I now have completed the basic hull for the Junior subs. I am selling them made from the same material as the Submarine707II. A rigid plastic from 3d print. It is 12 inches long and has the front mounted prop. I designed this to be a dynamic boat with enough room for a small 2.5 inch x 8 inch cylinder. I am selling these for $400 + shipping within the continental US only.
NOTE: You should be a skilled modeler if you intend to convert this to RC.
