INTRODUCTION
JR’s new G5000T Extreme Tail Lock Gyro represents the very latest in both head-
ing hold and rate gyro technology. Based from JR’s outstanding G3000, the G5000T
incorporates the same contest winning rate gyro technology, while adding the new
“extreme tail lock” heading hold mode. This new “tail lock” provides the 3D helicop-
ter pilot with a heading hold system that will allow the pilot to push both their flying
skills, as well as their equipment to the extreme.
The G5000T, combined with JR’s 8700G Super Servo, offers superior “holding
power” in all conditions and is unequaled by anyother gyro system. The G5000T’s
advanced M.P.C. (Multi Pulse Control) system has a high frequency output that
allows theG5000T to react up to three times faster than current Piezo gyro systems
on the market.
SERVO SELECTION
JR’s G5000T must be used in conjunction with JR’s 8700G Super Servo or 8417
Digitalservos. Theseservos feature an ultra-quick response and transit time, and
their total travel is specifically matched to give the best possible resolution when
used with the G5000T. These servos also feature special “alloy” servo gears
designed to handle the extreme torque loads that the G5000T can produce during
flight. It is not recommended that plastic geared servos beused, as these gears can
possibly fail during flight due to the extreme demands the G5000T.
HELICOPTER TAIL ROTOR SYSTEM
Important: Becauseof the highly active/aggressive characteristics of this G5000T,
heavier than normal loads are placed on the tail rotor drive train. Take special note to
ensure that the main drive gear system and tail rotor gear box is in good working
order with the correct gear mesh and unworn teeth. Be sure it is properly greased
with all screws secured with Locktite®, etc.
On Miniature Aircraft X-Cell series of helicopters, a heavy-duty front tail rotor tune
up kit is recommended (part # MIN0832). When using the G5000T in a JR belt-driv-
en tail rotor helicopter such as the Ergo 60 or Vigor, it is recommended that the
optional JR aluminum tail pulleys be installed for maximum performance
(JRP960322 front, JRP960323 rear). The useof aluminum pulleys will greatly
reduce tail belt slippage as compared to the standard plastic pulleys. It is recom-
mended that the tail belt be checked after each flying session. If worn or missing
teeth are discovered, replace the tailbelt as needed.
Pleasealso note that due to theG5000T’s aggressive nature, the G5000T should
not be installed in a model that utilizesa “PIANOWIRE” tail drive system, as failure
can occur.
MAXIMIZING THE G5000T
Note: The G5000T Piezo gyro’s operational features and functions are very differ-
ent from any other type of gyro. The adjustments, including travel adjust, exponen-
tial, dual rates, tail rotor compensation values, gain values, and endpoint limits will
be very different from your previous normal settings. Do not install the G5000T in
your helicopter using your current setup. The capabilitiesof this gyro are much
greater; therefore, the adjustment values will bedifferent, and you must adjust them
correctly to realize the system’s full potential.
Carefully read this instruction manual and be sure you fully understand and fol-
low each segment before your first flight.
INSTALLATION
When deciding where to mount the gyro sensor, consider the criteria below:
Vibration
JR’s G5000T is as much as 30 times more sensitive and responsive than other
gyros. Because vibration is motion, the G5000T Gyro senses even minute vibrations
and acts upon them, sending the rudder servo an opposing command. Foroptimum
results, it’s imperative that your helicopter is as vibration-free as possible. All rotat-
ing components (e.g., main gear, head, tail rotor, blades, clutch, etc.) should be in
perfect balance. Equally important, the engine should run smoothly and consistently.
Spending the extra time to ensure that your machine is running perfectly will allow
the gyro gain to be turned up higher, more effectively holding the tail.
Temperature
The Piezo sensor is sensitive to drastic changes in temperature. Note that the
case features a matte chrome finish that is designed to reflect heat. When mounting
the gyro sensing unit, be sure that it is located away from the engine and exhaust
system so the heat does not transfer to thesensing unit. Also, when subjecting your
helicopter to temperature changes (e.g., going from your warm car to the cold out-
doors), allow the gyro’stemperature to stabilize for about 10 minutes before flying.
Installing the Gyro Sensor
Thoroughly clean the bottom of the gyro sensor and the mounting area with rub-
bing alcohol. Use one layer of the supplied double-sided tape to securely mount the
sensor in position.
Note: Do not use thick foam tape or multiply layers of double-sided tape as is
common practice with other gyros. The G5000T’s sensor is vibration/shock mounted
inside itscase via a rubber/air dampening system, and no further vibration isolation
is necessary.
Installing the Amplifier
Using the 1/4” or thicker foam, wrap the amplifierand the receiver together, mak-
ing sure that at least one thickness of foam is between the receiver and amplifier.
