Long before LSA the Posidoplane did indeed once exist- 50+ years ago. It was called the Ercoupe. No stick or rudder pedals (= no ppO2 readouts), only a steering wheel that poorly interconnected the two.

Ha! When I was working on my SEL airplane in 2001, I took a 1.5 hour ride with a old retired doctor in his Ercoupe (no rudder modifications). They're beautiful planes and if you keep the aluminum polished, as this guy's was, it looks like a sleek fighter trainer or something. As you have well explained that is VERY MUCH not the case. When we took off the winds were calm, but by the time we were ready to land, we had a 10 kt crosswind, which might as well be 30 in that thing. You can't crab so you have to dip the wing into the wind and hope you don't have too much side-drift for gear to handle. We did two very scary touch-and-go's trying to get it down and finally stuck it on the 3rd try during a lull in the wind. I played it off like it was no big deal (I fly UH-60's for the Army) but inside, I was crying and wanted my mommy.

Jokes aside, I read the MK VI White Paper this week and I have to say Dr. Stone's logic behind the self-calibrating cells seems pretty solid. There ARE some potentially dangerous situations with 3-cell voting logic, and he suggested that if he were to make an expeditionary version, it would have an additional primary cell anyway.

I'm embarrased to say that I don't know as much as probably I should about the inner workings of head units. What do the homebuilt geeks and "smart guys" think of his 2-cell system? Comments aside about the this particular MK VI unit, Is this "self-calibrating cell" configuration the future of CCR's?
