No, I haven't done the beanie mod. I am scratch building a 750 and decided it didn't really need it because the windshield/roof junction is fairly gradual. Now Zenith have done their own beanie mod to the Edition 3 CH750. I might incorporate their changes.
My idea was instead of forming an aluminum sheet rib like in the wings (as per Joe Spencer's mod), I would use some half inch aluminum tubing and bend it to a rib profile and place it in the middle of the cabin roof and rivet it to the lexan. This would provide some additional stiffness. The tubing that I am talking about is the type often used as wing rib battens used in ultralight aircraft. I have some from an ultralight that I had that received damage to the wings. I am not sure this would work well; just an idea that I had.
Hi Alan. I have scratch built a 701 and currently live in NE Victoria, Yackandandah. I am moving to Townsville in January 2013. Love to have a chat. I have about 130 hours on my 701. I am about to bring it home to make some minor modifications.
All the best
