Smart Throttle

With Smart Technology the normal servo connector delivers the throttle signal

to the ESC, plus the ESC can send telemetry data like voltage and current

back to the receiver. The AR8360T receiver throttle port (Channel 1 port only)

will automatically detect when a Smart compatible ESC is connected. ESCs

with Smart and IC series connectors can also pass along battery data from

compatible Spektrum Smart batteries. Spektrum Avian™ ESCs are compatible

with the AR8360T receiver for Smart Technology features.

For Smart to function you must have a Smart ESC paired with a Smart

telemetry receiver, and a Spektrum DSMX transmitter with telemetry. An update

for your transmitter may be required for Smart features. See www.spektrumrc.

com to register and update your transmitter.

If a standard ESC or servo is plugged into the throttle port on the AR8360T

receiver, the throttle port will operate normally (PWM signal) like any

conventional RC system.

Installing the AR8360T Receiver

1. Mount the receiver using double-sided servo tape. The receiver may be

mounted upright, upside down or on its side, but it should be square with

the fuselage in its mounting position. The receiver cannot be mounted at

an odd angle.

TIP: For SAFE setups, install the receiver as close to the center of gravity of

the aircraft as practical.

2. Connect the servos to their respective ports on the receiver using the chart

below.

CAUTION: Incorrect installation of the receiver could cause a

crash. Always perform a control surface check and AS3X control

surface response test before ying a new setup, or after any setup changes.

Telemetry

The AR8360T features full range telemetry and will provide receiver battery

voltage, ight log data, vertical speed, and altitude data without any additional

sensors. Additional telemetry devices such as voltage sensors can be

connected to the volt port, and XBus telemetry sensors can be connected

through the XBus connector. Every XBus telemetry device has two XBus ports,

and XBus telemetry sensors can be connected in a daisy chain in any order.

The AR8360T is not compatible with the Spektrum Temperature Sensor (SPMA9571)

See www.spektrumrc.com for more information about telemetry accessories

IMPORTANT:

When using Y-harness or servo extensions with Spektrum

equipment, do not use reversing harnesses. Using reversing Y-harnesses or

servo extensions may cause servos to operate erratically or not function at all.

EN

6

Programming the AR8360T receiver requires a Spektrum™ DSM2®/DSMX®

compatible transmitter with Forward Programming.

Transmitter and Receiver Binding

Binding

The AR8360T receiver must be bound to your transmitter before it will operate.

Binding is the process of teaching the receiver the specic code of the transmitter

so it will only connect to that specic transmitter.

1. Connect the optional SRXL2 remote receiver (SPM9747 or SPM4651T) if

desired and any telemetry sensors to the main receiver.

2. Push and hold the bind button on the receiver while turning the receiver on.

Release the bind button once

the orange LED starts

to ash continuously,

indicating the receiver

is in bind mode.

TIP: It is still possible to

use a bind plug in the

bind port if desired. This can

come in handy if the receiver needs

to be mounted in a location that is difcult

to access, in which case a servo extension may

be used for binding. If using a bind plug, remove after

binding to prevent the system from entering bind mode

the next time the power is turned on.

3. Put your transmitter in bind mode.

4. The bind process is complete when the orange LED on the receiver is solid.

ANTENNA INSTALLATION

The AR8360T receiver has coaxial style

antennas. We recommend installing the

antennas oriented 90º from each other and as

far as possible from metal, batteries, carbon

ber or fuel tanks to maximize signal reception

performance.

NOTICE: Do not cut, kink, or modify the antennas. Damage to the coaxial

portion of an antenna will reduce the performance of the antenna.

Shortening or cutting off the 31mm tip will reduce the range.

Active portion

EN

7

Failsafe

In the unlikely event the radio link is lost during use, the receiver will enable

the selected failsafe mode. Smart Safe + Hold Last is the default failsafe mode

on the AR8360T. Preset Failsafe and SAFE Failsafe modes are only available

through Forward Programming.

SmartSafe + Hold Last

If loss of signal occurs, SmartSafe™ technology moves the throttle channel to

the failsafe position (low throttle) set during binding. All other channels will hold

their last position. When the receiver detects the signal from the transmitter,

normal aircraft operation resumes.

