Online Community of Zenith Builders and Flyers
I own an HDS and have not heard of anyone in the US making extensions for an HDS. I have heard of folks changing the wings out for a set of HD wings to get the stall speed lower.
I have been thinking about this for sometime but just not sure where to start but apparently Zenith was thinking along these same lines before producing the XL, here's part of an email exchange with a guy who has a set of 25' HDS wings instead of the standard 23'. I would love to add 12" or 18" to each wing I wish Zenith would create a factory approved kit for us, Id buy one.
To make a long story shorter, I accidentally learned about the factory built prototype wings that sat in storage at the Zenith factory for many years. There were no drawings for them and they were long forgotten, but to me, they were beautiful and exactly what would make my beloved Zodiac perfect.
I couldn't have been happier - they were lively and responsive in flight and I couldn't stop looking at them, they were beautiful and I couldn't believe what a huge difference that extra two feet of span made. I even liked them much better than the looks of the HDS wings that originally wanted.
I've been in contact with the guy referenced in my October 21st email and have some additional information. He provided a picture and dimensions which I have used to create a sketch which are in the attached file. It would be great if we could get Zenith to help us develop a modification to the HDS wing.
Thank you for posting that information.
It looks like he extended the wing out by not cutting the lower skin and beveling to make the wing tip. Maybe the top and lower skin are a little longer. It is hard to know much more from the photograph. I was hoping that it was some kind of retro-fit to an existing wing; guess not.
The thing to keep in mind with this extended wing is it's not a user modification, this was built by Zenith as a design concept prior to the XL design. Unfortunately per Zenith they have no drawings, etc to help us with this endeavor, my wish is someone at Zenith will read this and offer us some help.
Did you ever get any pictures of the wing extensions?
