TWITT NOW HAS AVAILABLE
A VHS TAPE OF AL'S PRESENTATION IN AN EXPANDED VERSION

We have recorded Al Bowers presentation on the history of Horten sailplanes and his detailed analysis of the Horten Xc ultralight sailplane.  This is an expanded version of what was seen at Tehachapi, since he had more time to cover the topic areas and answer questions from the group.  It is an excellent talk and gives you some unique insights from Al's perspective that can't be caught in any written version.

The package includes a 1 1/2 hour VHS tape shot with a professional grade camera and is of very good quality.  In order to work your way through the various slides that Al used to demonstrate the results of his research and analysis, we are including a copy of the complete set along with the video tape. (A small sample of these slides are shown below.)

We currently have these tapes in stock and ready for immediate shipment on a first come, first served basis.  If demand warrants, we will do another commercial run to restock more quickly and try to provide you with reasonably quick service.

This package is available for the price of $10.00 US, postage paid (add $3.00 for overseas shipment). See below for credit card orders.

Bill Moyes' (Australia) interpretation in 1991of the Horten Xc with a 15m span.  Built with glass, carbon fiber, foam and aluminum versus a built-up wooden structure as originally by Horten. 
   Per Philippe Vigneron, an Australia Gliding article in the August '91 issue offered the following:  'It appears that two German modellers had corresponded with Reimar Horten and had built a model Horten wing, then won a world championship with it.  This apparently pleased Horten to the extent that he offered them drawings of his latest design, the Piernifero 3.  The two modellers could not make use of them so Bill Moyes offered to finance the construction of a prototype.  How Bill met the modellers is not clear.  He paid the modeller's fares to Australia where they spet six months in his hang glider factory building the Horten.' 
   Al Bowers has been in contact with Bill Moyes about his project and has indicated there may be more information to come on this project which could enhance Al's attempts to finish his analysis of the H Xc.
