N981MP is a standard Rutan Long Ez which I started in September 1981 (hence the N981MP)  while stationed at Fort Polk, LA.  After several transfers and breaks during construction I had first flight in August 2006 at Kissimmee Gateway Airport, Florida.  The airframe was completed 1995. At this time I decided not to use the Lycoming o-290 I had due to the cost of overhauling.  During this time I found a group of builders who were experimenting with the Mazda Rotary engine.  This caught my attention since I had owned an Mazda RX-7 sports car and thought the rotary engine had a great power-to-weight advantage.   By not going the standard aircraft engine route it took me another 8 years to finally integrate the rotary into the Long Ez airframe.  The biggest hurdle was building a cooling system that would fit into the narrow cowling of the Long Ez.

This site is currently under development.
