Last couple of days I've been playing hooky from the torpedo work and have been working up product to support the r/c'ing of the fine Revell 1/144 Type-214 and Type-212 kits. Lot of commonality between the the two submarines, so I'm getting some synergy from the dual effort.
Pictures are the masters for the type-214 fittings kit and a mock-up of the 212/214 SubDriver. This 1.25" SD will feature a LPB ballast sub-system. I had to devise a new type ballast tank vent valve, a sort of 'guillotine' type, that presented very little operating force yet was small enough to not increase the SD's sectional area significantly. Worked out pretty good -- you see the test-article just after some in-water testing. Like the control surface pushrods, the ballast vent will inter-connect to the internal servos through external magnetic pick-ups, eliminating the need of watertight seals between servo and linkages external of the SD.
You watch ... the moment I'm ready to go to market with these fittings kits and SD's, Revell will pull their tools off the production line!
David,
