Receiver Diagram

Function

Installing the AR40210T Receiver

1. Mount the receiver using the four rubber mounting grommets on the side of the case, screwed into a solid mounting platform. The receiver may be mounted in any mounting orientation.

2. If using the optional Synapse sensor, mount it sensor square with the centerline of the airplane.

3. If using the optional Synapse sensor, Connect the cable between the sensor and receiver.
   IMPORTANT : For SAFE setups, install the Synapse sensor as close to the center of gravity of the aircraft as practical.

4. Connect the servos to their respective ports on the receiver.
   CAUTION : when using the Synapse and AS3X+, incorrect installation of the sensor could cause a crash. Always perform a control surface check and AS3X+ control surface response test before flying a new setup, or after any setup changes. We recommend using the gyro response test setting to make gyro direction more visible, see AS3X+ Reaction Test in this manual for more information.

DEFAULT CHANNEL ASSIGNMENTS

Default channel assignments will change with transmitter selections for wing, tail, flaps and more. Follow the channel assignments defined in your transmitter after going through configuration for your model.
For electric models using a Spektrum Avian ESC, the throttle port should always be the #1 servo port, for Smart telemetry to function. Throttle will function in other channels, but there will not be telemetry. To use a Avian ESC in Smart mode and change needs to be mande after binding. Enter Forward Programming, select Other Settings, select Frame Rate, and change the Output Channel 1 to SRXL2. For more information about using an ESC, see Powering the AR20410T from the Servo Rail later in this manual.
You may use up to 14 channels in 14 ch mode for primary flight controls. Or, use up to 12 channels for flight controls, and channels 13–20 as secondary functions, called XPLUS channels. Enable XPLUS mode in your transmitter under the frame rate menu to enable these channels. XPLUS channels should be used for axillary controls, not primary flight controls.
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.

Remote Receiver Installation

Remote receivers may be mounted with foam insulated double sided tape, adhesive backed hook and loop tape, or silicone glue.
One 4651T telemetry remote receiver is included, and is required for full range telemetry operation. It may be connected to any remote receiver port (A, B, L, R). At least two remote receivers are required for operation, and there must be a remote receiver connected in port A.

ANTENNA PLACEMENT
Spektrum Multilink technology gives you the protection of multiple remote receivers working together to deliver a robust control link, but your installation plays a critical role in the performance of the control link.
Remote receivers should be placed as far away from conductive materials on the aircraft as possible such as motors, batteries, fuel tanks, engines, mufflers, wiring and anything made of metal. Special consideration is needed for composite models with carbon fiber construction. Receiver antennas should never be placed in locations where they are enclosed or blocked by carbon fiber.
Any electronic component should be considered a possible source of RFI (Radio Frequency Interference) including BECs, electronic speed controllers, electronic ignition systems, and cameras. Locate the remote receivers as far from any sources of RFI as possible.
Antennas should be placed in different orientations and locations to maximize the effectiveness of multilink technology. There should always be one or more receiver antennas with an optimal path to the transmitter, regardless of the model’s orientation. Antennas should be oriented with one antenna vertical, and one antenna horizontal. If you have a system with three antennas we suggest installing two antennas vertical, one horizontal. If you have a system with four
antennas we suggest installing two antennas vertical, one horizontal parallel to the direction of flight and one horizontal perpendicular to the direction of flight.
Always try to maximize separation between the remote receivers to further improve control link performance.
The three included SPM9747 remote receivers have an antenna integrated into the circuit board, there is no external antenna.
The included SPM4651T telemetry remote receiver has coaxial style antennas.
The last 31mm at the end of the coaxial cable is the active antenna element and what needs the most consideration for placement on this remote receiver.
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.

Powering the AR20410T Receiver

DUAL POWERSAFE INPUT LEADS
The AR20410T is designed to be powered by two matching batteries, up to 3S Li- Po through the two IC3 input leads. The receiver does not regulate the voltage from the batteries, it will switch between power sources to maintain the highest voltage possible at all times. The AR20410T is designed to be powered from the IC3 power input leads by default, which is the recommended configuration to be able to take advantage of the built-in safety features.
PowerSafe safety features include the power button and fastboot functionality.
Do not connect a battery or an ESC with a BEC to the servo rails when using the PowerSafe system.

