RE: Enlarged Zirioli Turbinator 125% size
We found out that we can't use a 2" tube for the joiner with a two piece foam wing going out 18" into each panel and not breaking through the skins. We can fit a 1.5 with no problem so I'm getting some 2024 seamless tubing with .065wall from the supplier and moving forward with the wings as of today. Lots of delays with the work thing and the wifes health this past spring; but we are getting back on track for a either late fall 2012 or early spring 2013 test flight.
