EN Specifications Type Dimensions (L × W × H) Antenna Length Channels Weight Band Voltage Range AR631 AS3X/SAFE Receiver with Telemetry 39mm x 24mm x 14mm 230mm 6 8g 2404 MHz – 2476 MHz 3.5–9.6V Bind Button Smart Port 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.
EN INSTALLING THE AR631 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.
EN 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 AR631. 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.
EN AR631 RECEIVER – BASIC AS3X SETUP To use AS3X technology with the Spektrum AR631 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 configured through the Forward Programming menu. a. Low throttle is required to enter Forward Programming, we recommend enabling throttle cut and verify it prevents motor operation.
EN 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 respose to aircraft movement. AS3X remains active until the battery is disconnected.
EN AR631 RECEIVER – SAFE SETUP Setting up SAFE® Technology on the AR631 Receiver takes place in Forward Programming. 1. Complete the AS3X setup and verify operation in flight. 2. Forward Programming Setup: To add SAFE flight stabilization the Flight Modes on the receiver need to be configured. a. 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.
EN c. If the airplane oscillates, immediately slow it down and reduce gain. Take note of which flight 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 flight mode within the Forward Programming menu after landing. d. Tune gain values for each axis within each flight mode.
EN 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. c. 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. d. Enable the Panic function if you want to be able to trigger Panic (bailout) from that flight mode. This setting only defines if Panic is accessible from the selected Flight Mode.
EN 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 flight mode selection.
EN (AS3X) System Setup Select Forward Programming -> Gyro Settings -> System Settings -> • Relearn Servo Settings can be accessed if any changes are made to the model configuration outside of Forward Programming. If any changes are made to servo reversing, travel, sub-trim, wing type or tail type, you can execute this function instead of restoring factory defaults and redoing the entire setup. • Orientation can be changed from this menu if the receiver mounting is changed.
EN OTHER SETTINGS (FORWARD PROGRAMMING) System Setup Select Forward Programming -> Other Settings -> • Select Failsafe -> Select each channel and assign it to Preset or Hold Last. When you select a different channel for Output, a new group of settings appears. Capture Failsafe Positions -> Hold the control sticks in the desired failsafe positions and select Apply. Channel selections must be individually set in Forward Programming to apply the preset positions or each channel will default to Hold Last.
EN Differences between Self Leveling/Angle Demand and AS3X modes This section is generally accurate but does not take into account flight speed, battery charge status, and other limiting factors.
EN 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 receiver B - Not available on AR631 L - Not available on AR631 R - Not available on AR631 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 the receiver (Each individual receiver on a MultiLink receiver).
EN 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.
EN 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 AR631 has a minimum operational voltage of 3.
EN Flight Modes in Transmitter - Manage rates, expo, voice/sound output, and other transmitter based configurations. 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.
EN TROUBLESHOOTING GUIDE AS3X Problem Possible Cause Damaged propeller or spinner Imbalanced propellereller Motor vibration Loose receiver Oscillation Loose aircraft controls Worn parts Irregular servo movement Gain too high Travel or Rates reduced causing reduced servo resolution Trim changes after initial setup 20 Inconsistent flight performance Changes to SubTrim after initial setup Incorrect response to the AS3X Control Direction Test Aircraft was not kept immobile for 5 seconds after battery c
EN TROUBLESHOOTING GUIDE Problem Aircraft will not respond to throttle but responds to other controls Possible Cause Solution Throttle not at idle and/or throttle trim too high Throttle servo travel is lower than 100% Reset controls with throttle stick and throttle trim at lowest setting Make sure throttle servo travel is 100% or greater (With battery disconnected from aircraft) Reverse throttle channel on transmitter Make sure motor is connected to the ESC Move powered transmitter a few feet from air
EN TROUBLESHOOTING GUIDE Problem Aircraft will not connect (after binding) to transmitter Possible Cause Solution Transmitter too near aircraft during connecting process Move powered transmitter a few feet from aircraft, disconnect and reconnect flight battery to aircraft Aircraft or transmitter is too close to large metal object, wireless source or another transmitter Move aircraft and transmitter to another location and attempt connecting again Bind plug left installed in bind port Aircraft bound
