I was told it was because of the non-sheeted LE. Four Stars make the same howl. Sounds great.
Guess I'll find out when I get my 4*60 airborne. BTW, the US40 has a sheeted LE.
Went flying again today even though it was pretty breezy - 15-20mph. Gaining a lot of confidence in the wind now - which is particularly useful since it's usually more windy than not here in the upper midwest - except when I want to go sailing...
