Key Features
- Full-Range Telemetry System — The AR8020T delivers comprehensive real-time telemetry data directly to your Spektrum DSMX transmitter, giving you instant access to critical flight information including current, voltage, temperature, and RPM without the expense of purchasing additional sensor modules or complicated external hardware.
- Integrated Barometer Technology — Built directly into the receiver chassis is a precision barometric pressure sensor that automatically provides altitude and variometer (vertical speed) telemetry data, eliminating the need for separate purchased sensor modules whilst maintaining the compact footprint that makes this receiver so versatile for various aircraft sizes.
- Dual External Antennas — Two external antenna ports ensure you receive secure RF coverage from all angles of your aircraft, providing comprehensive signal reception regardless of your aircraft's orientation during flight, which is essential for reliable control at distance.
- Bind Button Integration — The convenient integrated bind button allows for simple, plug-free binding with your Spektrum transmitter, making the initial setup process faster and eliminating one more component to lose or misplace in your field box.
- Smart ESC Compatibility — The throttle port is Smart ESC compatible right out of the box, allowing immediate integration with Spektrum Smart ESC units for seamless one-wire telemetry data transmission without requiring additional modules, links, or complex wiring configurations.
- Forward Programming Capability — This advanced feature allows you to configure individual failsafe parameters for each channel directly through your Spektrum transmitter, giving you precise control over exactly how your aircraft behaves in loss-of-signal scenarios.
- SRXL2 Remote Receiver Support — The dedicated SRXL2 port allows connection of an optional SRXL2 Remote Receiver (sold separately), providing additional RF path redundancy that enhances signal reliability and security during flight operations.
- SmartSafe and Hold Last Failsafe Options — The receiver offers both SmartSafe technology and Hold Last failsafe modes, with preset failsafe types configurable through forward programming, giving you flexibility to choose the failsafe behaviour that best suits your flying style and aircraft type.
- XBUS and Temperature Ports — Additional connectivity options via XBUS and temperature sensor ports allow integration of supplementary telemetry sensors available separately, enabling you to customise your telemetry setup precisely to your requirements.
- Compact Aerospace Design — The receiver's ultra-compact dimensions (1.92 inches long, 1.18 inches wide, 0.59 inches tall) and lightweight construction at just 0.56 ounces make it suitable for installation in parkflyer size aircraft, sport class models, and even giant scale RC planes where space is at a premium.
- Universal Spektrum Compatibility — This receiver works seamlessly with all Spektrum DSM2 and DSMX transmitters, ensuring compatibility with the entire range of Spektrum radio systems available on the UK RC market.
- SRXL2/Bind/Program/Battery Servo Header — A dedicated servo header provides multiple connection options, allowing you to connect smart devices, program and update the receiver firmware, use traditional bind plugs if preferred, or connect an external battery for testing and configuration purposes.
- End-Pin Output Configuration — The receiver features end-pin output pins specifically designed for straightforward, compact installation in modern aircraft, simplifying integration into tight spaces whilst maintaining clean wiring runs.
Technical Performance
The AR8020T operates across the industry-standard 2.4GHz frequency band, employing DSMX modulation technology for robust, interference-resistant signal transmission. The receiver accepts input voltages ranging from 3.5V to 9V, making it compatible with a wide spectrum of battery configurations commonly used in RC aircraft. With full-range telemetry capability, this receiver can transmit telemetry data across the complete operational range of your aircraft, not just at closer distances like some competing systems. The integrated barometer has been specifically engineered to provide both altitude data and variometer (vertical speed) information with sufficient accuracy for serious RC pilots. The receiver's dual-antenna design with 6.1-inch antenna elements ensures comprehensive RF coverage regardless of your aircraft's attitude or position in the sky, a critical consideration for reliable long-range flying. The compact construction, measuring just 1.92 inches in length, 1.18 inches in width, and 0.59 inches in height, allows installation in aircraft ranging from small parkflyer designs up to large giant-scale models. The 0.56-ounce weight minimises its impact on your aircraft's total weight budget, preserving the performance characteristics of even weight-sensitive designs. When paired with a compatible Spektrum Smart ESC, the one-wire telemetry integration eliminates the complexity of external telemetry modules whilst providing instant access to critical performance data including battery voltage, discharge current, motor temperature, and RPM. The receiver's forward programming capability allows channel-by-channel failsafe configuration without requiring computer software installation, a significant convenience advantage for field adjustments and customisation.
