I have to agree with Wave Waker. Dumas is alot of fun. I converted mine to elec and run nitro on the TS2.
Plus, building the dumas is good experience if you like that. Gives you a sense of satisfaction seeing the boat YOU built hooning around. Dumas is shorter than the TS2, more kind of a stunt/mono boat, but will plane very well when setup correctly. I found the Dumas does prefer smooth glass like water.
Get them both mate?
