J-3 Cub BL PNP Instruction Manual

Congratulations on your purchase of the ParkZone®
J-3 Cub BL PNP®. You will need to attach the wing and
landing gear. To complete the airplane assembly in addi­tion to supplying your own radio system and battery.

We at ParkZone are committed to giving you the most
enjoyable flight experience possible. In order
to have a safe and successful flight, we ask that
you do not fly until you have read these instructions
thoroughly.

Your J-3 Cub BL PNP already has the 3-wire servos,
a ParkZone 370 outrunner brushless motor, and an
E-flite®Pro 10A brushless ESC installed. The decals have
been applied as well. You will only need to add your own
battery (a 2S 800mAh Li-Po is recommended), as well as a
receiver and transmitter.

In as little as an hour, you can be ready for your first flight
with the J-3 Cub BL PNP. This means you can spend your
time refining your flying skills, not your building skills.

Warning

Although your ParkZone J-3 Cub BL PNP comes almost
ready to fly, this aircraft is for experienced RC pilots only
and is not a toy! Misuse of the plane can cause serious
bodily harm and damage to propert y. Therefore, only an
experienced RC pilot should fly it.

Step 1

Step 2

Charging Your Flight Battery

We recommend that you choose the 800mAh 2S Li-Po
(PKZ1032) to power your J-3 Cub BL PNP. The Li-Po battery
must be charged with a charger that is specifically designed
to handle Li-Po batteries, such as the ParkZone 2- to 3-cell
Li-Po Charger (PKZ1040). Regardless of the battery you
choose, always follow the charger and battery instructions
to avoid any damage to the battery, charger, property or
yourself.

Installation of Landing Gear

1. Locate the landing gear and the included
screws from within the packaging.

2. Using a Phillips screwdriver, attach the
landing gear to the fuselage as shown.

Step 3

Attaching the Wing

1. Locate wing, wing struts and rubberbands.

2. Locate wing strut screws.

3. Place wing on top of fuselage so that it is
centered.

4. Attach wing struts with the mounting screws
as shown. There should be the same amount of
slack in each strut once this is completed.

5. Once you are satisfied the wing is properly
centered and the struts are properly attached,
complete the attachment of the wing with
the included rubber bands. Stretch two of
the rubber bands from the front to the rear
attach points. Stretch the next two diagonally
across the middle. Confirm the wing is securely
attached.

6. Make sure that prior to each flight the wing
is properly centered onto the fuselage. If the
wing is not centered properly, it is impossible
to have correct flight.

Installing the Receiver

You should place your receiver in the compartment
that is directly aft of the battery holder box. This
is right at the point of CG. Carefully plug the servo
leads into the corresponding channels of the receiver
you have chosen. The servo plugs may have to be
trimmed carefully with a hobby knife (if you are using
a Spektrum™, JR® or HiTec radio system) in order to fit
correctly into the receiver.

Confirm that the servo leads/plugs are in the correct
channel of the receiver. Do this by:

1. Turning on the transmitter , confirming that the

throttle is in the "off " position.

2. Installing a charged flight batter y.

3. Plug flight battery into ESC.

Warning

Failure to use the proper charger for a Li-Po battery can
result in serious damage, and if left charging long enough,
will cause a fire. ALWAYS use caution when charging Li-Po
batteries. Never leave a battery charger unattended while
charging.

* Spektrum is used with permission of Bachmann Industries, Inc. Spektrum
radios and accessories are exclusively available from Horizon Hobby, Inc.

Check all functions to ensure proper setup. Keep all
body parts away from the propeller. You can also
make any trim adjustments to the control sur faces at
this time. Once you are satisfied that the channels
are functioning correctly, you can unplug the flight
battery and turn off the radio system.

Step 5

Step 6

Motor Test

1. Make sure the throttle is in the “off” position.

2. Turn on the transmitter.

3. Remove the battery door from bottom of the
fuselage. (See image B in Step 2 on page 2.)

4. Plug the flight battery into the red lead inside
the fuselage.

5. Secure the battery inside the fuselage cavity
and replace the battery door.

6. Your J-3 Cub BL PNP® has a built-in throttle­arming feature which needs to “see” the throttle
in the Off position before it will spin the
propeller. (CAUTION: Make sure that you, as well
as loose clothing and hair, are away from propel­ler at all times!) Advance the throttle forward
and the propeller should spin at a high speed.
The throttle-arming feature will need to be
activated each time the battery is plugged into
the airplane.

