The Spektrum AR8020T 8-channel receiver is a DSM2® and DSMX® capable receiver with a compact design suitable for a variety of aircraft. It features full-range telemetry, an integrated barometer for providing altitude and variometer telemetry data. Additional telemetry sensors, sold separately, can be connected via the XBUS and temperature ports. It also includes an SRXL2 port for an SRXL2 receiver (sold separately) to add extra RF path redundancy. An SRXL2 / Bind / Program / Batt servo header is available for connecting smart devices, programming and updating the receiver, binding with a conventional bind plug, or connecting a battery. The AR8020T also has a bind button for easy binding without a plug and offers both SmartSafe technology and Hold Last Command, along with a preset failsafe option that can be configured through further programming. Additionally, the throttle channel connection is immediately compatible with Smart ESCs. Please note: The Spektrum transmitters DX7S and DX8 Gen 1 do not display altitude or variometer telemetry with the AR8020T receiver.
