Airspeed Sensor for SBUS2

  • Indicated Airspeed (IAS):  ~10...450km/h
  • Weight: ~8g. incl. 30cm SBUS2 cable
  • size ~22x20x13mm

18MZ /14SG & 18SZ/16SZ have different sensor IDs in use for the airspeed sensor and therefore 18SZ / 16SZ require different method to install the sensor:

    • Futaba 18MZ v2.5.1 & 14SG v6 Firmware or newer:
      • Register the sensor to TX as any genuine Futaba sensor
    • Futaba 18SZ / 16SZ v3.5 firmware - Register function not working:
      • Use change slot menu functionality to select desired slot
      • Select "airspeed" sensor manually for the corresponding slot in sensor list of TX


Actual telemetry log from the testfly with my Boomerang Elan (click for full size):
  •  Short flight: take-off, some flying, landing, total stop, and taxiing on runway at the end.
  • Red line shows Indicated Airspeed as measured by the the Airspeed sensor (km/h)
  • Blue line is Altitude (m) for reference (as measured by standard futaba altimeter; it suffers Jet engine pressure disturbance, hence some inconsistent altitude readings) 
  • timeline is "minutes"
