The Australian Model Aeronautical Association (MAAA) rules governing FPV racing require that the multirotor be equipped with a failsafe system that immediately cuts the motors when "radio signal is lost".
I am not wishing to debate the merits (or otherwise) of this Rule here, that is for another place and time. While this is happening I cannot see anything in the Arducopter Wiki in the failsafe section that would enable Arducopter users to comply with this rule. Is there a way currently to achieve it please?
The "radio" referred to may include both the control radio and the VTx, this is one issue to be clarified.
Thanks for any help.

you can have that by using reciever's failsafe, program it with position for throttle(0%) and mode(stabilize) - and set THR_MIN so low that motors don't spin on arming.
Of course, "immediately" is clueless B.S. from whoever made that rule, because every system accepts some amount of packets to be lost before going to failsafe, so while Graupner can be configured up to 2 seconds, every system have a delay before doing so.. so there should be a defined allowed time to shdn, otherwise noone will run the default 250ms that many systems have as default.
The Australian Rules are, in this and other respects, just a copy of the draft FAI Rules.
