RECEIVER FEATURES
R700 Slimline Receiver
• The R700’s extremely compact “slimline” design
allows it to fit easily in limited spaces.
• An independent laboratory ranked the R700
receiver with JR’s patented ABC&W circuitry as
one of the best receivers ever tested in terms of
3IM, 2IM, adjacent channel rejection, signal-tonoise ratio, and on-channel capture point.
• A special “unwanted interference limiter” ignores
signals outside of the R700’s band width when
the receiver is on and the transmitter is off.
•
•
•
The limiter also prevents servos from random
glitching when other transmitters are operating
in close proximity.
• The electrical circuitry in the R700 is state-of-theart surface mount technology (SMT). These SMT
components draw less current, thus increasing
flying time. Flush mounting of these components
also reduces the risk of vibration, wear, and
damage.
• The R700 is compatible with all JR FMtransmitting radios.

INTRODUCTION 4: Battery Charging
4.1
TRANSMITTER / RECEIVER
It is imperative that you fully charge both the
transmitter and the receiver battery packs prior to
each day of flying. For the initial charge, leave the
charger and batteries hooked up for 20-24 hours in
order to fully charge both battery packs to peak
capacity. For subsequent charges, leave the charger
and batteries hooked up overnight (approximately
16 hours).
The charger supplied with this system is designed to
recharge your transmitter battery at a rate of 50mA.
The receiver battery pack will charge at 50mA for the
600mAh 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 any other manufacturers’ chargers and radio
systems. Beware of improper connections based
on “color code” wire leads as they do not apply
in this instance. You must make certain that the
center pin of your JR transmitter is always
connected to the negative voltage for correct
polarity hookup.

CENTER
PIN IS
NEGATIVE
OUTSIDE IS POSITIVE
CHARGER PIGTAIL FOR TRANSMITTER

CHARGER PIGTAIL FOR RECEIVER
RED–POSITIVE / BROWN–NEGATIVE / ORANGE–SIGNAL
CHARGER
The pilot lamps should always be on during the
charging operation. If they are not, make sure you
have turned off both the transmitter and receiver.
Do not use the charger for equipment other than JR.
The charging plug polarity may not be the same, and
equipment damage may result.
10
RIGHT SIDE OF TRANSMITTER
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
compatibilities with your radio, seek expert advice
before doing anything to avoid possible damage.
During the charging operation, the charger’s
temperature is slightly elevated. This is normal.

TRANSMITTER REAR
Note: Your transmitter has a 5-year lithium battery
to protect your preprogrammed data against main
transmitter battery failure. If your system reads 0.0V
or has an unfamiliar display (service mode), or your
data resets to the factory defaults, return your
transmitter to Horizon Service Center (see page 28)
for a lithium battery replacement.

DIRECT SERVO CONTROL (DSC)
For proper DSC hook-up and operation:
1. Leave the transmitter power switch off. The
transmitter will not transmit any radio
frequency (RF) in this position.
2. Plug the optional DSC cord (JRPA132) 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 on the
switch harness.
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 aircraft.
Note: Under no circumstances should you
attempt to fly your aircraft with the DSC cord
plugged in! This feature is for bench checking
your aircraft only.
Note: When installing the optional charging
jack (JRPA024), 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 airplane without drawing the
fully operational 200mAh from your transmitter
battery pack. Instead, you will only draw 70mAh
when using the DSC function.
Note: You will need to purchase (separately)
both the DSC cord (JRPA132) and the JR Deluxe
Switch Harness (JRPA001) to make use of the
XF631 DSC function.
1.6
NECK STRAP ATTACHMENT
There is an eye hook on the front of the transmitter
for attaching an optional neck strap (JRPA023). The
eye hook is precisely positioned (see Section 1.1)
14
A - Charge Cord/DSC Receptacle

INSTALLATION REQUIREMENTS
It is important to correctly install the radio system in
your model. Please read and carefully follow the
suggestions listed below.
do not impede servo travel. A stalled servo will
drain the battery pack within a few minutes.
5. Before installing servo output arms, make sure
the servo is in its neutral position.
6. In the case of gas-powered model aircraft, mount
the receiver power switch on the side of the
fuselage opposite the muffler to protect the
switch from exhaust residue. With other types of
models, mount the switch in the most convenient
place. Make sure that the switch operates freely
and is capable of traveling its full distance.
7. With your model sitting on the ground and the
transmitter antenna collapsed, check that your
system works at a distance of 75 to 100 feet.
1. For added protection, wrap the RX and the RX
NiCad in foam rubber that is at least 1/4” thick.
2. Run the RX antenna through the fuselage and
make sure it is fully extended. Never cut or
bundle your RX antenna — this will decrease
range and performance.
3. Rubber servo grommets are included with your
radio system and should be installed in the servo
flanges. The servos should then be mounted on
either hardwood rails or a plywood tray with the
mounting screws provided. Do not overtighten
the mounting screws. The flange of the brass
eyelets should face down (toward the wood).
4. All servos must be able to move freely over the
full range of their travel. Make sure the linkages