Fasten the receiver and amplifier to the radio tray using rubber bands, making sure
they are securely held in place. If space restrictions don’t permit the amplifier and
receiver to be mounted together, wrap them individually in foam and mount each in
a convenient location. Use an optional servo extension lead if necessary.
CONNECTIONS
Step 1: On the gyro amplifier, locate the lead marked “RUDD”. Connect this lead to
the rudder channel in thereceiver.
Step 2: On the amplifier, locate the lead marked “AUX 3.” Note that it has a white
connector for identification. When using a JRPCM-10, 10S, 10SX, 10SXF or 10X
radio system, connect this lead to the Aux 3-channel in the receiver. For JR 8103
systems, connect this lead to the Aux2-channel.
Note: When using this gyro with other radios like the JRXP652 the Aux 3 lead
must be connected to the appropriate channel — the one you use to alter the gain.
For example, if you want to use the gear switch to alter the gain, plug the Aux 3 lead
into the gear channel and use the travel adjust and sub-trim function to achieve the
desired gain in both switch positions.

Step 3: On the amplifier, locatethe SV (Servo) receptacle. Plug the rudder servo into
thisreceptacle, noting the correct polarity as indicated by the shape of the plug, as
well as the wire color.
Tail Lock™ Selection/Connection
The G5000T offers several methods to access and use the tail lock function.
Note: If you’re using a 6- or 7-channel system, you must install theG5000T as
detailed in Option 1.
Option 1: Tail Lock Mode or Rate Mode Always On
If you choose to havethe G5000T function in either tail lock or late mode only,
simplymove the tail lock switch located on the amplifier to the desired position(On
for tail lock, OFF for rate mode). With this option, it is not necessary to connect the
black SEL Aux 2 connector. Please note that with this method, it is not possibleto
access both the tail lock and rate modes as only one Aux channel is being used.
Quick Start
Option 1 is a quick way to get up and flying with your G5000T, as it’s the easiest
to set up. If you select the option to have the tail lockmode on, it will not be neces-
sary to use any form of tail rotor compensation, further simplifying the initial setup.
Option 2: Remote Rate and Tail Lock Mode Access
Connect the black SEL Aux 2 connector from the amplifier to the following chan-
nel on your receiver:
JR PCM 10 series (9- and 10-channel systems): Gear (Channel 5)
JR XP8103 series (8-channel systems): Gear (Channel 5)
This option will allow both thestandard rate and tail lock modes of the G5000T to
be remotely selected during flight via the gear switch.
This method will also allow for the use of an optional program mix that will allow
the G5000T’s modes to be selected via the Aux 3 gyro gain function. This method
will also enable the G5000T’s modes to be linked to the flight mode switch.
INITIAL RADIO SETUP
The G5000T Gyro is much more responsive than a standard piezo gyro, and it
can sense and correct for rotation rates at over 720˚ per second (standard gyros are
limited to approximately 250˚ per second). Because of this, the travel adjust and
exponential values can be much different than they are with other gyros to obtain the
optimum feel and rotation rates.
Travel Adjust
Set the rudder’s travel adjustment to maximum right and left. If you’re using a JR
PCM-10/10S/10SX, set the travel adjustment to 150% left and 150% right.
Dual Rates
The recommended starting points for dual rates are:
Flight Mode Maneuver Dual Rate Value
Normal Hovering 60%
Flight Mode 1 540 stall turns 100%
Flight Mode 2 Standard aerobatics 60%
Exponential
Because a very large stroke isused (150%), the control sensitivity around neutral
is high. Exponential is necessary to reduce the sensitivity around neutral. The rec-
ommended starting points of exponential are:
Flight Mode Maneuver Exponential Value
Normal Hovering 60%
Normal Hovering 40%
Flight Mode 1 540 stallturns 60%
Flight Mode 2 Standard aerobatics 60%
Note: After you have gained some experience and flight time, you can alter travel
adjust, dual rate, and exponential values to suit your flying style.
SETUP AND ADJUSTMENT
The G5000T Piezo gyro gives true linear feedback response of rotation rates from
as little as 1˚ per minute up to over 720˚ per second. Because of its high response
rate and authority, the adjustment values (e.g., travel adjust, exponential, tail rotor
compensation, etc.) will be very different from what you’re used to.
Following is the step-by-step procedure that must befollowed to achieve the
highest level of performance from your gyro system.
Step 1: Unhook the tail rotor linkage at the rudder servo and swing the servo arm
out of the way. Lightly grasp the tail rotor pushrod at the servo end and move the
tail rotor throughout its entire stroke. The tail rotor linkage should move through
its full range smoothly with very little friction and no rough spots. Work on the
linkage system until this is achieved.
