Quite a few years ago , I was going to build one of these. I wanted it to be build like the original IE two axle steer, full suspension , six wheel drive , working diffs , and work on the water. My problem was and still is LOM ( lack of money ) !And having the tapering narrow lower hull makes it difficult to shoehorn what I had into the hull. I still have plans to do it in the future tho .
keep us posted on your progress.
