If I was of the mind that dual receivers were necessary (and I am not) this is the way I would do it. Then you have true redundancy, as long as the "bad" receiver does not lock over everything hard, or whatever.

I am still waiting for the dual transmitter set up. I have never had a RX fail, but I have had 2 TX's die in my hands (encoder board failed in flight in one, fuse blew in another). I have also seen two guys literally have the gimbals come off in their hands !! But no one ever obsess about TX failure. Too rare I guess.

One thing that does amuse me is the terrible installations I see. RXs that are strapped to wing tubes, stuck to fuse sides and such. Oh yeah, a little Velcro is used, but that hardly insolates the vibration of the engine. It intrigues me that we used to wrap our RXs like they were made of glass when we flew smaller planes. Now we treat them like they are indestructible and then obsess about using two for redundancy sake.

Oh well. The Emcotec stuff is solid and like I siad, if I really felt the need for dual RXs this is the solution I'd use.
