FrSky RX4R + RXSR + Sbus to PWM decoder wiring

Recommended Posts


Anyone worked out the correct way to wire up the brilliantly small RX4R to the Sbus to PWM decoder to give 7 channels of PWM, and add the tiny RXSR redundancy receiver too?

All the internet diagrams have been hijacked by the drone guys.

What settings?

Does Telemetry need to be disabled on either of the receivers?

Fitting this into my Q12 to hopefully improve the range I got from the X4R + Sbus decoder which was marginal at last year’s Nat's.

All info welcomed.
