But it is nice to know that I know have an entire suite of 4 different protocols in the 900mhz frequency range to test and post my results on.
Because so many people have problems with frsky r9, I have been able to pick up modules for around £20 each because no one wants them.
I looked at Crossfire but its far more expensive, The mavlink telemetry implementation has a lot of problems and there is no way to have a 1W bidirectional link. ExpressLRS is all about low latency, there is a version for mavlink but its experimental at the moment. The only other options for that are dragonlink and the RFD900 but you are still looking at over £200 for a set compared to £40 for a pair of R9M modules.
