Extra 300 PNP/BNF Instruction Manual

Congratulations on your selection of the high performance
aerobatic ParkZone® Extra 300. The original aircraft was
designed in 1987 by Walter Extra. The Extra 300 is one of the

most recognized full-scale aerobatic aircrafts in the world.
Mike McConville designed this park-sized version to give you
a scale aerobatic experience like no other. Rudder control

is pure, so no pitch or roll coupling makes knife edge flight
easier. The Extra 300 is capable of positive and negative G
maneuvers, snap rolls and other precision aerobatics. The
specially designed power system adds vertical performance
too.

Since the Extra 300 can be ready for flight in as little as an
hour, you can spend your time refining your flying skills, not
your building skills.

Low Voltage Cuto (LVC)

The Extra 300 receiver features a soft low voltage cutoff (LVC)
that occurs when the battery reaches 3V per cell under load.

When the soft cutoff occurs, the electronic speed control (ESC)
and receiver reduce power to the motor (regardless of the
power level set with the throttle stick). This prevents the voltage

of the battery from dropping below 3V per cell.

While it is possible to continue flying the aircraft after the soft

LVC occurs, this is NOT recommended. Battery discharge after
LVC will damage the Li-Po battery, resulting in less power and

shorter flight duration during subsequent flights, or complete
failure of the battery.

Discharging the battery after low voltage cutoff may result in
loss of control. Battery power may drop below the receiver’s

®

ONLY

minimum operating voltage so flight controls do not respond
to the transmitter.

Stay aware of the power level of the battery/aircraft throughout
the flight, and when the aircraft requires more throttle than
typical, immediately land the Extra 300.

Note: Battery performance is reduced in cooler temperatures. It

is recommended the batteries are warm before flight.

CAUTION: ALWAYS disconnect the battery from the

aircraft to prevent trickle discharge of the battery. These
batteries require regular maintenance to keep them at a
usable charge level.

Battery Warnings

• Never charge the battery unattended. When charging the

battery you should always remain in constant observation to
monitor the charging process and react to potential problems
that may occur.

• After flight, the battery must be cooled to ambient temperature

before charging.

• DO NOT USE A Ni-Cd OR Ni-MH CHARGER. Failure to charge

the battery with a compatible charger may cause fire resulting
in personal injury and/or property damage.

• When flight battery balloons or swells, immediately remove

the battery from service.

If at any time during the charge process the battery begins
to balloon or swell, discontinue charging or discharging
immediately. Quickly and safely disconnect the battery, then
place it in a safe area away from flammable materials to observe
it for at least 15 minutes. Continuing to charge or discharge a
battery that has begun to balloon or swell can result in a fire.

• A battery that has ballooned or swollen even a small amount

must be removed from use immediately.

• Store the battery at room temperature in a dry area for best

results.

• When transporting or temporarily storing the battery the

temperature range should be from 40–120º F. Do not store
battery or model in a car or direct sunlight.

If stored in a hot car, the battery can be damaged or even catch
fire.

• Do not over-discharge the Li-Po flight battery. Discharging

the battery too low can cause damage to the battery resulting
in reduced power, duration or failure of the battery. (See details
below).

Li-Po cells should not be discharged to below 3V each under

load.

In the case of the Li-Po battery used for the Extra 300, you will
not want to allow the battery to fall below 3V per cell during

flight.

ONLY

Charging the Flight Battery

Your Extra 300 comes with a DC balancing charger and 3S Li-Po
battery. You must charge the included Li-Po battery pack with a
Li-Po specific charger only (such as the included charger). Never

leave the battery and charger unattended during the charge
process. Failure to follow the instructions properly could result

in a fire. When charging, make certain the battery is on a heat-

resistant surface. It is recommended to charge the battery pack
while you are assembling the aircraft. The flight battery will be
required to confirm proper aircraft operation in future steps.

The Battery Charging Process

1. Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not

damaged e.g., swollen, bent, broken or punctured.

DC Li-Po Balancing Charger Features

• Charges 2- to 3-cell lithium polymer battery packs

• Variable charge rates from 300mAh to 2-amp

• Simple single push-button operation

• LED charge status indicator

• LED cell balance indicator

• Audible beeper indicates power and charge status

• 12V accessory outlet input cord

Specifications

• Input power: 12V DC, 3-amp

• Charges 2- to 3-cell Li-Po packs with minimum

capacity of 300mAh

3S 11.1V 2200mAh Li-Po Battery Pack
The ParkZone 3S Li-Po battery pack features a balancing

lead that allows you to safely charge your battery pack

when used with the included ParkZone Li-Po balancing

charger.

