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"
