Wow: Lots of good info, thanks everyone. My plane is not certified, yet. LSA rules state 138 for top speed, HDS top speed 150. Stall speed Dual is LSA 51, HDS is 54. It sure seems that I for peace of mind should change wings. I'm waiting for a Zenith reply. Is that wishful thinking?

You might also check out Klaus Truemper's website. His wing root fairings
reduced his HDS stall speed to LSA levels. The fairings had other
performance benefits. See

Will an HDS really do 150? But even if it will that is easy to fix with a change in prop pitch and and entry in the POH that what ever RPM makes you exceed 138 not for cruise.
