This is my bird It's a little rough around the edges,but flies well .Empty weight is about 220lbs
These are the stock  9.5 hp Rotax engines, each direct driving two,  28" carbon filled nylon propellers stacked on top of each other.

Despite this inefficient configuration, the plane proforms quite well

Tha Lazair even goes on floats

 This is how far the Lazair evolved, before the demise, What a beautifully sculpted enclosure.I love to get my hand on one of these.
