The CB Elektronics HSS-330 is a dynamic pressure sensor that provides real-time indicated airspeed in kilometers or miles per hour of your model. Measurement is done through a pitot tube that measures the difference between the air pressure and static air pressure after which the information is broadcasted over the telemetry channel providing valuable data such as air speed and stall speed.

The pilot is notified of an imminent stall of his airplane through the Graupner HoTT telemetry downlink.

The Graupner HSS-330 works with any Graupner radio. The HSS-330 is connected directly to the receiver’s telemetry port and is identified as GPS sensor. Stall speed calibration is required for the model prior to operation through test flights where the model stall speed is determined.
