Those are they day I am happy to have RSSI (Received Signal Strength Indicator) telemetry.Īlso note that for the newer ACCESS RXs, a better indicator is the VFR (Valid Frame Rate) number. The symptom was the RSSI rapidly dropping as I was taxing the model to the runway. On two occasions I had receivers 'go bad' seemingly just by sitting on a shelf. For models equipped with a gas engine, the test should be done with the engine running (and the plane secured to the ground). If running ACCESS receives in OTX mode using the X10 make sure you set the RSSI warning level to 35 and 32 db.įor what is worth, I always perform a range test before a new model maiden, or when I do any modification to the receiver/antenna configuration. So your body is mostly water, also flying in the rain or behind trees is risky.

This is because 2.4g is readily absorbed by water.

You maybe aware that Micro wave ovens operate at 2.4g. So best to face your model during range check. Be aware if you are walking away from your model and your body is between the TX and the model your body will be attenuating the Transmitter signal. Under Range Check Mode, the RF power would be decreased and Range distance toġ/30 -1/10 that of Normal Mode.' So in range check you should see at leased 30 to 50 meters of range before RSSI warnings. Loss of signal both during range check and during the flight. Reflections from nearby metal fences, concrete buildings or trees can cause The FRsky manual typical say something like 'Ī pre-flight range check should be done before each flying session. So what this does is test your electronic components, antenna locations and orientation etc without having to walk away long distances from your model. Range does mean 'Range Test' This function reduces the Transmitter RF power from 100mw to approx 1mw.
