I highly suggest against the ultra lx comp, I have one and it is nothing but problem after problem for me, and the force 26 engine is weak for it's size, and can't take a beating at all, you'll throw the rod if it overheats it happened to me the first time it over heated after 4 tanks. I would suugest the other buggy's that are listed up top, I have heard and read nothing but good things about them. If you want to get heavy into racing I would suggest a pro-spec kit, the MBX-5 pro spec kit is damn nice, very tight takes a beating, and parts are pretty easy to get. The difference between a pro spec and a rtr is prospec does not come with engine, or electronics, but they are much higher qaulity, you get all of the optional parts with them.