POWERING ON THE AR20410T WITH POWERSAFE

By default, the AR20410T may be powered on from the built-in button on the receiver case, or with an external power button connected to the switch port (Sw). Only use the included momentary button for remote switch functionality.
Power button (or remote switch) functionality:

1. Connect your fully charged (matched) batteries to the IC3 battery connectors.
2. Hold the button for the system to power on.
3. Tap, release, then press and hold to power off.
4. You may leave the batteries connected during a flying session.
5. For transportation and storage we recommend disconnecting your receiver batteries after powering the system off.

IMPORTANT : Do not disconnect the batteries from the receiver to power it off when using the PowerSafe system. If you pull power from the receiver without powering if off first, it will bypass the power button and normal initialization
steps because it is meant as a brownout recovery feature.

SLEEP AND WAKE FROM YOUR TRANSMITTER
Use the quick double tap feature on your transmitter to bring up the sleep screen. Once updated to the newest firmware, your transmitter will show options for the receiver as well. You cannot power the receiver on from the transmitter. Once powered on and connected, you have the option to power the receiver off or put it to sleep from the airware menu on your Spektrum transmitter. If the pair are put to sleep together, the transmitter will ask if you want to wake up the receiver when you wake up the transmitter. The receiver will display a slow blue flashing LED when in sleep mode.

POWERING THE AR20410T FROM THE SERVO RAIL
If you wish to use an ESC with a BEC (provides voltage to the servo rail from the flight battery), you must first power the receiver with a battery connected to an IC3 battery input lead. Power the receiver on with the button, bind and enter the forward programming menu > PowerSafe Telemetry > Power Source and change the selection from Battery Ports to Servo Rail. Exit Forward Programming and reboot the receiver to save the changes. If you are using this setting the power button will not function, and you cannot sleep the receiver from your transmitter. WIth this setting you can power the receiver on like any conventional receiver by connecting power to the servo rail.

Transmitter and Receiver Binding

The AR20410T receiver must be bound to your transmitter before it will operate.
Binding is the process of teaching the receiver the specific code of the transmitter so it will only connect to that specific transmitter.

1. Connect the SRXL2 remote receivers (SPM4651T, SPM9747) and any telemetry sensors to the main receiver.
2. Connect your batteries to the IC3 input connectors
3. Push and hold the power button on the receiver to power it on.
4. Press and release the bind button until the orange LEDs on the receiver and the remote receivers start to flash, indicating the receiver is in bind mode.
5. Put your transmitter in bind mode.
6. The bind process is complete when the orange LEDs remain solid. Once a bind is established, the bind data will be relayed throughout the system.

IMPORTANT : 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 difficult 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.
IMPORTANT : You may also put the system into bind mode by pressing a bind button on one of the remote receivers (the system won’t enter bind if it has been connected to a transmitter since being powered on).
IMPORTANT : Bind data is verified on every startup. Thanks to this feature, it is not necesary to re-bind the system if a remote receiver is replaced.

Telemetry

The AR20410T features full range telemetry and will provide receiver battery voltage, flight log data, and variometer 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. Many XBus telemetry devices have two XBus ports, and XBus telemetry sensors can be connected in a daisy chain in any order. The Spektrum Sky Remote ID module (SPMA9500) may be connected to the bind port, remote rx port (B,L,R), or #1 servo port.*
All telemetry connections with the system take place through the 4651T. If telemetry connection problems exist, investigate the placement of the 4651T antennas. It is also possible to use more than one 4651T telemetry remote receiver to improve the received telemetry performance on the ground.
See www.spektrumrc.com for more information about telemetry accessories.

• A Y-harness may be used with a Spektrum Avian Smart ESC on the #1 servo port. Do not use a Y-harness for a conventional servo or ESC.

Initial Setup

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

IMPORTANT : Do not use open mixes for primary flight control setup on the AR20410T when using a Synapse for AS3X+ and SAFE. If necessary, refer to aux output setup online to add stabilization to secondary functions.

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 AR20410T. 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 specific 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
(Available with Synapse sensor) 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 flies a gentle gliding turn, preventing a flyaway. 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, if equipped. 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.

Range Testing

Before each flying 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 flying 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 flight 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 significant amounts of conductive materials (e.g. turbine powered jets, scale aircraft with metalized finishes, aircraft with carbon fuselages, etc.), the following advanced range check will confirm 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 flying 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 necesary.