Step 2: On your transmitter, reset all the rudder trimmers (sub-trim, trim offset,
stunt trim, mechanical trim lever, etc.) to zero or center. Set the throttle/pitch stick
at exactly the hover position (normally 50%). Turn off or zero out both the revolu-
tion mixing (up and down) and the acceleration mixing.
Step 3: Turn on your receiver and allow the helicopter to remain totally motionless
for three seconds. A bright LED light on the amplifier will come on after three sec-
onds, indicating the gyro has digitally stored the zero rotation value.
Step 4: Install the servo arm
90˚ to the tail rotor pushrod
(see diagram). You may find
that the splines are slightly
offset on your servo, not
allowing an exact 90˚ position-
ing. If so, rotate the servo arm
to another arm position and
try again. Secure the arm in
place with the screw provided.
Attach the pushrod to the arm
at approximately 16 mm out
from the center. Later, we will
optimize this distance through flight testing.
Step 5: Be sure the rudder servo is moving in the correct direction. A right servo
command should move the nose of the helicopter to the right. (If you’re unsure,
seek help from someone with more experience.) Reverse the servo direction in the
transmitter’s programming if necessary.
Step 6: Give a right rudder command and note the direction the rudder servo
moves (clockwise or counterclockwise). Then pick up the helicopter and quickly
rotate the nose to the left. The servo should move in the same direction as it did
when you applied right rudder (clockwise or counterclockwise). If the rudder servo
rotates in the opposite direction, move the reverse switch located on the amplifier
in the opposite direction.
Step 7: With the G5000T in tail lock mode (green LED), check to insure that the
servo will remain in the neutral (centered) position. If the servo “Drifts” or slowly
moves in either direction, enter the sub trim function of your radio system and add
a sub trim value as needed until the servo will remain in the neutral position, with
no tendency to drift in either direction.
TAIL ROTOR LINKAGE ADJUSTMENT
With theservo arm positioned at 90° degrees to the control rod, adjust the over-
all length of the tail control rod so that the tail pitch mechanism is at the center of its
travel limits. It’s also necessary to insure that the tail rotor blades have the proper
degree of pitch in the neutral position to maintain a stationary hover. Approximately
5° is agood starting point. The final pitch of the tailblades will need to be fine tuned
during test flights byadjusting the tail linkage mechanically.
Adjusting the Endpoint Limiters
With the travel adjust set to 150%, you will notice that moving the rudder stick to
its extremes may bind (over-stroke) the tail rotor linkage. JR’s G5000T has a unique
feature that electronically limits the maximum servo travel, preventing binding/over-
stroking of the rudder linkage — but it has no effect on the maximum control
authority during high speed pirouettes.
Note: Locate the tail lock switch on the G5000T amplifier, and move the switch to
the OFF position. This will allow for proper servo end point travel adjustment. Reset
the switch to the desired position once the endpoint limiter has been adjusted.
With your radio system on, give a full right ruddercommand. Using a small
straight screwdriver, adjust theservo travel limiter while noticing the rudder servo.
Adjust the pot until the servo has maximum available travel but no binding occurs.
Give a fullleft rudder command and adjust the limiter as needed to the point just
before the servo binds. This sets the maximum available travel and eliminates link-
age binding/over-stroking while the helicopter is on the ground.
Note: You will notice that with the travel limiters adjusted, it appears that the rud-
der stick only works the servo throughout half its stroke. This is normal! During
flight, the gyro provides feedback to the servo that combines information about its
rotation rate and the gain setting that gives proportional rotation rates throughout
the rudder’s stick travel.

Important: When properly adjusted, it’s normal for the rudder stick to only affect
the rudder’s position around
the center half of its stroke.
During flight, the gyro senses
the rotation rate of the helicop-
ter, and the rudder servo works
normally throughout its total
stroke.
RATE/TAIL LOCK
MODE SELECTION
Thereare two setup options
available when installing the G5000T.
Note: While in tail lock mode, a slight change in the neutral position of the servo
may occur while the model is in a stationary position. In addition, when the servo is
moved to the extreme left/right position and released, the servo will slowly move
back to theneutral position.
These movements are completely normal and are caused by the Angular Velocity
Command Control System of the G5000T. These movements only occur while the
model is stationary. In flight, these movements do not occur.
OPTION 1: Tail Lock or Rate Mode Always On
(Mandatory with 6-channel systems)
Step 1: Movethe tail lockswitch on the gyro amplifier tothe desired position (ON
for tail lock mode, OFF for rate mode).
