In the UK we too have the same 400ft limitation and only a complete retard would fly anything beyond their line of sight."AMA's Safety Code include the requirement to see and avoid manned aircraft and maintain model aircraft operations within visual line of sight and below 400ft AGL"-Direct quote from AMA. You can get hefty fines if you are flying beyond your visual LOS
I wasn't making the point about distance per say from R9M or crossfire, more the technology advancements and the fact its a broader operating band and less conjested than the 2.4ghz band width used by Spektrum. I was also trying to point out in directly that the R9M system was introduced by FRsky. Plus advancement in open source software has helped Open Tx to become so popular.
I watch a of lot of You tube and chat on other forums and its very apparent to me. That FRsky is a very popular operating system across the world.
In fact until you pointed out the issues your club members have been experiencing, with FRsky equipment and crashes I had never heard anyone before having issues with FRsky or there system