After one minute, advanced testing should yield:

H – 0 holds
F – Fewer than 10 frame losses
A, B, L, R – Fades will typically be fewer than 100. It’s important to compare the relative fades. If a particular receiver has a significantly 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 the 4651T telemetry remote receiver to investigate the performance of the telemetry link.

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

Fades
Represents the loss of one bit of information on one receiver. Fades are used to evaluate the performance of each individual remote receiver. If a fade value is showing higher than the others, inspect or reposition the remote receiver or it’s
antenna(s) to optimize the RF link.
Remote receiver fades in flight log telemetry report as “—” when they have no RF data. This can help identify remote receivers that aren’t bound, damage to the remote receiver wires, or connectors that are not fully seated.

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 flight. 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 flying again.
IMPORTANT : 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 AR20410T receiver.

Basic AS3X+ Setup (Synapse Sensor Required)

1. Make sure your airplane is set up for flying (reversing, travel, subtrims, etc).
   Run through the First Time setup in forward programming and assign a channel for adjusting the gain such as the rotary knob or slider.

2. Before flying, gyro response direction can be verified using the Gyro Response Test menu (Gyro Settings > System Setup > Utilities > Gyro Response Test).

3. Use the gain channel to adjust gain in flight and evaluate the gyro response.
   Gain should be tuned while flying near or at max speed.
   a. In most cases, the pilot will be able to find a gain value that offers improved performance without additional tuning of individual settings.
   b. Due to the addition of the new parameter Stop Lock Rate delaying gain return from centering the stick, the gain might end up too high without the pilot noticing. This is more likely to happen on a calm day because turbulence from wind will induce oscillations which will highlight when the gain is too high.
   i. The preferred method of addressing this is to temporarily increase Stop Lock Rate to 100% for all 3 axes. Then stick inputs can be used to evaluate the current gain. This will ensure having full or closer to full gain the moment the stick is released. Start with low gain and work up. If the model continuously oscillates/bounces more than once, then the AS3X+ gain is too high and needs to be reduced (One or two bounces are acceptable). Once the gain is set, the Stop Lock
   Rate can be reset back to defaults to remove any small oscillations.
   ii. Another method of testing the gain which is quicker but less effective, is to leave the Stop Lock Rate at defaults. Then, use short/quick stick inputs, returning quickly to center, to induce movement in the model.
   Due to these delays, short/quick inputs will reduce gain much less, and will allow the model to stop more with the gyro as opposed to naturally.

4. If any movement other than Roll starts experiencing oscillations as gain is increased, Pitch and Yaw can be reduced in Gyro Settings>AS3X+ Settings>AS3X+ Gain.

5. If the gain channel is all the way up and no oscillations can be induced in the model, the multiplier can be increased in Gyro Settings>AS3X+ Settings.
   Conversely. If the gain channel is barely increased and oscillations are observed, the gain multiplier should be decreased to provide a wider window of adjustment.
   Once the preferred flight performance is achieved, use the Capture gain settings feature (Gyro Settings > AS3X+ Settings > Capture Gyro Gains) This page will preview where your gain will be at once captured. Use this to lock
   the gains in this position. Once the Capture Gyro Gains selection has been used any adjustable gains selections in that flight mode will be defaulted back to fixed. The selected gyro gain switch is changed to inactive, and the model can be flown as normal. Or, you can move on to the Advanced Tuning for more refined options.

Gyro Response Direction Test (when using a Synapse)

This test ensures that the AS3X+ control system has the directions and any auxiliary control surface configurations set up 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. From the Forward Programming menu select Gyro Settings > System Setup > Utilities > Gyro Response Test.
   This test will set all gyro response to maximum gain to make it easy to see control direction response. Do not fly in the Gyro Response Test mode.

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 fly the aircraft.
   Rudder| Aircraft Movement| Control Surface Reaction
   ---|---|---
   |
   |
   Elevator| |
   |
   Aileron| |
   |

The Gyro Response Test is only a direction test, it does not test if you have gain applied in a given flight mode/configuration.

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 Synapse sensor orientation matches the selected diagram. The image of the airplane is from the top. If your access to the sensor is from the bottom, remember the images on the screen need to match the way the sensor sits in the model when it is upright.

AS3X+ Preflight Test (when using a Synapse)

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

1. Use the Gyro Response Test in the Forward Programming menu to verify the control surfaces are responding in the correct direction 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 and ensure the control surfaces respond, and verify you understand how the gains are applied in each flight mode/configuration.
