For me, this was the hardest realm of the RC world to break into. There is not a lot of information posted on the web for beginners. Also the up front cash outlay is large. I don't think you can get a sub in the water for less then $700. To help out the prospective submarine commander, I'm logging what I've discovered and my results. Please remember that I'm a beginner at submarines and that not all the information may be correct. If you do find any glaring errors please email me at the address listed on my home page. Ok, with that being said, let's begin.
