I really don't know what all this R/C business is about.
I have a MacGregor Digimac and a Mini-Hex from the 70s and a couple of Acoms or Hi-tech or whatever they're called. They all work just fine. I'm not into lights, horns, rotating washing lines and all the rest,I only want left, right, go, stop. So am I OK just using my 27 Meg (which was all I even knew about till coming on here!) on my local river. I don't have a club, just local waters in bow and arrow country.
Actually it's all the same if I ain't, since I will not be replacing what already works, though it must be said the new stuff is so very cheap compared with when my earlier stuff was bought. presumably because it's made in the east.
