RE: catamaran hull on ebay
That hull come up alot. I think it looks pretty good. Nice look. Looks to be a capable design. I've never seen a full build thread for one though to know if there are any short commings. As mentioned in a 32 you can manage pretty well with a single motor. You are adding lots of $ and lots of weight to put two motors in, and an XL motor and 4-6S lipo should move that boat very well. Read Ryans sticky about setup at the top of the electric page. You are on track as the first step is choosing a hull. I'm building a scracth balsa cat that's 29" long and it getting a an 8XL and 4S. I'm hoping for clost to 50mph with it.
