BRICKNICK-I spent about 25 years seriously racing model boats. Traveled all over the U.S. competing, but in the nitro boats. I also did some R&D work in FE (fast electric) and set a few IMPBA records so I know a bit about them also. This was a long time ago when we used 05 motors and ni-cad batteries but the use of brushless motors and lipo's have drastically changed FE boats. I don't know what type of boat you are looking for but if you want to go really fast, you should check out "zippkits". A friend of mine designed these boats and they are not much to look at but they handle great and are bad fast and are good in rough water. Here is a link-

Look at the videos if you want to see them in action. They have kits if you want to build your own or you can buy them pre-built and I think they may offer a ready-to-run version. Hope this helps
