Claude,

This is a self design called a Lighting by the gentlemen in the picture, Jeff Carder. He competed with it in the 2007 US Nationals in Masters placing 4th. As I recall he combined design elements from 3 different aircraft's, Partner, Brio and Twister. The finished aircraft is absolutely beautiful and is an engineering marvel. Truly outstanding.

Jeff is a F-16 pilot by profession an is currently overseas and is a RCU surfer. Perhaps he'll see your post and provide more details.

There's a picture of him with the aircraft at the following link on page #5
