Hey doc, maybe you can help an old Texan to understand these new fangled radio things...
I'm getting lost in the various explanations of how to use the Archer M+ as a redundant reciever.
Say I have an Archer SR as primary and I want to use an m+ or two m+ as redundant. I understand, kind of, that the x20 binds to the SR on 2.4 ghz and the m+ on 900 mhz, What I'm getting list on is how the physical connection is made to the archer SR. The details here says that the m+ can firmware update wirelessly..ok..does that mean it's also connecting via 900 mhz to the SR? If so, then how in the world do you power the little sucker.
I know the mustang has accommodations for 2 redundant recievers built into the fuselage (minus hook and loop, but yeah) I'm just not sure of the wiring needed to set them up.
I know there has to be some type of connection between them, there's there's no servo control if loss of signal to the primary.
I figure with some of the wing flexing you do with them sneeze on it, it breaks, (

)birds you fly, you might be using one back towards the tails somewhere.
Can you enlighten me?
