use of 458MHz modules

As a newcommer I have no rc equipment at he moment and the only new stuff is the 2.4GHz band with all its problems. I've seen various 458MHz RF modules that would seem to be able to form the basis of a RC system, whilst there are various posts about the commercial modules at the USA frequencies has anybody built a system with the bare 458MHz modules?

I have also seen a video about swapping the provided 2.4GHz aerial for a longer length of co-ax so that the aerial can poke out of the water via the scope/snorkel that would at least allows running at scope depth. It seems to either rely on the Rx having the aerial wire on a connector or being able to solder fine wires. I could solder that but its easier to just plug a small connector onto the Rx board, so I was wondering if any one had tried that with currently avaialble rc kit, and if so which Rx have a connector?

I'm think of actual control not a telemetry return feed.

if you search this site using the term "openlrs" you will find an entire set of threads on how David has built and uses 458mhz equipment exclusively in several of his submarnies.
