Spektrum SPMAR20410TS AR20410T 20-Channel PowerSafe Receiver with Synapse AS3X and SAFE Stabilization Module
The Spektrum™ AR20410T PowerSafe™ receiver is a feature-packed 20-channel receiver with full-range telemetry. Spektrum PowerSafe receivers are designed for models using numerous servos and accessories that draw excess current, such as those found on giant-scale airplanes and jet models. Now, with innovative features like fast boot recovery, regenerative servo support, remote sleep mode, and the all-new Synapse AS3X+ module.
The revolutionary Spektrum Synapse™ Flight Stabilization Module is vastly improved over its predecessor, the AS3000. Equipped with the all-new AS3X+ stabilization algorithm, the Synapse has been rigorously tested by experts throughout the hobby and has been put to the ultimate test. Spektrum has taken years of customer feedback on the AS3000 and purpose-built the Synapse with turbine aircraft and giant scale in mind. Its lightweight design and innovative features make it the ideal choice for pilots needing the best in-flight stabilization in today’s world of complex models.
Historically, pilots had to reduce the performance of stabilization systems by lowering gains to fine tune to their personal feel. Now, our new parameters of stop lock and release rate allow you to customize the feel of the gyro system while providing optimal stabilization performance.
With the Synapse we are introducing the ability to adjust AS3X+ and SAFE settings with 10 customizable channels for all flight controls. This allows pilots to precision tune their aircraft while in flight. Additionally, we’ve also added support for configuring auxiliary outputs, which means you can now stabilize outputs tied to mixes or other outputs that are separate from your traditional wing types. For example, if you had flaps that were set up to become ailerons using a mix and a flip of a switch, you can now configure those surfaces to have stabilization as well.
We've added support for multiple gyro systems within a single device. This provides the equivalent functionality of running multiple gyro systems or flight controllers within one system, allowing you to add stabilization to unique outputs such as thrust vectoring or canards without the need of buying an additional gyro. Changes were made to the gyro filtering for improved response time. This allowed us to essentially double the effectiveness of our gains in some cases. Ultimately, this helps to further increase aircraft stability in rough air.
Lastly, significant improvements were made to how heading hold mode operates. Now, transitions between user inputs and heading hold are more seamless which provides a more natural feel in flight. With the Synapse we've isolated the sensor in Synapse to combat against acoustic interference that might be seen in some turbine applications. All of that is wrapped in a beautiful aluminum case with three vibration-damped mounting points.
Paired with the new Spektrum AR20410T PowerSafe receiver, it is an incredible combo of advanced stabilization and cutting-edge electronics.

Spektrum AR20400T 20 Channel PowerSafe Telemetry Receiver
The Spektrum™ AR20400T PowerSafe™ receiver is a feature-packed 20 channel receiver with integrated full-range telemetry. Spektrum PowerSafe receivers are designed for models using numerous servos and accessories that draw excess current such as those found on giant-scale airplanes and jet models. They feature a robust power bus designed to manage high-current loads, as well as dual 13AWG battery input leads with IC3™ connectors for use with larger battery packs. This makes it possible to support high-current systems straight through the receiver without the need for a separate power distribution system.
If you have a DSMX®/DSM2® transmitter capable of 11ms frame rates, the AR20400T will deliver lightning-fast input-to-output response that is perfect for high-performance applications such as aggressive 3D , IMAC, and Turbine airplanes. Each receiver includes 4 SRXL2 remote receivers that take full advantage of Spektrum MultiLink™ technology. This patented technology eliminates the reflected signal fading and antenna blind spots that can affect all 2.4GHz systems, helping insure a solid connection between you and your aircraft. As an added measure of safety, the Spektrum designed the AR20400T receiver with a proprietary soft switch. Allowing servo current to be routed around the switch, so, should the switch fail for any reason, power to the system will not be interrupted.
A ground-breaking feature on the AR20400T PowerSafe Receiver is the built-in receiver battery energy sensors. Giving pilots added awareness of the load and mAh used by the servos, retracts, lights, etc. used by each battery.
Each come with built-in connection ports for RPM, Flight Pack Voltage and Temperature sensors as well as an X-Bus port for additional telemetry options.
Patented PowerSafe™ Redundancy System
The Spektrum™ AR20400T is the ultimate solution for powering high-current draw radio systems. In aircraft with multiple high-current draw servos (e.g. giant-scale aircraft, jets, etc.), PowerSafe redundancy expertly manages power between both connected receiver batteries with true dual battery redundancy. Each battery is isolated and if one fails/shorts the other seamlessly takes over.
Innovative Battery Capacity Monitor
The PowerSafe receivers feature dual battery capacity monitoring through telemetry when used with Spektrum AirWare™ transmitters. Activate the Auto Config function on the telemetry page in your transmitter to display the capacity consumed by the receiver. The capacity used is stored flight to flight and adds until reset. The capacity can be automatically reset when the battery is charged, allowing easy battery capacity monitoring.
Integrated "Black Box" Telemetry Logging
When a micro SD card is inserted into the receiver, during operation, flight information will be logged onto a file on the card including flight log data, battery status and other telemetry data stored over time. If not deleted, older data logs recorded will be deleted, keeping the most recent logs. This can be a handy tool to review flight data over time which can be helpful for diagnosis of performance.
Forward Programming
You can configure the AR20400T receiver wirelessly, directly from any compatible Spektrum™ transmitter, through the Forward Programming menu. No separate computer or mobile device is needed for setup and adjustments.
