Reverse RCABS RC Submarine Ballast System

Thanks to George "Crazy Ivan" Protchenko for the great rendering of this alternative to Dr. Art Broder's elegant RCABS system!

Here are the "guts" of Pete Piekarski's USS Ohio's Reverse RCABS ballast system. Note the elongated tank forward -  two toilet flush floats glued together - and the blood pressure cuff inside a PVC pipe with holes cut out. The clear tube aft is where the electronics and pump live. Gell cell battery is at the bow.