2. Attach the input cord of the charger to the appropriate power supply (12V accessory outlet).

3. When the Li-Po charger has been correctly powered up, there will be an approximate 3-second delay, then an
audible “beep” and the green (ready) LED will flash.

4. Turn the control on the Amps selector so the arrow points to the charging rate required for the Battery (see chart,

for example the Extra 300’s 2200mAh Li-Po battery will charge at 2.0 amps). DO NOT change the charge rate once

the battery begins charging.

5. Move the cell selector switch to 2-cell or 3-cell for your battery.

6. Connect the Balancing Lead of the Battery to the 2-cell (it has three (3) pins) or 3-cell (it has four (4) pins) Charger

port.

7. The green and red LEDs may flash during the charging process, when the charger is balancing cells. Balancing

prolongs the life of the battery.

8. When the battery is fully charged, there will be an audible beep for about 3 seconds, and the green LED will shine

continuously.

9. Always unplug the battery from the charger immediately upon completion of charging.

CAUTION: Overcharging a battery can cause a fire.

Transmitter and Receiver Binding

Binding is connecting a transmitter to an aircraft receiver wirelessly or electronically so the aircraft receiver recognizes the transmit­ter GUID (Globally Unique Identifier) code. Binding is necessary for proper operation.

The Extra 300 requires a DSM2 full range (high power) transmitter. The list below is Spektrum™ or JR® DSM2-equipped full range

transmitters and modules that can bind to the Extra 300’s receiver:

•Spektrum DX5e •Spektrum DX6i •Spektrum DX7/DX7se •JR X9303/9503 2.4 •JR 11X •JR 12X 2.4 •All SPM Module systems

Note: When using a Futaba transmitter with an aircraft receiver, reversing the throttle channel may be required.

CAUTION: ALWAYS power on the transmitter before connecting the ight battery to the aircraft ESC. ALWAYS

disconnect the ight battery from the aircraft ESC before powering o the transmitter.

Additional Binding Information

Before each flight, power on the transmitter and wait about five (5) seconds
before connecting the flight battery to the aircraft ESC. The transmitter scans
and secures two radio frequencies for aircraft control. When the flight battery
is connected too quickly for the transmitter to make frequency selection, the
transmitter and receiver may not connect. When there is no connection, leave the transmitter powered on, disconnect the flight
battery then connect the flight battery to the receiver.



1. Read transmitter instructions for binding to a receiver (location of transmitter’s Bind control).

2. Make sure transmitter is powered o.

3. Install a bind plug in the receiver Batt/Bind port.

4. Connect the flight battery to the ESC. The receiver LED will begin to flash rapidly.

5. Move the transmitter controls to neutral (flight controls: rudder, elevators and ailerons) or to low

positions (throttle, throttle trim, and flight control trims).*

6. Power on the transmitter while holding the transmitter bind button or switch. Refer to your

transmitter’s manual for binding button or switch instructions.

7. The receiver light will go from ashing rapidly to ashing slowly. After 5–10 seconds the light will

become solid indicating the receiver is bound to the transmitter.

8. Remove the bind plug from the receiver.

9. Safely store the bind plug (some owners attach the bind plug to their transmitter using two-part loops

and clips).

10. The receiver should keep the binding to the transmitter until a bind plug is put in the receiver Batt/

Bind port.

* The throttle will not arm if the transmitter’s throttle control is not put at the lowest position.

If problems are encountered, obey binding instructions and refer to transmitter troubleshooting guide
for other instructions. If needed, contact the appropriate Horizon Product Support office.

Installing Wings

1. Put the wing tube in the round hole in the wing slot of the
fuselage.

2. Put left wing on the wing tube.

6. Attach the two (2) aileron connectors to the aileron Y-harness

in the fuselage.

3. Move the wing on the tube into the slot in the fuselage while
putting the aileron control connector in the fuselage.

4. Fully install left wing in fuselage using screw.

Note: There is no difference between the two connections on
the Y-harness. Left and right servo lead connectors do not have
to be connected to a particular side of the Y-harness.

Tip: Install aileron servo wires in the fuselage’s molded

channels using tape. Tape will keep the wires from blocking
battery installation.

5. Install the right wing using the steps above.

Note: Due to the Z-foam™ construction of the Extra 300, the

wing can flex to absorb flight loads during hard positive
or negative G forces. This is more noticeable during hard
maneuvering, but is normal.

8

Installing Horizontal Tail and Pushrods
on Control Horns

Installing the Horizontal Tail

1. Put the horizontal tail (PKZ5125) in the fuselage, making
sure the control horn is on the right side of the fuselage. The
control horn is the part on the elevator where the pushrod and
clevis attach.

