This has got to be the most complete 21 hydro kit out there without someone actually building the boat for you. Tub, sponsons, boom tubes, all hardware, pre-sharpened turn fin, servo trays, Walt Baney tank, even a shaft oiler! Chris Wood put alot of thought into this and it shows. The in depth instruction manual takes you step by step through the build process which is surprisingly easy. For all that you get I would have to say that the $725 selling price is a heck of a good deal.
