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.
