Just had my first run of a 30" Crackerbox I built., took some old plans and scaled them up 150% as I wanted a larger size. I'm running a Traxxas 550 12 turn motor and speed control out of my old 1/10 Slash truck, and as I'm not racing using a surface prop out the back rather than under the hull.
Speed was OK but the turning circle is much wider than I'd like. I think the rudder is undersized as its really more for a 1/10 scale boat, it currently extends about 2" below the hull and is about 1" wide My question is shoudl I extend the rudder deeper into the water, use a wider (bigger) one, or both?
I won't be racing, this was just built for fun on the pond and I always think bigger looks better
