ELRS receiver with variometer specifically designed for gliders and other fixed-wings. Its small form factor and integrated variometer makes it ideal to install when you have restricted space and saves you on weight.
The built in barometer provides vertical speed telemetry. The variometer sends both ascending and descending tones, so you will know whether you are in lift or sink without having to look at your transmitter.
With ExpressLRS firmware and CRSF protocol, this receiver will also give you other telemetry data like battery voltage, current and GPS related info.
