This would be a great set-up (tool) for testing out new hull designs.
If the hull design in question doesn't work out, toss only the hull, reuse the pod assembly. The time spent on it's construction, hook-up time, finishing, materials and the like is not wasted.[8D]
If a hull design deserves merit to be built as a unit, it can then be easily duplicated with permanent fixtures.
A removable rudder set-up would be ideal in this case, as it would also allow different rudder shapes and sizes to be tested at the same time.
If you get a chance to browse thru my posted pics (they're everywhere) you may be able to incorporate it's principle to your unit. It basically consists of two permanent hinge points (on the pod/pylon) and a hinge rod. The rudder (blade) itself has a coresponding hinge points. Remove the rudder(radio) linkage, pull the hinge rod and the rudder is off. Reverse process for installing.
I'm currently working on a new hull, and will take pics of this easy method and post 'em.
Again, great idea with many possible uses
