First, never underestimate the "simple" looks of an outrigger hydro. If they could be just thrown together, more of us would build them. Yes, you could build one that would run but that's it. Listen to the others that have built their own or manufacture them, they talk of angles in 1/2 degrees that make the difference in handling and speed. The commercially made ones go for sometimes years of testing before they hit the market. Any R/C boat design, be it a mono, tunnel or hydro can be more complex that what it appears at a casual glance, John Finch talked in an article that he did for RCBM about how a bead of CA along the bottom of a hull can change the boats handling characteristics.
I'm not deterring you, just letting you know what you're in for. One member in here told me that he doesn't have instructions with his 'rigger kits because if you don't know how to put one together, you're not ready for it. You'd immediately know his name but I won't say who it is.
