change the flight characteristics.
A five-year lithium backup battery
prevents loss of memory in the event
that the battery discharges completely
or is removed.
CHAPTER 2: FEATURES
2.2 R770 RECEIVER
R770 (PCM Systems)
The R770 is a high-performance PCM or
single-conversion receiver with 10KHz
super narrow band ABC&W circuitry.
A narrow band ceramic filter for high-
signal selectivity assists in rejecting cross
modulations from other common radio
frequencies-e.g. R/C transmitters, local
paging systems. This receiver features
Direct Servo Control (DSC) for control of
surfaces without radio frequency output.
The receiver has low current
consumption.
The R770's Slimline design allows it to fit
into most model applications.

CHAPTER 4: BATTERY CHARGING
TRANSMITTER/RECEIVER 4.1
Note: It is imperative that you fully
charge both the transmitter and the
receiver battery packs prior to each
trip to the field. To do so, leave the
charger and batteries hooked up
overnight (16 hours). The first charge
should be approximately 20–24 hours
in order to fully charge both battery
packs to peak capacity.
The charger supplied with this system is
designed to recharge your batteries at a
rate of 50mAh for the transmitter and
120mAh for the receiver battery pack.
Transmitter Only
The center pin on all JR Remote Control
Systems is negative. Therefore, the center
pin on all JR chargers is negative, not
positive. This is different from many other
manufacturers' chargers and radio
systems. Beware of improper connections
based on "color-coded" wire leads, as they
do not apply in this instance. You must
make sure that the center pin of your JR
transmitter is always connected to the
negative voltage for correct polarity
hookup.
Important: Please note that the charging
polarity of the transmitter and
receiver are different.

CHARGER 4.2
The pilot lamps should always be on
during the charging operation. If not,
check to make sure that both the
transmitter and receiver are switched off.
Do not use the charger for equipment
other than JR. The charging plug polarity
may not be the same. Equipment damage
can result.
Do not use other manufacturers' after-
market accessories that plug into the
transmitter's charging jack. If you do, any
damage that results will not be covered by
warranty. If you are unsure of
compatibility issues with your radio, seek
expert advice to avoid possible damage.
During the charging operation, the
charger's temperature is slightly elevated.
This is normal.

4.3 ADVANCED DIGITAL TRIMS
The XP6102's digital trims also feature the
Direct Access display function. While at
the Normal display screen, if a trim lever
is moved, the screen will automatically
change to display the numeric value, as
well as the graphic position for the trim
being adjusted. The XP6102's Aileron,
Elevator, Throttle and Rudder trim levers
feature an audible center trim beep. This is
helpful in determining the trim levers
center position during flight.
Please also note that unlike conventional
mechanical trim levers, when the X-6102
transmitter is in the off position, no
changes can be made to the trim values
during transportation.

1.4 CONTROL STICK LENGTH ADJUSTMENT
To adjust the stick length, use the
2mm Allen wrench (supplied with your
XP6102 transmitter) to unlock the set
screw. Turn the wrench counterclockwise
to loosen the screw. Then, turn the
stick clockwise to shorten or
counterclockwise to lengthen. After the
control stick length has been adjusted
to suit your flying style, tighten the
2mm set screw. If you desire longer sticks,
JR offers a stick (JRPA047) that is

1.5 CONTROL STICK TENSION ADJUSTMENT
Remove the Ni-Cd battery and six
transmitter back screws as shown on the
previous page. Remove the transmitter
back, being careful not to cause damage
to any components.
Adjust each screw for desired tension
(counter-clockwise to loosen stick feel;
clockwise to tighten stick feel). When
adjusting the throttle ratchet tension,
make sure that the adjusting screw
does not touch the PC board after
adjustment is complete.

