First Tom Moore of Kinston, N.C. designed the Vertigo and made several changes in the plane to inprove performance. I have a nib kit of the Vertigo two made by Skyglass. Tom is a good friend of mine he went to work for Bob Reuther who owned Hobby World in Tennesse. The last time I saw Tom fly was at the World Championships meet in 1988 at Virgina Beach. I have lots of pictures of Toms plane if you are interested also I know all the mods that Tom did to his last plane. If you are interested in a Vertigo two kit I would sell mine.