Step 2: Turn the radio system on and confirm that the G5000T is in the desired
mode (red LED: rate mode, green LED: taillock mode).
Note: If the tail lock mode is selected, make sure that all tail rotor mixing values
in the radio program have been reset to the factory default (0) position.
OPTION 2: Remote Tail Lock and Rate Mode Access
(Available only with 8 and 10 channel systems)
Step 1: Move the tail lock switch on the gyro amplifier to the on position.
Step 2: Verify that the mode remote select lead from the amplifier is connected to
the desired Aux channel (Aux 2 or Gear).
TAIL LOCK/ RATE MODE PROGRAMMING
Tail Lock Mode Programming(Option 2)
The programming shown below only applies if Option 2 was selected from the
previoussections. The programming indicated in this section only applies to 8- and
10-channel systems.
If you have selected Option 1 with tail lock always ON, proceed to the flight trim-
ming section.
If you have selected Option 1 with rate mode always ON, proceed to the Gyro
Gain section of these instructions.
JR 10 Series Systems
Step 1: Access a standard program mix (code 51-54) and assign a mix from Aux 3
(Ch 8) to Gear (Ch 5). This will make Aux 3 the master and Gear the slave channel.
Press “ENTER” and select “NO” for servo hold.
Step 2: While at the
second screen, press
the “PAGE” key to
access the third screen.
Select the desired flight
modes for the Tail Lock
function to be active by
pressing the “SEL” key
below each flight mode
box as shown below.
In this example, we have selected flight modes 1 and 2 to be in tail lock mode. All
other modes, unless activated, will be set to the standard rate mode.
Note: Check to insure that all tail rotor mixing values have been reset to 0 for the
flight modes that tail
lock mode will be used.
Step 3: Press the
“PAGE” key again to
return to the second
screen. Set the mix
value located in the
shaded box to - 100 as
shown at right.
Next, activate the G5000 and while watching the LED indicator on the amplifier,
move the flight mode and throttle hold switch through their positions to check that
the G5000T is changing to the desired modes (red for rate, green for tail lock).
If the G5000T does not move to the desired modes, check to insure that the prop-
er modes have been selected in the previous screen. If this information is correct,
try reversing the value in the shaded box from -100 to +100 and retest.
On JR 10 series systems, please also check to insure that the gear switch has
been inhibited through code 17 function
select. If the gear switch is active, the
G5000T will not change modes correctly
as described.
JR 8103 Systems
Step 1: Access Program Mix 3 from the
function mode and set the values as
shown in the screen at right.
Make sure that the switch position (SW) is set to F-S12. This indicates that the
mix will be activated when the flight mode switch is moved to positions 1 or 2 only.
Note: For proper operation, check to insure that all tail rotor mixing values have
been reset to 0 for the flight modes that tail lock mode will be used.
Step 2: Turn the system on and whilewatching the LED indicator on the amplifier,
move the flight mode switch. The LED should change from red (rate) to green (tail
lock) as the flight mode switch is moved. Set the rate or tail lock modesto the
desired flight modes. Our example shows the selection of rate mode for hover and
throttle hold, and tail lock mode for stunt modes 1 and 2.
GYRO GAIN SETTINGS
Adjust the gyro gain of yourradio system as follows:
JR 10 Series systems
Step 1: Access the gyro
gain function (code 44).
Step 2: Press “SEL”
until“Auto” appears on
the screen.
Step 3: Set the gain val-
ues as shown:
Note: For this exam-
ple, gain value 2 will not
be used.
Step 4: Press “PAGE”
and select the gain val-
ues for each flight mode as shown.
JR 8103 Series Systems
Step 1: Access the gyro gain (Gyro Sens)
function from the function mode.
Step 2: Press the + or - key until “AUTO” appears on the screen.
Step 3: Press “SEL” twice and select the following: NORM:0, STUNT:1
Step 4: Set the gain value as shown in the screen.
All other radio systems (JR 622,642, non JR systems)
Step 1: Access the travel adjust function of your system.
Step 2: Confirm the gear switch position as compared to thetravel adjust values on
the screen, and set the travel values for theGear channel (5) as follows:
Position 1 (Hover Gain): +90, Position 2(Stunt Gain): -20
Step 3: Turn the system on and verify that the gain valueincreased and decreases
when the gain switch is moved.
Note: All gain values shown in this section are initial starting values only. Gain
values can sometimes vary greatly due to the particular model, gear ratios, etc. Final
gain values can only be established after test flying. Please refer to the flight trim-
ming section of these instructions for more information.
