Cool Beans! How did that work out?
Amazing how separate builds can com up with the same idea, even at different scales. I'm planning a 30 ft dual-sternwheeler. Plan to use two electric scooter(sit-on type. Looks like a modernized Vespa) motors, and roto-tiller reduction drives. From that, I'm going to be driving two Pitman's, through a mechanism I just found, on each wheel, with two wheels at the stern. She'll be able to turn within her own length, do turns from dockside, etc.
