Need a real controller- sit down seat, wheel, throttle, shifter, drive and tabs. Sell it thru Trick marine!
I like the ability to have adjustability of the X-dim, prop pitch, drive ratio, then with only 2-3 hulls you can have more importance on setup.
Make it for the X-box for the kids and make mine PC with 50"plasma screen and sitdown controller.
Put a little water sprayer on the controller to spray the user with splash and soak them if you crash or roll!
