2.4ghz systems work for any model situation in today’s world, the limitations of specific channels and frequency’s are only applied to am/fm systems 40,27 and 35 MHz ....
There are issues with 2.4 systems in boats however as 2.4 has a hard time penetrating water surfaces, meaning should you fit a 2.4 to your boat it’s best to mount the receiver in the boat as high as possible. (Avoid using 2.4 in subs, that’s what the 40mhz systems are great for... Navy system)
Range can also be an issue depending on the unit you have... the radio links tend to be shorter range and when in a boat decreased further. However that said in a boat when u can’t see it you can’t control it either.... so just keep it in sight!
The other issue with 2.4 is they do require 6v constantly.... rechargeable battery’s sadly don’t do the job well enough ( they are actually 1.25v not 1.5 at best) so avoid using those.... if your having radio issues and it’s cutting out etc it’s either radio signal/distance or poor battery’s...
Just a heads up on that... radio links are a good option my father has two sets and many of my older club members use them... I opted for the spectrum set.... so my issues are different!
