Bill, I know you have a vested interest in getting the Powersport design out there, and  I realize that it seems to be a basically an ok (though quite pricey) product (with no current production and apparently no support).

That does not justify advising avoidance of designs that have a far more proven track record than the half-dozen or so Powersport drives that have flown.
