Open cockpit -4
There were pictures of a silver -4 with "two hole" open cockpit I saw a couple years ago. Supposedly quickly interhangable with the bubble canopy via the hing pin. He had to cut down the roll bar (bad in flip-over). There is also a yellow RV-3 open cockpit in Hawaii that looks cool ..his report is that its not bad at all. I am playing with the idea to try it on mine sometime in the future, and have the interchangability with the bubble.
