Multiple RC receivers and Transmitters

Hello All,

I have a use case that I am working on where my PX4-powered UAV travels from Location A to Location B and back, which are 10 kilometers apart. I am currently using a Futaba R7108SB receiver onboard the UAV using SBUS, paired with a Futaba T16IZ super transmitter. The UAV will be flown in mission mode to travel from Location A to Location B. I want to integrate a second receiver and transmitter pair so that two people at each location can take over control if necessary.

Is there an adapter or solution that allows connecting both RC receivers to the RC input bus on autopilot to facilitate this setup and still execute the mission?

Thank you for your assistance.