7. When finished with the motor test, continue to
Tail Control Test on the next page.

Note: It is impor tant to always turn on the transmit­ter prior to plugging in the flight battery. Plugging in
the flight battery first may cause undesired operation
due to interference, potentially resulting in damage
to the aircraft or personal injur y.

Adult Superv ision Required

WARNING: Keep everything clear of the propeller
and hold the plane securely. A moving propeller can
cause severe injury.

Choose a Large, Open Flying Site

• A large, open grassy field is required to fly your
J-3 Cub BL PNP. The J-3 Cub BL PNP flies about
15–20 mph, so it covers ground fast. The bigger
the field, the better.

• It is essential to have a minimum of 300 feet of
clear space in all directions from the pilot.
Ignoring this direction, could result in a
fly-away plane.

• Make certain that you do not fly near trees,
buildings, or other areas that can restrict your
view or interfere with your flying.

• Always keep the plane upwind from you to
avoid flyaways. This is essential!

Fly in this area

(upwind of pilot).

Step 7

Range Test
You will need two people to perform the range
test: one to hold the plane and the other to give the
transmitter input.

Warning: The person holding the plane should hold it
in a way so the propeller does not come into contact
with anything loose on their clothing or body.

1. One person holds the transmitter, while the
other person walks 100 paces away with the
airplane.

2. Be sure the throttle is in the “Off” position.

3. Extend the transmitter antenna completely and
turn the transmitter on.

4. Plug the airplane battery into the fuselage.

5. As soon as the throttle slider is advanced, the
propeller should spin quickly.

6. As the first person moves the transmitter
controls at the same time, the other person
watches to be sure the airplane’s motor and tail
controls operate smoothly.

Step 8

Seek Assistance from an Experienced
Radio Control Pilot

VERY IMPORTANT
The 3-channel control system is designed for
the experienced radio control pilot and is not intended
for the first-time flier. It is best to have HobbyZone®
Zone 2 experience. First-time pilots of the ParkZone®
J-3 Cub BL PNP should seek the assistance of an
experienced RC flier until the additional third channel,
pitch control, has been competently mastered. Crash
damage is not covered under the warranty.

Warnings and Safety

1. Read and follow this manual completely, observing
all instructions and safety directions. O therwise,
serious injury and damage can occur.

Think safety first.

2. Keep propeller away from body parts, even when it
isn’t spinning, as it could be turned on by accident.
Beware of hair becoming entangled in the

propeller, especially while launching the

J-3 Cub BL PNP.

3. Do not fly when it’s too windy or you may lose
control and crash, causing injury or damage. Never
fly near people, vehicles, train tracks, buildings,
power lines, water, hard surfaces or trees. Never
allow any one to attempt to catch the airplane
while it’s in flight or serious injury can result.

4. Adult supervision is recommended for ages 14
and under.

5. Battery charging: Only use a battery charger
intended for use with the flight batter y. Never leave

charger unattended while charging. This will help
prevent overcharging. While charging, place the
battery on a heat resistant sur face. Do not lay it on
carpet or upholstery while charging.

6. Never cut into the battery charger or airplane wires
or serious injury can occur. Causing the
battery to “short out” (crossing negative and
positive bare wires) can cause fire, serious injur y
and damage.

7. Hold the plane securely, and keep all body par ts
away from the propeller when the flight batter y
is plugged in. When you finish flying the
J-3 Cub BL PNP, always unplug the battery before
you turn off the transmitter.

8. Never fly on the same frequency as another RC
vehicle in your area. The frequency of the

J-3 Cub BL PNP is shown on stickers on the back of

the transmitter.

Before first use, please refer to Chart A for BEC usage
and input voltage/cell count guidelines. You must
follow these guidelines for safe operation. If you are
using four servos with higher current draw, or more
than four servos for a quad flap option (for example),
you will need to disable the BEC. If you wish to disable
the BEC, you must remove the red receiver wire lead
and connector from the receiver lead housing, and
then insulate it properly to prevent shorting.

When operating with the BEC disabled, E-flite
recommends the use of a separate, high power,
external, BEC (like the Ultimate BEC), or receiver
pack and switch using the following items to ensure
trouble-free operation:

1. Expert 720mAh Ni-MH 4.8V receiver battery
(EXRB100), or similar

2. Expert Standard Switch (EXRA050), or similar

PLEASE READ THESE INSTRUCTIONS

IN THEIR ENTIRETY BEFORE USE

Before you connect your ESC and begin flying, take
a moment to look it over. The input power side has a
black (negative) and red (positive) wire along with a
female JST Connector. The motor side has three, 2mm
female gold bullet connectors.

