FrSky Radio System Notes
FrSky Rx Failsafe
FrSky receivers (status summer 2012) need a special sequence for disabling the built-in FrSky failsafe. If that is enabled (by default), the AutoQuad controller will NEVER detect a failsafe and trigger a failsafe event. For now the following procedure seems to disable the
failsafe. Please test in the GroundControlStation if the AutoQuad detects a lost signal when the radio is shut down.
- Power off the transmitter, power off the receiver.
- Now ONLY power on the receiver (red light will blink), push the receiver bind button ONCE.
- Power off the receiver. Failsafe is now disabled.
At this time all FrSky X-series S.Bus receivers are known to work with AQ (X8R, X6R, X4R). A great option is the small but full-featured FrSky X4R (pictured at left). 16 channels, full-range, replaceable antennas, with great telemetry options. It can even be easily modified so that an S.Bus inverter is not required. See here for details.
Don’t forget to disable failsafe, as described above.