Preset Failsafe

With preset failsafe, you can set the specic control surface positions you

want to use if the signal is lost. When the receiver detects the signal from the

transmitter, normal aircraft operation resumes.

Preset failsafe mode is only available through Forward Programming.

SAFE Failsafe

SAFE Failsafe mode will work to automatically level your aircraft if the signal

is lost. In the forward programming menu you can select the bank and pitch

angles the aircraft will attempt to maintain during failsafe. We recommend

setting bank and pitch angles so the aircraft ies a gentle gliding turn,

preventing a yaway. You must complete First Time SAFE Setup before this

option is available.

SAFE Failsafe mode is only available through Forward Programming.

Testing Failsafe

Secure the aircraft on the ground and remove the propeller. Test Failsafe

settings by turning the transmitter RF output off and noting how the receiver

drives the control surfaces.

Receiver Power Only

• The servo ports will not have a control signal if the receiver is turned on

when no transmitter signal is present.

• All channels have no output until the receiver has linked to the transmitter.

Initial Setup

1. Verify your transmitter is updated to the latest Spektrum AirWare™ software

to take advantage of Forward Programming. See your transmitter manual

for updating instructions.

2. Install

the receiver in your airplane.

3. Bind the receiver to your transmitter.

4. Complete the airplane setup on your transmitter including wing type, tail type, channel

assignments, mixing, sub trim and travel the same as you would for any other aircraft

without AS3X. Verify the center of gravity is correct and test y your aircraft.

IMPORTANT: Do not use open mixes for ight control surfaces when setting

up a model with the AR8360T for AS3X and SAFE. Only use wing and tail type

options to congure ight controls, refer to your transmitter manual for more

information about wing and tail type features.

AR8360T Receiver- Basic AS3X Setup

To use AS3X technology with the Spektrum AR8360T Receiver, the receiver needs

to be set up with a compatible Spektrum transmitter.

1. Verify the basic setup and trim is accurate before attempting AS3X setup.

2. Forward Programming Setup: The receiver is directly congured through

the Forward Programming menu.

1. Low throttle is required to enter Forward Programming, we recommend

enabling throttle cut and verify it prevents motor operation. The

transmitter will not allow you to enter the Forward Programming menu

unless throttle is low or throttle cut is activated.

2. In your transmitter’s menu, select:

Forward Programming -> Gyro Settings -> First Time Setup

The transmitter will prompt you for all setup steps.

IMPORTANT: Before proceeding with setup, read every information screen that

appears on your transmitter

Select NEXT at the bottom of each page to continue.

3. Follow the on-screen prompts to set the orientation. Select

Continue

to

complete the two-step auto detection process, or select

Set Orientation Manually

. Verify the orientation is correct.

4. You can a

ssign any open channel to a switch (trimmer, knob, etc) for gain,

and assign that channel for gain. You can assign a switch to a channel

from

the Forward Programming menu so you don’t have to exit the

menu.

We recommend using a trim

mer, knob, or slider for gain, which will

enable you to change the gain value on the y.

When the setup screens are complete select Apply.

3. AS3X Tuning Basics:

1. Perform a control surface direction test, and AS3X reaction test.

2. Test y the airplane to verify the conguration. In-ight trim changes do

not require any further updates. If the airplane needs sub-trim, travel or

other setup changes in the transmitter programming, select

Forward Programming -> Gyro Settings -> System Settings ->

Relearn Servo Settings after making the needed changes.

3. Oscillation occurs because the system is overshooting the correction, and

will usually occur at higher speeds. If the airplane oscillates, immediately

reduce speed and lower the gain value. Take note of which axis the

aircraft oscillates around; you can increase or decrease the base gain

values of each axis separately within the Forward Programming menu

after landing.

4. Increase the gain values until you nd oscillation, and then reduce the

gain to the highest setting that will not cause oscillation at any speed.

This value will help the airplane track accurately and y smoothly in

wind and turbulence.

EN

9

AS3X Reaction Test

This test ensures that the AS3X control system is functioning properly.

