MateksysSKU: Mateksys-ELRS-R24-V

Sale priceUSD $35.90


  • Specific for the Gliders and other fixed-wings. Small in form factor, It can be installed in gliders with restricted payload bays such as DLG’s and high performance slopers. Not needing to install an additional altimeter/variometer also saves room and weight.
  • The built in barometer provides vertical speed telemetry. The variometer sounds 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 will also give you other telemetry data like battery voltage, current and GPS related.
