Video on Parasol structures, Part 2


The  part one of this video pair was viewed 425 times the day it was posted on my Youtube page. Not world record setting, but still very popular by my standards. It was well received on Pietenpol sites. Here is a follow on which expands a bit on the original ideas explained in round one.




Because of how I collected the photos, some the images are not going to be high definition. I apologize in advance, but I wanted to get the conceptual information into the discussion as a quick follow on to complete the discussion on the structure of parasols.

Note to builders of Pietenpols with other engines:  There was a comment made on the Pietenpol FB page about me “Withholding Information” about the construction of  Pietenpols from builders who choose engines other than Corvairs.  This is pure BS, and it is a fake claim.  The two videos in this series benefit all Piet builders, posting them on youtube publicly hardly is withholding them. Likewise, All of the data I developed years ago with Ryan Mueller on the weight and balance of Pietenpols with all kinds of engines was shared with everyone through the newsletter, and will shortly be available in notebook form through the Brodhead gang. I have never refused to help any builder with any aspect of his Pietenpol, no matter what engine he chose. Every article I ever wrote about Pietenpols has always been publicly available here: Corvair – Pietenpol Reference page.   I’ll share what I know with just about anyone, no matter if they are a Corvair builder or not, even people I find distasteful; my devout allegiance to aviation safety isn’t conditional on being paid nor finding people pleasant, it is about protecting unwitting passengers who will inevitably fly in these planes.


The only thing we do privately is our “Piet-vair” Discussion Group where we talk about Corvair specific things. Anyone suggesting I have ever withheld safety information from another homebuilder is making and incredibly offensive false statement.




About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at and in more than 50 magazine articles.