1. Assemble the aircraft, bind your transmitter to the receiver, and complete the

AS3X First Time Setup in the Forward Programming menu before performing

this test.

2. Raise the throttle above 25% to activate AS3X, then lower the throttle. Once

the AS3X system is active, control surfaces move in response to aircraft

movement. AS3X remains active until the battery is disconnected.

CAUTION: Activate throttle cut to prevent motor operation during

this test.

3. Move the aircraft as shown and ensure the control surfaces move in the

direction indicated in the graphic. If the control surfaces do not respond as

shown, do not y the aircraft.

Aileron

4. If the control surfaces do not respond as shown, review the receiver

mounting orientation.

1. In your transmitter’s menu select

Forward Programming -> Gyro Settings -> System Setup -> Orientation

2. Verify the receiver orientation matches the selected diagram. The image

of the airplane is from the top. If your access to the receiver is from the

bottom, remember the images on the screen need to match the way the

receiver sits in the model when it is upright.

AR8360T Receiver- SAFE Setup

Setting up SAFE Technology on the AR8360T Receiver takes place in Forward

Programming.

1. Complete the AS3X setup and verify operation in ight.

2. Forward Programming Setup: To add SAFE ight stabilization the Flight

Modes on the receiver need to be congured.

1. In your transmitter’s menu select

Forward Programming

->

Gyro Settings

->

First Time SAFE Setup

IMPORTANT: Before proceeding with setup, read every information screen that

will appear on your transmitter screen.

Select NEXT at the bottom of each page to continue.

2. Select FM Channel-> Select the channel and switch you want to use

for Flight Mode selection. You can select any channel that is not a control

surface, throttle or gain. Select Continue.

3. Position the model in a level ight attitude, then select

Level Model and Capture Attitude to teach the receiver the baseline

setting. For taildragger aircraft be sure to raise the tail so the fuselage is level.

4. Assign SAFE to the desired ight modes. You can enable or disable SAFE

for each ight mode. Take into account your ight mode switch position,

and set the SAFE Mode as desired for the rst switch position.

• Envelope (Intermediate) mode does not use self leveling. The aircraft

will y like a normal AS3X setup, but it will be bank and pitch angle limited.

• Self Leveling/Angle Demand will make the airplane return to level

ight when the control stick is centered.

5. Set the Angle Limits as desired for the rst switch position. These

values determine how far the aircraft will be allowed to pitch or bank.

6. Move the Flight Mode switch to the other positions, a setup screen for

SAFE Mode and Angle Limits will appear for each mode. Set the SAFE

Mode and Angle Limits as desired for every mode.

7. After all the Flight Modes are congured as desired for SAFE Modes and Angle

Limits, press Apply.

8. Test y the airplane to verify the conguration.

3. Tuning SAFE Basics:

1. Perform a control surface direction test, and AS3X reaction test. You can verify

which modes have SAFE enabled by performing the AS3X test, starting at the

level ight attitude.

• AS3X reaction will move the control surfaces in response to rotational

movement, and then return to center when the rotation stops.

• SAFE (Self Leveling) will

cause the control surfaces to stay deected as long

as the aircraft is banked or pitched.

2. Test y the airplane to verify the conguration in every ight mode.

3. If the airplane oscillates, immediately slow it down and reduce gain. Take note

of which ight mode you are in and which axis the aircraft oscillates around. You

can increase or decrease the base gain values of each axis separately for each

ight mode within the Forward Programming menu after landing.

4. Tune gain values for each axis within each ight mode.

EN

11

Advanced Tuning

Basic gain tuning can be as simple as using a slider, but to ne tune the AS3X

system there are many setup and tuning options.

AS3X Gain tuning options

1. In your transmitter’s menu select

Forward Programming -> Gyro Settings -> AS3X Settings

• AS3X Gains can be changed for each axis, you can increase the gain values

for roll, pitch and yaw separately to maximize the performance without

oscillation. We recommend making small changes on one axis at a time.

• Priority tells the receiver how much to reduce gain when you move the

control stick away from center. If the Priority is set high (200) the receiver

will lower gain to zero with any movement on the control stick. Low

priority values will dampen more throughout the control input range. The

default value of 160 provides a well balanced feel for most pilots.

