To give you all an idea of what I've got, here are some of my fleet: http://www.rcflix.com/photopost/show...ge=1&ppuser=15 . Some are just shots of friends and stuff but there are a few videos to boot.
My main thing right now is taking R/C truck engines and mounting them in small hulls to see how fast I can get them to go. It started off as having a bunch of nitro truck parts laying around after I got into boats so I thought that I'd see what I could do with those pieces. You'll see some of my larger boats in there also.