WING TYPE SELECTION • System Mode
Flaperon, V-tail, and Delta mixing are available for
specialty aircraft that require those functions. The
flaperon feature mixes flaps with ailerons so the
ailerons can be drooped for takeoffs and landings
while still functioning fully as ailerons. V-tail mixing
combines rudder and elevator for V-tail operations.
The Delta wing function allows the aileron to also act
as the elevator, while retaining independent use of
both functions. The Delta wing function allows the
ailerons to also act as the elevator, while retaining
independent use of both functions.
Flaperon Setup
When using flaperon mixing, two servos (one for
each aileron) must be used. Connect the left aileron
servo to channel #6 (Flp/Aux 1) and the right aileron
servo to channel #2 (Aile) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
still available for each of the channels. Use sub-trims
for individual neutral adjustment.
Note: When flaperon is selected, it is necessary
to reduce the travel adjust values of channel #6
0% in each direction to prevent servo over-travel
(binding). Please refer to section 7.3 for travel
adjust information.
V-Tail
V-Tail mixing requires two servos. Connect the left
tail servo to channel #3 (Elev) and the right tail servo
to channel #4 (Rudd) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
available for each servo. Use sub-trims for individual
neutral adjustments described in Section 7.2. V-Tail
elevator travel is adjusted by elevator and rudder
travel adjust.
Delta Wing Mixing
Delta or elevon mixing, as it is commonly known, is
the final wing mixing selection in your XF631. This
style of aircraft also employs two wing servos.
However, in essence, there is not an elevator present.
Instead, at an elevator stick input, the two wing
servos function in conjunction with one another in
the same direction to create an up/down movement
of the aircraft. Also, when an aileron control is given,
the two wing servos move in opposite directions to
function as ailerons as well.

DUAL RATE • Function Mode
Dual rate is available for the aileron and elevator
channels. The purpose of this function is to allow for
in-flight selection of two preset servo travels for each
of these channels. The amount of travel is adjustable
from 0-125%. The factory settings for both switch
positions (0 and 1) is 100%. Either position may be
selected as the low or high rate by placing the
switches in the desired position and adjusting the
value for that position. Different types of maneuvers
require varying amounts of control movements. Snap
rolls require large control movements, while smooth
maneuvers like long slow rolls are best performed
with smaller control movements. Dual rates allow
you to change the control movements in flight at the
flip of a switch. This allows you to execute maneuvers
requiring both radical control movements and small
control movements during a single flight.

SUB-TRIM • Function Mode
Sub-trim is an electronic trim that is available for
each of the 6 channels. Sub-trim is particularly useful
as it allows the digital trim levers to be returned to
their neutral positions by adjusting /changing the
servo’s neutral position electronically, without the
need to mechanically adjust the specific control
linkage. This allows the same digital trim lever
settings between the two models you can control
with this radio system. Sub-trim can also allow
additional trim travel when digital trims do not
provide enough movement.
Note: It is recommended to use as little sub-trim
as possible for adjustment. If more that 20–30
points are required, is it suggested that a
mechanical linkage adjustment be performed.
Note: Prior to making final subtrim adjustments,
please check to make sure that the digital trim
values for aileron, elevator, and rudder are set to
the neutral position. Throttle trim value should
be set to the -40 position.

IMPORTANT INFORMATION
GENERAL NOTES
Radio controlled models are a great source of
pleasure. Unfortunately, they can also pose a potential
hazard if not maintained and operated properly. It is
imperative that you install your radio control system
correctly. Additionally, your level of piloting
competency must be high enough to ensure that you
are able to control your aircraft under all conditions. If
you are a newcomer to radio controlled flying, please
seek help from an experienced pilot or your local
hobby shop.
Listed below are some safety “Dos and Don’ts” that
must be followed by all pilots:
• Ensure that your batteries have been properly
charged prior to initial flight.
• Keep track of the time that the system is turned
on so that you will have an idea of how long you
can safely operate your system.
• Perform a ground range check prior to the initial
flight of the day. See the “Daily Flight Checks”
section below for information on how to do so.
• Check all control surfaces prior to each takeoff.
• Use frequency flags.
• Do not fly your model near spectators, parking
areas, or at any other area that could result in
injury to people or damage of property.
• Do not fly during adverse weather conditions.
Poor visibility can cause disorientation and loss
of control of your aircraft. Strong winds can cause
similar problems.
• Do not fly unless your frequency is clear.
Warning: Only one transmitter at a time can
operate on a given frequency. If you turn on your
transmitter while someone else is operating a
model on your frequency, both pilots will lose
control of their models. Only one person can use a
given frequency at a time. It does not matter if it is
AM, FM, or PCM — only one frequency at a time.
• Do not point the transmitter antenna directly
toward the model. The radiation pattern from the
tip of the antenna is inherently low.
• Do not take chances. If at any time during flight
you observe any erratic or abnormal operation,
land immediately and do not resume flight until
the cause of the problem has been ascertained
and corrected.
DAILY FLIGHT CHECKS
1. Check the battery voltage on both the transmitter
and the receiver battery packs. Do not fly below
9.0 volts on the transmitter or below 4.7 volts on
the receiver. To do so can cause a crash of your
aircraft.
Note: When you check these batteries, ensure that
you have the polarities correct on your expanded
scale voltmeter.
2. Check all hardware (linkages, screws, nuts, bolts)
prior to each day’s flight. Be sure that binding
does not occur and that everything is properly
secured.
3. Ensure that all surfaces are moving in the proper
manner.
4. Perform a ground range check before each day’s
flying session. The range check should be as
follows:
XF631 MANUAL • IMPORTANT INFORMATION
• Do not extend the transmitter antenna at this
time. Turn the transmitter on.
• Turn the model on.
• Slowly walk away from the model while moving
the control surfaces. The aircraft should function
properly at a distance of 75–100 feet.
5. Just prior to starting your aircraft, turn off your
transmitter and then turn it back on. Do this each
time you start your aircraft. If any critical switches
are on without your knowledge, the transmitter
alarm will warn you at this time.
6. Ensure that all trim levers are in the proper
location.
7. Check to be sure that all servo pigtails and switch
harness plugs are secured in the receiver. Also,
make sure that the switch harness moves
completely in both directions.
