01/30/2005. Remarks by builder/owner Mike Butts: "My aircraft started out its life as an Aventura UL which I purchased as parts. I constructed the aircraft from those parts and added many features such as the fully enclosed cockpit, hydraulic differential toe brakes, completely new instrument panel and all new fabric. N163MB received her CofA in the experimental armature built category only days before your photo was taken. I currently have 8.5 hours on her and am awaiting better weather to complete the 40 hr phase one flight tests."
