Why
We want to use shorter antenna feed lines for ELRS and we have a big drone for Big Quad 2025
lower loss feed lines require them to be short or heavier
want to stick with 2.4ghz elrs to get the bandwidth advantage as we’re streaming telemetry and rc over elrs.
What
Possible Solutions
Use two RXes connect to pixhawk and add features to ardupilto and ELRS to support choosing the best one to use. one Rx on each side of the drone
Custom hardware to run SPI over a private CAN bus (so not datarate issues) between LR1121 boards which allows for normal ELRS firmware and ardupilot at the cost of more complex custom hardware
