own upright or inverted. Transition into a
hover or into forward ight for recovery.
Hover- In a hover, the airplane is in a vertical attitude and is held
in place by manipulating the throttle and ight controls to
prevent the airplane from climbing or descending, and remain
stationary. Transition into a harrier or exit into a vertical upline to
recover.
Torque Roll- A torque roll is a slight modication to the hover.
Instead of keeping the airplane in a stationary hover, the the
aileron is neutralized to allow the torque of the motor to rotate
the airplane.
Waterfall- Waterfalls are accomplished by pivoting 360° in pitch
with little or no altitude change or forward movement. Transition
into a harrier or exit into a vertical upline to recover.
Blender- The blender is not a particularly dicult maneuver, but it
is very dynamic and very impressive. From high altitude, the
airplane enters a vertical downline at low throttle and rolls to the
left. At a predetermined altitude (not too low!) an outside snap is
intiated while simultaneously advancing the throttle to enter a at
spin. Ensure adequate altitude for recovery.
Harrier Roll- Harrier rolls are by far the most dicult 3D maneuver
to perfect, but without a doubt are the most impressive to the idle
bystander and R/C pilot alike. A harrier roll is as it sounds- a
continous aileron roll while performing a harrier. Many hours of
practice are required to master this maneuver, and there are many
variations to it as well.
Selecting a Flying Site
Selecting a ying site is critical to a successful ight. Airplanes
require a lot more room than other R/C products, therefore, a
neighborhood or parking lot is less than ideal. A large open eld
with short grass and generous overy area are the best candidates
if no AMA eld is available in your area. Know your overy areaensure that there are no houses, playgrounds, or other buildings
that may be damaged if the airplane were to crash.
Takeo
Taxi or place the aircraft on the runway centerline, with the nose
into the wind. Select Mode 2, then smoothly advance the throttle
to full while maintaining directional control with the rudder and
slight back pressure on the elevator. The airplane should lift o
smoothly before the throttle is fully open. Fly in Mode 2 until the
aircraft is fully trimmed (see special trimming instructions), and
you are comfortable with it's handling, then explore the other
modes as desired.
Flying
Altitude is your friend on the rst ight. Briskly climb to a safe
altitude and trim the airplane out. The airplane should y straight
and level a 1/2 to 3/4 power with no hands on the transmitter. Try
some basic maneuvers, and slowly progress into the airplane’s
ight envelope as you become more comfortable with the
airplane’s ight qualities and perfect your setup. Note: If at any
time, such as after gain adjustments, you experience
unexpected control system inputs or oscillations, switch to
Mode 1, and land and troubleshoot the issue. (Mode 1 turns

USE CAUTION WHEN FLYING YOUR QQ EXTRA IN MODE 3
AT HIGH AIRSPEEDS. DOING SO CAN INDUCE CONTROL
SURFACE OSCILLATIONS AND MAY CAUSE A CRASH.
Trimming
The rst several ights on your QQ Extra should be dedicated
to trimming and setup. Fly the airplane at full power in Mode
2 and trim for level ight. Land, adjust linkages and return
the trim and/or subtrim to zero and y again. Repeat
until the airplane ies hands o, straight and level.
Landing
Be mindful of your ight time and allow adequate battery reserve
for a couple of go-arounds, if necessary, on the rst few ights.
Select Mode 2 and slow the airplane and align with the runway,
into the wind. The airplane should descend smoothly in this
conguration with proper airspeed. Once you are close to the
ground, gradually close the throttle fully and begin to smoothly
apply up elevator as required to arrest descent and the airplane
should gently touch down with a short roll out.

AIRFRAME REPAIRS
The QQ Extra 300 is molded from durable EPO foam and is repairable with most adhesives. Similar to building and repairing wood or
composite airplanes, the correct glue for a given application is critical to the repair holding and not breaking again. For major repairs, such
as a broken fuselage, epoxy is preferred because it allows time to correct any misalignment. For smaller repairs, such as a cracked control
surface or small chunk of material missing from the airframe, regular CA is very eective. The use of odorless (foam safe) CA is not recommended on EPO foam aircraft because it is weaker than regular CA and takes a longer period of time to cure and the bond tends to be
weaker.
If a part is damaged too badly to be repaired, please refer to the front of the manual for a complete listing of spare airframe parts.
NOTE: Avoid the use of CA accelerant in repairs. It can damage paint and will weaken the bond of the glue. If CA accelerant is
used, be mindful of the locations of CA to prevent premature bonding of parts, or bonding a hand or clamp to the airframe.
REPLACING SERVOS
Required Tools and Fasteners: #1 Phillips Screwdriver
1. Unplug the servo from the receiver.
2. Unscrew the servo arm from the servo and remove the servo arm.
3. Unscrew the two mounting screws located at each end of the servo and remove.
NOTICE: If a crash is imminent, fully reduce the throttle to prevent further damage to the power system and reduce energy
to lessen impact damage. Never allow the propeller to contact the ground under power, even idle.
BE ADVISED THAT CRASH DAMAGE IS NOT COVERED UNDER ANY PRODUCT WARRANTY.
Avoid keeping the airplane in direct sunlight when not ying. Excessive heat can damage the airplane’s structure and UV
damage can permanently discolor decals.
TIP: Plug a spare extension lead into the servo when removing to make it easier to install the lead of the
servo when replaced.

SERVICING THE POWER SYSTEM
Required Tools and Fasteners: #1 Phillips Screwdriver, 13mm box wrench
1. Remove the propeller and spinner assembly from the motor.
2. Remove the cowling by unscrewing the (2) M1.5x4mm self-tapping screws from the plastic mounts on the side of the cowling.
3. Gently pry the rear of the plastic mount upward to remove it from its base and then free the cowling from the fuselage.
4. Remove the (4) bolts holding the motor to the rewall using a #1 Phillips screwdriver. Disconnect the motor from the ESC.
5. To remove the ESC, simply unplug its lead from the receiver and the output leads from the motor.
OPTIONAL WHEEL PANT REMOVAL
For yers that want the lightest possible setup, or that y o of rough/unimproved elds, the wheelpants on the Extra are designed to
be removable. Two wheel collars have been provided in the hardware bag to retain the wheels after the wheelpants are removed.
Required Tools and Fasteners: #1 Phillips Screwdriver, 1.5mm hex driver, (2) wheel collars
1. Invert the airplane and locate the two wheelpant retaining screws and remove them. Slide the wheelpants and tires o of the axles.
2. Remove the wheel from the wheelpant and reinstall on the axle.
3. Slide the wheel collar onto the axle with the shoulder (oset) side towards the wheel. Tighten the set screw on the wheel collar.
TIP: reinstall the wheelpant retaining collar and screws to prevent losing parts in case you wish to reinstall them.
TIP: use blue threadlocker on the wheel collar set screw for added security.
