Hi all,

A mate of mine in South Africa who owns an HDS has recently heard of another guy out in SA who has, apparently with appropriate engineering (aeronautical) and local civil aviation authority, put extensions essentially to the existing wing design and is allegedly in flight testing. From what I understand the individual is experiencing significant increases in performance specifically cruise and climb.

I have never heard of anyone doing this before and was frankly a bit sceptical. Has anyone else ever heard of this being done? With the higher fleet numbers in the US if it has been done I would expected it to be done first in the US.

No unfortunately not mate. The chap with the aircraft is quite far away so I am relying on another guy to mail them to me.



Hey James,

Can you tell me the names of these guys?  Anyone doing much work on an experimental probably has a web presence somewhere.  I might be able to find him with a few web searches.



Hi all
If we do gt photos or any info I would love a copy,I have a hds with jab 3300 and inflite adjustable great with one up but a little interesting with 2 on a hot day the extension would solve this.
