The reason I raise the issue is -- the Grumman Tiger has a very similar sliding canopy and at certain speeds (Vfe and below) you can open the slider in-flight to enjoy that "open cockpit" experience.
I was just wondering if any had ever tried it on an RV -- or if it is structurally outside the envelope.
While I did consider the Pitts (and even the Hevle Classic -- which is a beautiful two-seat Fly Baby) as kit choices. They weren't suitable to my primary mission of cross-country.