• If your aircraft is over or under sensitive to the range of gain available,

adjust the Gain Sensitivity. Agile aircraft with extreme control surface

deections or high speed aircraft should use 1X. Moderate sport airplanes

should use 2X. Slow and inherently stable aircraft with mild performance

should use 4X.

2. Test y your airplane to verify the conguration, land, and make adjustments

as necessary.

Flight Mode tuning options within Forward Programming

(in the receiver)

1. Flight Modes in Forward Programming are set up in the receiver and are

separate from Flight Modes set up outside of Forward Programming. You can set

base gain values, and enable or inhibit AS3X and SAFE for each Flight Mode.

Select Forward Programming -> Gyro Settings -> F-Mode Setup

1. Select FM Channel, assign a channel and switch to use for Flight Modes.

Select any channel that is not a control surface, throttle or gain.

TIP: If you have completed the First Time SAFE Setup, your Flight Modes will

already be assigned to a switch.

2. Each Flight Mode within Forward Programming can have AS3X and SAFE

enabled or disabled. For all ight modes with SAFE enabled, AS3X should

be enabled as well. Take into account your ight mode switch position,

then set the AS3X and SAFE Modes as desired for that switch position.

TIP: If you have not completed the First Time SAFE Setup, you will not see any

SAFE related options on the F-Mode Setup Screens.

3. SAFE Flight Modes have an AS3X gain and a SAFE gain for pitch and roll axis.

Both of these values are used for SAFE and may be tuned independently.

4. Enable the Panic function if you want to be able to trigger Panic (bailout)

from that ight mode. This setting only denes if Panic is accessible from

the selected Flight Mode. Complete Panic Mode Setup under

Forward Programming -> System Setup -> SAFE/Panic Mode Setup

5. For Modes with SAFE self leveling/angle demand, you can choose to

enable High Thr to Pitch and/or Low Thr to Pitch or not.

6. Move the Flight Mode switch to the other positions; a setup screen will

appear for each mode. If Panic is not enabled on a selected mode, you

will not be able to trigger Panic when you are in that Flight Mode. Set the

SAFE Mode and Angle Limits as desired for every mode.

EN

12

2. When you add Flight Modes within Forward Programming, additional tuning

options are added in the AS3X Setting menu. Be sure to change through all

the ight modes with your assigned switch and verify values for each feature

for every ight mode.

Select Forward Programming -> Gyro Settings -> AS3X Settings

• AS3X Gains can be adjusted for each axis and each mode. Change the

ight mode switch position when this option is selected and a separate

screen will appear for AS3X gains on each ight mode. Adjust the values

in each mode and each axis as needed.

• Priority screens will also appear for each ight mode, adjust the values

as desired.

• Heading screens will appear for each ight mode and are defaulted to

zero. You can increase this value to make the aircraft hold its attitude

when control input is neutral. Heading gain on the yaw axis is generally

not recommended because it will require the pilot to steer the aircraft

through any heading changes.

• Fixed/Adjustable Gain will let you use xed values or adjust the gain

from the assigned Gain channel. Each Flight Mode has a separate

screen with a separate set of values so each axis can be set to Fixed or

Adjustable in each Flight Mode.

• Capture Gyro Gains lets you easily set your base gain setting. If you are

using a slider, knob or trimmer to adjust gain when test ying, you can set

the value you arrive at as the base gain setting in the ight modes using

this function. Select this option from the AS3X Settings menu, verify ight

mode, verify the slider, knob or trimmer is in the desired position, and

select Capture Gyro Gains to set the values for the chosen Flight Mode.

Adding Flight Modes outside of Forward Programming

(in the transmitter)

Flight Modes outside of forward programming are set up in the main transmitter

menu and are separate from Flight Modes set up within forward programming.

Flight Modes in the transmitter tie together transmitter-based features like dual

rates and expo, selected channels and positions, trim, and voice/sound features.

1. Select Model Setup -> Flight Mode Setup

Assign a switch for the ight mode selection. See your transmitter manual for

more information about setting up Flight Modes on your transmitter.

