When you say the reception 'drops from 100%' what do you mean?

Surely a PCM or 2.4 RX has a valid signal or not? I'm pretty sure that the RRScan't detect the strength of a PCMor 2.4 signal, only its presence or lack of. I'm trying to work out whether it actually does what people think it does (i.e true RXredundancy) or if it is just there in case one RXgoes into failsafe.

In my example about the power failure, if the RRSis solely looking for a failsafe signal, will it switch to the good RXor will it contine to use the failed RXwhilst waiting for a failsafe signal? Therefore having a perfectly good RX on board that it won't use. The instructions aren't too clear about the logic used.

Zack, if you havetheRRS, could you run a test and unplug the 'in use' RXfailsafe plug and seeif theRRSswitches over?
