Redundant receiver for 3D flying

[gregg]

I have learned that 3D flying (particularly fast spins and tumbles) can lead to temporary RF signal dropout. I use Archer R6 rxs with access and qx7 and tandem x20 txs.

Since I have R6 rxs I am considering using them to make a redundant rx setup with one R6 the master, and another the assistant.

The master and assistant rxs both have the 6 pin plug plugged in the smartport: the sbus-out lead (white) from the assistant rx would be soldered to the sbus-in lead (blue) on the master rx. The +5v and gnd leads are also joined (soldered). I would also connect the external voltage sensor to the black, red and yellow smartport leads of the master r6. Both master and assistant have the same receiver number when registering and binding, with telemetry set on for the master and off for the assistant.

Rather than this amateur wiring exercise, is there a better more convenient solution? And if the above connections are incorrect I would appreciate advice....

I am planning to lodge a support request with frsky about this, it is one thing to not sell a lead suitable for the function that the rx is advertised to have, but another to expect the user to not only make their own lead but design it as well, maybe that is beyond the pale.

I am planning to purchase a R9 900mhz rx for my Tandem X20, but having studied the R9 manual and read more about it I am a bit worried because you can’t simply plug a MLVSS voltage sensor into a smartport as it does not have one. The R9 documentation says "Support S.Port / F.Port (Configurable in OpenTX / FrOS menu)", but like my redundant rx problem you have to find out how to make a connection lead yourself. It probably will be straightforward.

I just saw that there is a version of the R9 with a smartport, the R9 SX