Note: Alignment marks are on the top and bottom of the

horizontal tail.

2. Make sure the center of the horizontal tail is aligned with the
center of the fuselage.

3. Install clear tape on the top and bottom of the horizontal tail
and the fuselage.

Installing Pushrods on Control Horns

CAUTION: The installation positions of the pushrods

and clevises directly aect aircraft response. When these

are incorrectly connected for the pilot’s skill level,
unexpected aircraft response to controls can result in
unintended crash damage to the aircraft.

1. Pull the elastic band from the clevis up to the pushrod.

2. Carefully spread the clevis and put the clevis pin to the
outermost hole in the control horn.

Tip: The clevis can be threaded in and out to shorten or lengthen

the pushrod. Make sure transmitter trims are centered before
making mechanical adjustments.

Tip: Removal of tape from painted parts can remove paint.

Battery Selection and Installation

We recommend the ParkZone 2200mAh 11.1V 25C •
Li-Po battery (PKZ1029).

If using another battery, the battery must be at least a •
25C 2200mAh battery.

Your battery should be approximately the same •
capacity, dimensions and weight as the ParkZone

Li-Po battery to fit in the fuselage without changing

the center of gravity a large amount.

Range Check and Pre-Flying Tips

Range Check your Radio System

After final assembly, range check the radio system with the Extra

300. Refer to your specific transmitter instruction manual for

range test information.

Before Each Flying Session

• Always make sure your Extra 300 is properly trimmed prior to

each flight

• Always make sure the receiver, ESC, and battery are secured

in the fuselage.

• Turn on the transmitter before plugging in the flight battery.

With the aircraft on the ground and motor running, you should
walk away approximately 100 feet and still have full control of
all functions while following the specific range test feature of
your DSM2 transmitter. If this is not the case, do not fly. Contact
the appropriate Horizon Product Support office. See page 20.

• Always make sure that all controls are functioning per the

transmitter input you are giving. This includes ailerons, rudder,
elevator and throttle.

• Always make sure you have fully charged the transmitter

batteries or make sure your transmitter has fresh batteries
before you fly.

• Always make sure the servo reversing switches on the

transmitter are set correctly.

• Always make sure the dual rates switch is at the rate setting
where you plan to fly. We recommend LOW rates for your initial
flying. The Extra 300 is VERY maneuverable on high rates and

requires a lot of experience to handle properly.

CAUTION: Always remove the ight battery from the

aircraft when you are done ying, or when you are on the

way to the ying eld.

Flying Tips and Repairs

Flying

Always choose a wide-open space for flying your ParkZone Extra
300 BNF. It is ideal for you to fly at a sanctioned flying field. If

you are not flying at an approved site, always avoid flying near
houses, trees, wires and buildings. You should also be careful
to avoid flying in areas where there are many people, such as
busy parks, schoolyards, or soccer fields. Always follow local
ordinances. We recommend only flying your Extra 300 in light
winds.

Note: The Parkzone Extra 3oo is a high performance aircraft. Full

power should only be used for vertical climbs. Avoid high power
settings in dives or tight turns.

Takeoff

Choose a large open area with a smooth surface for takeoff.

Face the nose of the aircraft into the wind. Slowly apply ∏ - ≤

throttle and let the aircraft get up to flying speed while steering
with the rudder and tailwheel. Hold up the elevator at the
start of the takeoff roll to keep the tailwheel in contact with
the ground until enough airspeed has been reached that the
rudder becomes effective. The tailwheel will lift off the ground.
Move the elevator to neutral while speed increases to prevent
the aircraft from becoming airborne too quickly. Gently apply
a small amount of up elevator and let the aircraft climb to a
desired altitude.

Landing

Start the landing approach by reducing throttle to 1/4 or less to

slow the aircraft. Fly the aircraft down to about 1-2 feet above

the runway. Slowly reduce power until the throttle is in the off
position. Apply up elevator as the aircraft settles to the runway.

The Extra can do a main landing gear landing, or two-point

landing, where the aircraft touches down on the main wheels
first and the tailwheel is off the ground. The Extra 300 can also

land in three-point attitude when all three wheels touch the

runway at the same time.

Repairs

Thanks to the Extra 300’s Z-foam™ construction, repairs to

the foam can be made using virtually any adhesive (hot glue,
regular CA, epoxy, etc). When parts are not repairable, see the

Replacement Parts List for ordering by item number.

Note: Due to the Z-foam™ construction of the Extra 300, the

wing can flex to absorb flight loads during hard positive
or negative G forces. This is more noticeable during hard
maneuvering, but is normal.