2. Select Model Setup -> Channel Assign

Link the functions by assigning the Flight Mode channel. Select the same

Flight Mode channel you picked within forward programming, set the switch

to Flight Mode.

3. Select Model Setup -> Digital Switch Setup

Match the Flight Mode functions. Select Flight Mode in the switch selection,

a set of values appears for each ight mode.

Set Flight Mode 1 to 100%, Flight Mode 2 to 0%, and Flight Mode 3 to -100%.

4. Select Forward Programming -> Gyro Settings -> F-Mode Setup

Verify the ight modes change as expected when moving the Flight Mode

Switch.

5. (Only applies to transmitter with trimmer switches, DX9 and higher)

If you wish to be able to run a trimmer for gain independent for each ight

mode, Select Model Setup -> Trim Setup

Select F-Mode for the trimmer that is assigned to gain.

The

First Time SAFE Setup

should be sufcient to y your airplane, but to ne

tune the SAFE system there are many setup and tuning options.

Select Forward Programming -> Gyro Settings -> SAFE Settings ->

• SAFE Gains can be ne tuned for each axis within each Flight Mode.

• Angle Limits can be changed for each ight mode

• Fixed/ Adjustable Gain operates the same as this feature in AS3X, but

applies to SAFE gain. You can assign a separate SAFE gain channel for roll

and pitch if you have enough free channels. Use a different gain channel for

SAFE gain than what you have assigned for AS3X. It is possible to have up

to ve different channels assigned for ne tuning gain. AS3X roll, pitch and

yaw, and SAFE roll and pitch. If you are limited by channels, make your gain

changes within Forward Programming.

• Capture Gyro Gains operates the same as this feature in AS3X, but applies

to SAFE operation

(AS3X) System Setup

Select Forward Programming -> Gyro Settings -> System Settings ->

• Relearn Servo Settings can be accessed if any changes are made to the

model conguration outside of Forward Programming. If any changes are

entire setup.

• Orientation can be changed from this menu if the receiver mounting is changed.

• Gain Channel enables you to change the channel you are using to manage gain.

• SAFE/Panic Mode Setup

1. Panic

Select a channel to trigger Panic mode. Chose any channel that is not

used for a control surface, throttle, ight modes, or gain. We recommend

assigning the momentary I button for Panic.

Delay will cause a two second delay when exiting panic mode

Panic Flight Mode selects a Flight Mode to pull the gain values from for

Panic operation; select a Flight Mode that is setup with SAFE

Roll and Pitch values on this page represent angle limits while in Panic mode.

2. Throttle To Pitch

Low Thr to Pitch Threshold determines the trigger point below which

the airplane will descend nose down at the chosen angle.

High Thr to Pitch Threshold determines the trigger point above which

the airplane climbs at the chosen angle.

3. Attitude Trim allows you to redo the Capture Level Flight Attitude, and/or

manually ne tune the values based on ight testing.

4. SAFE Failsafe Flight Mode allows you to select a ight mode (with

SAFE congured) to act as a failsafe mode. Making this selection enables

SAFE Failsafe.

SAFE (Self Leveling) Flying Tips

When ying in SAFE Self Leveling/Angle Demand mode, the aircraft will return

to level ight any time the aileron and elevator controls are at neutral. Applying

aileron or elevator control will cause the airplane to bank, climb or dive. The

amount the stick is moved will determine the attitude the airplane ies. Holding

full control will push the aircraft to the pre-determined bank and roll limits, but

it will not go past those angles.

When ying with Self Leveling/Angle Demand, it is normal to hold the control

stick deected with moderate to full aileron input when ying through a turn. To

y smoothly with Self Leveling/Angle Demand, avoid making frequent control

changes and don’t attempt to correct for minor deviations. Holding deliberate

control inputs will command the aircraft to y at a specic angle, and the model

will make all corrections to maintain that ight attitude.

When ying with Self Leveling/Angle Demand, you have the option to enable

throttle to pitch angle demand. Throttle to pitch will make throttle dictate climb

angle. Full throttle will cause the aircraft to pitch up and climb slightly. Mid

throttle will keep the airplane ying level. Low throttle will cause the airplane to

descend slightly nose-down.

