Rob Nachtrieb's Snazzoramic Website

Updated 02 Sep 2010.  
Thank you for checking up on my progress.  CONSTRUCTION OF THE COZY IS ON HOLD while I go back to school.  Please check back in June 2012.  





I'm building a Cozy.  "What's that?"  I'm glad you asked!  
The Cozy Mk IV homebuilt airplane (photo above) is a derivative of Burt Rutan's Long-EZ, modified by Nat Puffer to seat four.  Using the same solid-core moldless fiberglass construction techniques pioneered by Rutan, the Cozy offers long-distance, high-speed cruise with comfort and economy.  Find out more details from Marc Zeitlin's site, or buy the plans and parts for one of your own from Aircraft Spruce.

"So When Will You Be Done?"

Um, not soon.  But please keep asking!  According to Kitplanes, only about 12% of homebuilt aircraft plans sold are actually completed.  Please help me to be in that twelve percent!  If you notice a lapse in website updates, please cajole to get back into the shop.
