Pete, 32 - so not too many, thanks for asking.
Thanks for the replies fellas.
That list is a great help Brent - starting to make sense of it all.
One thing though. What did you mean by:-
"The SP had extras that made the LSA55 a better aircraft (like the stretched fuselage), but rather than spend a million re-certifying, the factory LSA55 stayed the same and the Kit SP was sold and eventually in a way evolved into the J160."
Why were the extras detrimental? I'm guessing the longer fuse hampered the performance???