1.6 DIRECT SERVO CONTROL (DSC)
For proper DSC hook-up and operation:
1. Leave the transmitter power switch in
the Off position. The transmitter will not
transmit any radio frequency (RF) in this
position.
2. Plug the (supplied) DSC cord into the
DSC port in the rear of the transmitter.
3. The encoder section of the transmitter
will now be operational and the LCD
display will be lit.
4. Plug the other end of the DSC Cord
into the receiver charge receptacle. Turn
the switch harness to the On position.
Note: When you install the charging
jack, be sure to hook the charging
jack receptacle securely into the
switch harness charge cord.
Why you should use the DSC function:
1. The DSC enables you to check the
control surfaces of your aircraft without
drawing the fully operational 200mAh
from your transmitter battery pack.
Instead, you will only draw
approximately 70mAh when using the
DSC function.
2. The DSC function allows you to make
final adjustments to your airplane
without transmitting any radio signals.
Therefore, if another pilot is flying on
your frequency, you can still adjust your
aircraft and not interfere with the other
pilot’s aircraft.
Note: Under no circumstances should
you attempt to fly your aircraft with
the DSC cord plugged in! This
function is for bench-checking your
airplane only.

NECK STRAP ATTACHMENT 1.7
An eyelet is provided on the face of the
XP6102 transmitter that allows you to
connect a Neck Strap (JRPA023). This
hook has been positioned so that your
transmitter has the best possible balance
when you use the neck strap.
13XP6102 - Airplane Manual
BASE LOADED ANTENNA 1.8
An optional base-loaded antenna is
available for use with the XP6102
transmitter. It is considerably shorter than
the standard antenna. However, the base
loaded antenna cannot be collapsed for
storage in side of the transmitter. You must
also use an adapter (JRPA156) to attach
the antenna to your XP6102. The Base
Loaded Antenna (JRPA155) is made of a
flexible coil and is covered with a soft
plastic material. Your range will not be
affected when using the base loaded
antenna.
FREQUENCY NOTES/AIRCRAFT ONLY FREQUENCIES 1.9
The XP6102 transmitter employs a plug-in
crystal for the transmitter that is glued in
place at the time of shipment. Per FCC
regulation, the transmitter crystal should
only be changed by a certified technician.
Changing of the transmitter crystal by a
non-authorized technician could result in
a violation of FCC rules.
The XP6102 can transmit in either Pulse
Code Modulation (PCM) or Pulse Position
Modulation (PPM, commonly referred to
as FM).
Be certain to observe the following
guidelines:
1. Do not operate your transmitter when
another transmitter is using the same
frequency, regardless of whether the
second transmitter is PCM, PPM (FM) or
AM. You can never operate two
transmitters on the same frequency
simultaneously without causing
interference.
2. For operation of your X-378 with
additional receivers, you should refer to
the receiver compatibility chart. The chart
is located in the Modulation Selection
Section of this manual.
Aircraft-Only Frequencies
JR Transmitters and receivers are available
in 72MHz frequencies in the United
States for use with model aircraft.
Employing 72MHz frequencies does not
require a special operator’s license from
the Federal Communications Commission
(FCC).
* A chart for all available frequencies is
located on page xxx of this manual.

2.1 INSTALLATION REQUIREMENTS
It is extremely important that your radio
system be correctly installed in your
model. Here are a few suggestions
installing your JR equipment:
1. Wrap the receiver in protective foam
rubber that is no less than 3/8 inch thick.
Secure the foam to the receiver with #64
rubber bands. This protects the receiver
in the event of a crash or a very hard
landing.
2. The servos should be mounted using
rubber grommets and brass eyelets to
isolate them from vibration. Do not over-
tighten the mounting screws; this will
negate the vibration absorption effect of
the rubber grommets. The following
diagram will assist you in properly
mounting your servo.
The brass eyelets are pushed from the
bottom up in the rubber grommets.
When the servo screw is tightened
securely, it provides the proper security
as well as the proper vibration isolation
for your servo.
3. The servos must be able to move freely
over their entire range of travel. Make
sure that the control linkages do not
bind or impede the movement of any of
the servos.
4. Mount all switches away from the
engine exhaust and away from any high
vibration areas. Make sure the switch
operates freely and is able to operate
over its full travel.
5. Mount the receiver antenna firmly to
the airplane to ensure that it will not
become entangled in the propeller or
control surfaces.

5.3 MODEL SELECTION
The XP6102 system offers memory for ten
completely separate models. Therefore,
it is possible to have a mixture of
helicopter and airplane setups retained
in memory. It is also recommended that
the Model Name Entry function be used
in conjunction with each model setup.
Another very useful function of the Model
Selection function is the ability to set
one aircraft up several different ways.
This is helpful when multi-task
performance is desired.