Return the elevator and aileron controls to neutral before switching from Self

Leveling/Angle Demand mode to AS3X mode. If you do not neutralize controls when

switching into AS3X mode, the control inputs used for Self Leveling/Angle Demand

mode will be excessive for AS3X mode and the aircraft will react immediately.

EN

15

Channel Limitations

The AR8360T can use up to seven extra channels for AS3X and SAFE functions;

one for Flight Mode selection, one for Panic Mode, and up to ve for Gain. You

may use any channel up to 20 that is not a control surface or throttle for these

functions, and you do not need to use channels 5 and 6, keeping those channels

and ports on the receiver open for normal servo operation. However, you may run

into channel limitations depending on the number of channels on your transmitter

and the number of channels you are using on the receiver.

TIP: If you are experiencing limitations because of channel count, here are a

few options;

• You can operate the AR8360T without a channel assigned to Flight Mode, but

you will only have access to AS3X options, not SAFE.

• You can set up one self-leveling mode to serve as Panic Mode so you don’t

need to dedicate a separate channel for Panic Mode.

• You can operate the AR8360T without a gain channel assigned, and just use

xed gain values throughout the conguration. To do this, rst assign ight

mode to a channel, then change all gain values to xed for ight mode 1, then

you can unassign the ight mode channel and it will remain in xed.

Flight Log

Flight Log data can help you optimize the control link for your aircraft. Flight

Log data is displayed on telemetry capable Spektrum transmitters.

Using the Flight Log

A - Fades on main receiver B - Fades on remote receiver

L - Not available on AR8360T R - Not available on AR8360T

F - Frame losses H - Holds

Fades

Represents the loss of one bit of information on one receiver. Fades are used to

evaluate the performance of each individual receiver. If a fade value is showing

higher than the others, inspect or reposition the antenna to optimize the RF link.

Frame Loss

A frame loss occurs when one complete data packet is missed. A single frame

loss does not represent a loss of control, but frame losses should be monitored.

In the air it's normal to experience as many as 100 frame losses per minute

of ight. On the ground the number of frame losses will be higher because the

signal is hampered by the dirt and moisture.

Hold

A hold occurs when 45 consecutive frame losses occur. This takes about one

second, and in this event the receiver moves the channel outputs to the failsafe

settings. If a hold ever occurs, it’s important to re-evaluate the system and

check every component. If your system displays a hold, diagnose the cause and

resolve the issue before ying again.

It is normal to see a hold logged if you power OFF your transmitter and back ON.

IMPORTANT: The Spektrum Flight Log (SPM9540) is not compatible with

the AR8360T receiver.

Range Testing

Before each ying session, and especially with a new model, it’s important to

perform a range check. All Spektrum aircraft transmitters incorporate a range

testing system, which reduces the output power to allow a range check.

1. With the model resting on the ground, stand approximately 100 feet (30

meters) away from the model.

2. Face the model with the transmitter in your normal ying position and put

your transmitter into range test mode.

3. You should have total control of the model in range test mode at 100 feet.

4. If you have control issues, review the ight log data to help reposition your

antenna(s), and repeat the range test.

5. If control issues persist, call Horizon Product Support for further assistance.

Advanced Range Testing

The standard range testing procedure is recommended for most sport aircraft.

For sophisticated aircraft that contain signicant amounts of conductive

materials (e.g. turbine powered jets, scale aircraft with metalized nishes,

aircraft with carbon fuselages, etc.), the following advanced range check will

conrm that all receivers in the system are operating optimally as installed.

This advanced range check allows the RF performance of each receiver to

be evaluated independently. A telemetry-equipped Spektrum Transmitter is

required for the advanced range test.

1. Stand approximately 100 feet away from the model.

2. Face the model with the transmitter in your normal ying position and put

your transmitter into range test mode.

3. Have a helper position the model in various orientations (nose up, nose

down, nose toward the transmitter, nose away from the transmitter, etc.).

4. Observe the telemetry on your transmitter. Note any orientations that cause

higher fades or frame loss values. Perform this step for at least one minute.

