This is the Spektrum RC SR6200A 6-Channel 2.4GHz DSMR Surface Receiver with Telemetry & AVC. Built around frequency-agile DSMR technology, the Spektrum SR6200A 6-channel DSMR receiver delivers excellent range and response along with unbeatable signal security in a compact, easy-to-install package. AVC (Active Vehicle Control) technology increases your stability on tough terrain. Compatible with innovative Smart Technology, the AR6200A receiver also provides real-time telemetry data when used with a Smart ESC and Smart battery. The SR6200A receiver throttle port includes Smart Throttle. This port will automatically detect when a Smart throttle electronic speed control is plugged in and the throttle port will begin to operate in Smart throttle mode. When combined with Smart ESC and Spektrum Smart LiPo batteries, the SR6200A can pass along a multitude of helpful telemetry and battery data with no additional modules, sensors or wires. If a standard ESC or servo is plugged into the throttle port on the SR6100AT receiver, the throttle port will operate normally like any conventional receiver.