The black and red wires with the female JST connector
will connect to your power battery. The red wire
connects to the red wire on your battery pack, the
black wire to the black wire on your battery pack. If
the wires are reversed, the ESC may be damaged. YOU

MUST ENSURE THAT YOU CONNECT THE BATTERY
POLARITY PROPERLY TO PREVENT DAMAGE TO
THE ESC. Reversing polarity will void your warranty, so

always double-check this connection. You may need to
solder a male JST Connector (EFLA242) to the battery
so it matches this speed control. The throttle lead
connects to the throttle channel on your radio receiver.

WARNING: For your safety, when checking the
startup function of the ESC or making programming
changes, please remove the propeller to prevent any
potential injury. You should always treat the motor
and propeller as live and dangerous,
remembering that it could start at any time, and
keep any body parts, clothing and tools clear of the
propeller arc. NEVER LEAVE THE BATTERY

CONNECTED WHEN NOT FLYING THE AIRCRAFT AND
ALWAYS REMOVE THE BATTERY FROM THE MODEL

Chart A

BEFORE CHARGING AND WHEN
FINISHED FLYING.

When flying in hot weather, we recommend checking
on the condition of the ESC, battery, and motor after
each flight, and you may want to consider letting the
electronic components cool to near ambient
temperature between flights.

We also recommend throttle management when
running near maximum levels of current draw. It is
not recommended that you fly an entire flight at full
throttle. If this is done, it is possible to cause
permanent damage to your motor, battery, and ESC.

Using Your 10-Amp Pro Brushless Controller:

This controller is very simple to use, and for safety, will
not arm the motor until the throttle stick has been
held in the Idle/OFF position for more than 1 second.
The controller will indicate the soft cutoff voltage
setting every time you plug the battery in by first
emitting a low, long tone, to show startup. You will
then hear 2 (for 2-cell Li-Po) or 3 (for 3-cell Li-Po)
medium length, mid tones to indicate the cell count
(or 7 beeps if 70% Smar t Cut is selected), helping you
to confirm the setting before every flight.

Connecting the ESC to the Motor:

The three wires from your motor connect to the three
female gold bullet connectors on the ESC. The order
of connection to the motor is not important; you can
plug any motor wire into any connector. If, when you
test the system, the motor runs back wards you can
simply unplug and switch any two of the motor wire
plugs connected to the ESC.

Mounting the ESC:

Choose a location that has good airflow and
offers good protection.

The plastic case area next to the small BEC heat sink is
designed to accept Velcro or 2-sided tape. Do not
cover the heat sinks as this will greatly reduce their
effectiveness.

Mount the ESC with a combination of Velcro,
2-sided foam tape, and/or tie wraps.

Starting Your Power System:

1. Turn on your transmitter and ensure the
position of the throttle stick is set to Idle/Off.

Specifications:

• Continuous Current: 10A

• Max Burst Current: 12A (15 sec)

• Length: 30mm (1.2 in)

• Width: 17.5mm (.7 in)

• Height: 10mm (.4 in)

• Weight: 10 g (.35 oz)

• Cells: 2-3S Li-Po or 6-10 Ni-MH/Ni- Cd

• Battery Input Leads: 20 AWG with JST Connector

• Motor Output Leads: 20 AWG with 2mm Female Gold
Bullet Connectors

** Sub-Micro Servos tested 4 at a time include E-flite S-60, and
S-75, JR 241, and ParkZone 3W servo.Some other brands of
servos have significantly higher current draw. Digital sub-micro
servos, micro, and mini-servos have higher current draw, use the
'standard servos' column. Always be sure to position the ESC for
maximum airflow since cooling can significantly aid in the
performance of the BEC.

2. Plug in the flight pack to the controller and
listen for the tones to indicate voltage cutoff.

3. After the controller has indicated the cell
count, you will hear a series of 3 medium
length rising tones to indicate the controller is
ready to fly.

4. When you move the throttle stick upward,
the motor will run. If you continue to move the
throttle stick upward to full throttle (high
position), the motor will run faster. If you lower
the throttle stick below the start-up position,
the motor will stop running.

5. Check servo motion as part of your preflight
check. It is very important you make sure
linkages are free-moving with no binding.

Entering the Programming Mode:

1. With the battery disconnected from the
controller, and the transmitter turned on, first
move the throttle stick to full throttle (>1.7ms)
position. Leave it in this position and then
connect the battery to the controller.

2. Wait for 5 seconds, and the ESC will give two sets
of fast ringing tones to indicate you have
successfully entered the programming mode.

