I don't know what's up yet with the Mean Machine 18 as it might be out.
www.funrcboats.com is one of the dealers for them, shoot Debbie an e-mail. I've seen the prototypes and for the price it's already loaded with things that others have to put on later but I haven't seen the production version yet. One thing about it is that later on you could drop a hot .21 into it.
