Technical

The original intent of this whole project was to document as many technical features of the Nasty as could be rounded up. Fortunately you the readers have provided lots of great material to add to this section! These manuals have been re-scanned and converted to text for readability. That removed the greasy hand prints and bad photocopy quality. Many of the drawings and illustrations are low quality so that they will load faster. Someday I hope to rescan those pictures and make a HiRes version available to those with the patience to wait or a broadband internet connection for fast loading.

Disclaimer: Do not try to Operate your PTF Nasty or Osprey with these manuals, This information is only for those "inquiring minds that want to know."