TAIL ROTOR MIXING (RATE MODE ONLY)
Tail Rotor Mixing
While in rate mode only, the G5000T requires a small amount of tail totor mixing
to achieve maximum performance. Tail Rotor Mixing should never be used with the
G5000T in tail lock mode, as this mixing will cause the G5000T to be unable to
achieve and locate the correct neutral position for the servo.
Note: Due to the many variables involved with each different helicopter (engine,
blades, gear ratios, rotor rpm, etc), the values shown are initial starting values only.
Final mixing values can only be achieved by test flying the model.

FLIGHT TRIMMING
Tail Rotor Trim Adjustment
If you have chosen to use the G5000T in tail lock mode only, proceed to the gyro
gain adjustment section.
On the first test flight, it may be necessary to adjust the trim of the tail rotor if the
model pirouettes slowly in either direction and to hover themodel with the G5000T
in the standard rate mode.
As with all heading hold type gyros, make any tail trim adjustments in rate mode
by adjusting the tail rotor control rod mechanically.
Do not usesub trim or the transmittertrim to make these fine trim adjustments,
as this will cause an out of trim situation when the tail lock modeis in use.
Adjust the tail trim by lifting the model into a stationary hover, and note the direc-
tion the mode pirouettes. Land the model and adjust the tail control rod length as
needed. Continue this procedure until the heli will remain in a stationary hover, with
the tail remaining straight. Once this adjustment has been made, the G5000T can be
returned to tail lock mode if desired.
Note: While in tail lock mode, the G5000T will automatically establish the correct
neutral position of the tailrotor, without the need to re-adjust the linkage.
GAIN ADJUSTMENT
Hover
Lift the Heli into a stationary hover, whilelooking for any side to side movement
(hunting) of the tail rotor (yaw axis). If the model displays a Hunting tendency,
reduce the gain value by 5% and retest. Reduce the gain as needed until the model
will maintain in a stationary hover without hunting.
If the gain value is below 70% in hover, move the control ball in 1 hole on the tail
rotor servo arm and retest. If the gain value reaches 100% and no hunting occurs,
movethe control ball out 1 hole on the servo arm and retest.
The ideal gain setting when using a rotor rpm of between 1300 and 1400 rpm is
in the range of 90-95% gain. This will indicate that the control system has been set
to the optimum mechanical settings.
Forward Flight (Stunt)
From a hover of at least 15’ high, move the flight mode switch to thestunt posi-
tion, and begin to transition into a very slow forward flight. If hunting occurs, move
the flight mode switch back to the normal position and land the model. Reduce the
Gain by 5% and re-test. Continue this procedure until all hunting is removed with the
model at full forward speed. The final gain value should be in the range of 55-80%.
If the gain value is below 50%, move the control ball in 1 hole on the tail servo arm
and retest. If the gain value is above 80%, move the control ball out 1 hole on the
tail servo arm and retest. These values are based on a main rotor rpm in the range
of 1650 — 1750 rpm.
PIROUETTE RATE BALANCING
(Experienced pilots only)
Lift the model into a stationary hover. If you are comfortable, perform a full stick
pirouette to the left, and then to the right while noting the speed in which the model
rotates. If the model rotates more quickly in one direction that the other, adjust the
travel adjust down on the fast side and retest. When completed, the model should
pirouette at an equal rate in both directions.
Tail Rotor Blade Length
In most cases, choosing the correct tail rotor blade length can play a big part in
the overall performance of aGyro.
As a starting point, a 60-size heli with a 4.93 to 5.18 tail gear ratio performs very
well with a tail rotor blade length of approximately. 95 mm. We recommend NHPtail
rotor blades (NOH195) for their superior rigid and overall performance.
When stopping after a pirouette, if the model displays a“rebounding” motion in
one or both directions, this is generally caused by the tailblade length. Lengthen or
shorten the tail blades until this rebounding is removed. Since there are many vari-
ables that can also cause rebounding (rigidity of the helicopter frame and tail boom,
etc), proper adjustment can only be achieved through test flying.
TAIL LOCK VOLUME ADJUSTMENT
Locatedon theG5000T amplifier you will find apot in the tail lock system section
labeled “ADJ.” This pot is used to maximize the efficiency of the Tail Lock mode for
your particular model and installation. This pot comes factory preset to the 50%
position, which works well for most models.
After all flight trimming has been completed and you become comfortable with
the flight performance of the G5000T, you can alter the settings of this pot to further
maximize performance. Moving the pot counterclockwise reduces the tail lock sensi-
tivity, while clockwise increases the sensitivity.
This pot only provides an extremely fine adjustment of the tail lock system. These
changes will be difficult to detect until you become very familiar with the flight per-
formance of the G5000T after many flights.