3. Once you hear these tones, move the stick to
center (between 1.4 and 1.6ms), and the
controller will beep 1 time; this indicates
menu item 1.

4. The controller will now wait 5 seconds for you
to make your selection; your programming
options are either full throttle (>1.7ms),
or idle (<1.3ms).

5. When you have made a valid selection the
control will beep once with a lower tone, and
you can move the stick back to center for the
next menu item (2 beeps, 3 beeps and so on). If
you do not make a selection within 5 seconds,
the controller will move to the next menu item.

6. Please note that if you do not need to
program every menu item, you can simply exit
the programming mode after you have made
the required selec tions. You can do this by

moving the throttle stick straight to Idle, after
making your selection, or leaving it in the Idle
position if you made a no selection (for
approximately 8 seconds), until you hear one
set of 3 medium length rising tones that
indicate the controller has armed the motor, or
by simply unplugging the battery.

Remember, when in the programming mode:

Full Throttle = Stick Up
Idle = Stick Down

The default settings (from the package) for your
E-flite 10-Amp Pro ESC are as follows:

• 3S (9V) auto cutoff for Li-Po

• Brake Off

• 4-pole and greater timing (outrunner or
6-pole motors)

• Throttle input range set to Auto Select Mode

(1.2ms–1.8ms)

Programming Menu 1 – Voltage Cutoff:

Use this option to set the voltage at which the
controller will shut down the motor to prevent
damage to your battery, when it reaches the cutoff
voltage. You will know that your battery pack has
reached auto cutoff when you hear the motor
“pulse” repeatedly.

1. 3S Li-Po voltage cutoff – Full Throttle

2. 2S Li-Po or Ni-Cd/Ni-MH voltage cutoff – Idle

3. 70% Smart Cut soft cutoff (see below for

Smart Cut information)

NOTE: To access the 70% Smart Cut option, leave the stick at full
throttle for 7 seconds while in menu item 1, until 7 beeps are heard,
then continue through the program normally. This option will
activate the soft cutoff at 70% of star tup voltage. For example, if your
pack measures 10.0 volts at startup, then the soft cut will occur at 7.0
volts. The Smart Cut option will check the startup voltage every time
you plug the battery into the controller, so beware of using
partially charged packs, as the system cannot protect your Li-Po
batteries if you are using Smart Cut and connect a partially
charged pack.

You will know your battery pack has reached soft
auto cutoff when you hear the motor “pulse” repeat­edly. We recommend you land your model as
soon as you hear the motor pulse (indicating the pack
voltage has dropped to the cutoff voltage level) to
prevent over-discharge of the Li-Po battery

pack, and to prevent sudden power loss.

Programming Menu 2 – Braking:

This option gives you the choice to have the ESC stop
the propeller during flight (Brake on) or allow it to
windmill (Brake off ). Use the brake-on option
for gliders.

1. Brake Off – Full Throttle (>1.7ms)

2. Brake On – Idle (<1.3ms)

Programming Menu 3 – Timing:

Please refer to your motor instructions and
specifications for an indication of the number of poles.

1. 4-pole and greater motors timing
mode – Full Throttle

2. 2-pole motors timing mode – Idle

Programming Menu 4 – Throttle Input Range:

This option is to allow for proper operation of the ESC
with many different radios on the market. Most radios,
and all the computer radios we have tested, work well
with the auto-set option, but some radios have a wider
output range, and may give a more linear response
with the 1.1 to 1.9ms range. I f you feel there is too
much “dead” area in the stick movement near Full
Throttle, try adjusting the end points in your radio, or
change to the wider input range.

Be aware that if these settings are not correct, it may
be impossible to arm the controller. If this happens,
return the input range setting to the default auto

learning setting.
The auto setting option learns the minimum
position of your throttle (between 1.1 and 1.3ms)
and stores this value at each star tup, and then adds
a value of 0.6ms for the full throttle setting.

1. Throttle Range 1.1ms to 1.9ms – Full Throttle

2. Auto Select – Idle

Error Codes:

The controller will beep continuously if the input
voltage is below the cut voltage (beep...beep...beep)
when the battery is connected. Check the voltage
of the battery pack to see if it is correct, or the
programmed cutoff setting if the input voltage is
set incorrectly for the voltage of the pack
being used.

If you have trouble arming the controller (and the
throttle trim has been set to minimum), enter the
programming mode and try the auto setting in
Programming Menu 4 to see if it helps correct your
problem. If it is a computer radio, you may
alternatively increase your high and low throttle
ATV (endpoint) percentages.

Some systems including many Futaba* systems
may require the throttle channel to be “reversed” for
proper operation.
