I'm just wondering if these manufacturers know something we don't about the
final rule or on the other hand, are they building airplanes to a rule that
they don't understand?

Maybe after watching all the "fat" ultralights fly around vertually unmolested
they think they can bend the new rules as well?

I'd almost bet that Rotax will introduce a derated 912, somewhere around 75-80
Hp, and call it something like a 912LS just for the new LSA's. And one wonders
how long before the owners discover that it's probably pretty easy and
inexpensive to convert them back to "normal" 912's.

"course that wouldn't be legal, at least not any more than 350lb 103's.........
