Agreed! It has a need (no pitch physical dive plane control), so you're given a requirement. Require some form of depth and/or pitch control w/o the addition of stern planes to make it authentic to the prototype.
Now some of us, myself included, may elect to solve the requirement by forgoing exactly duplicating the prototype, by the use of clear stern planes. Ray Mason uses clear bow planes on his Disney NAUTILUS and rear fixed clear vanes to keep it level. As possibly the first operation Disney NAUTILUS, it was his solution to a requirement to even dive while maintaining a semblance of depth control.
Bob Martin met this requirement by conceiving and using a pitch propeller shaft to maintain pitch control.
BOTH solutions meet the requirement, yet aren't "true" to the design intent of Mr. Goff. (Purist rivet counters may now fling arrows at the semi scale lowlifes)
You can chose one the two above, or select a different solution. Still meeting the requirement.
Too be honest, I would go with simple gas ballast, and steal Bob's pitch prop as the simpler (to build, test, operate), but that's me and follows my build philosophy.
Funny enough, I really am a keep it simple stupid guy, while trying to enjoy the latest tech. Just enough to get the job done, reliably and consistently.
Unlike Capt. Frank Salerno and the ever evolving SSRN SEAVIEW. By the time he's done adding features he'll be able to make love to it.