5. Reposition any remote receivers showing higher fades as necessary.

6. Retest to verify satisfactory results.

7. Repeat as necessary.

After one minute, advanced testing should yield:

H - 0 holds

F - Fewer than 10 frame losses

A, B - Fades will typically be fewer than 100. It’s important to compare the rela-

tive fades. If a particular receiver has a signicantly higher number of fades (2 to

3X) then the test should be redone. If the same results occur, move the offending

receiver to a different location.

TIP: Use the fade values for A to investigate the performance of the telemetry link.

Glossary

AS3X- Stabilization technology that dampens wind and turbulence. Designed to

support advanced iers, AS3X does not include self-leveling technology.

SAFE Envelope- (Intermediate Mode) Stabilization technology that uses AS3X

to deliver normal ight performance, but with limited bank and pitch angles to

prevent the airplane from getting into extreme attitudes.

SAFE Self Level/Angle Demand- Stabilization technology that will make the

airplane return to level ight when the control stick is centered.

Panic Mode- Sometimes called a bailout mode, Panic is a SAFE stabilization

mode that can return an airplane to level ight from any attitude. It is usually

assigned to a momentary button.

Flight Modes in Receiver- Determine what stabilization modes the aircraft

operates in. All the associated stabilization features to tune the ight stabilization

can be adjusted per Flight Mode in the receiver (Base Gain, Priority, Heading, etc).

Flight Modes in Transmitter- Manage rates, expo, voice/sound output, and

other transmitter based congurations.

Receiver Power System Requirements

Some of the power system components that affect the power supply to the

receiver include:

• Receiver battery pack (number of cells, capacity, cell type, state of charge).

• The ESC’s capability to deliver adequate voltage to the receiver when the

servos demand high current

• The switch harness, battery leads, servo leads, regulators etc.

The AR8360T has a minimum operational voltage of 3.5 volts; it is highly

recommended the power system be tested per the guidelines below.

Recommended Power System Test Guidelines

We recommend performing the following tests on any new setup to verify

power system performance:

1. View the receiver voltage during this test on your transmitter’s telemetry screen

2. Load the control surfaces (apply pressure with your hand) while monitoring

the voltage at the receiver.

3. The voltage should remain above 4.8 volts even when all servos are loaded.

How QuickConnect™ Technology Works

• When the receiver voltage drops below 3.5 volts, the system ceases to operate.

• When power is restored, the receiver immediately attempts to reconnect.

• If the transmitter was left on, the system reconnects typically in about

4/100 of a second.

QuickConnect is designed to allow you to y safely through most short duration

power interruptions, however, the root cause of these interruptions must be

corrected before the next ight to prevent a crash.

NOTICE: If a brownout occurs in ight it is vital that the cause of the

brownout be determined and corrected.

Heading- An optional feature of AS3X, heading will make the airplane try to hold

its attitude when the control is relaxed. This is not a self-leveling feature, it only

makes the aircraft track accurately.

Gain- Tells the stabilization system the level of damping it should provide.

SRXL2- A Bi-Directional data communication protocol that enables digital devices

to communicate over a single signal wire.

Forward Programming- Programming directly on the receiver from the

transmitter. The receiver has all screens, menus and settings in its internal

memory. The receiver is using the telemetry link to the transmitter for the

interface, the screen and buttons.

Throttle Cut- Disables throttle function

Oscillation- Sometimes called a wag, this is a back and forth movement similar

to a vibration that may appear like a wobble. It may occur around any axis, roll,

pitch or yaw. It is most likely to occur on one axis, not all three.

Overshoot- When the stability system makes corrections it is a balancing act,

if the response is too strong the system will go past where it should stop, this is

called an overshoot.

Angle Limits- Only available in SAFE modes, these values dene the limits for

the bank and pitch angles.

High Thr to Pitch- This setting denes the angle the airplane will climb at when

the throttle is raised above half. This is only available in Self Leveling modes.

Low Thr to Pitch- This setting denes the angle the airplane will descend at when

the throttle is lowered below half. This is only available in Self Leveling modes.

Brownout- If the receiver power supply drops below 3.5volts, the receiver will

not have sufcient power for operation and the resulting loss of control is call a

brownout. A brownout results from an inadequate power supply to the receiver, it

is a failure outside of the receiver.
