Bill you could be on to it. It really is a very simple addition. I hope to try it this weekend in clear water and will see how it goes. In someways moving downward in a head up attitude seems like an advantage, in other ways perhaps not. Hope to know more about that soon. Body attitude is important. The fastest, more efficient way I discovered to use the Aqueon as a teenager was inverted when swimming horizontally. Something about muscle function but aside from normal issues with sinuses while inverted you could really move out that way. Hope something similar kicks in using the mod.
I haven't met Cal in person, you were fortunate to do so. He got a kick out of the article. I will direct him to your comments and thanks.
Something put me in mind to fly underwater, that aside from using a Rebikoff Remora that has airplane-like controls, in my teens and early 20's for reef surveys. That is aerobatic flying. There is something addictive about throwing maneuvers through clear air at high speed. That aside from nausea from too many high G spins too fast after a time. Anyway, I found a reduced but similar sensation from free diving with an electric DPV. Intertia sports, gotta love 'em.
More antique technology, but fun! The Remora, very similar to the self contained Pegasus shown below with the photogrammetric camera on this nose. The Remora instead of having an expensive payload of silver-zinc batteries towed a whaler and generator by a power umbilical. It was heavy in air but fast in the water. It was a great stable platform for still, video and photogrammetric bottom surveys. It was fun to power dive to the bottom free diving and then pull out with the joy stick before plowing in. We used re-engineered versions in the '70's and early '80's. Wasn't born when Dimitri first brought the Pegasus into being.
