I am new to this but found these a while ago and wondered if any of you had any experience with building one. They look good in theory but makeing a plane and then putting yourself in it and actually flying well lets just say i am not that good of a metal worker or fabricator yet. Or at least i dont feel that I am and if I dont feel it then i am not goin got try it. The sight that I originally found was where someone was casting the rotary engine that he was building for the F4 UA which i have always wanted to fly.

This is the sight for the plans and this is the sight for person casting the engine http://warbuddies.homestead.com/JimsFoundry.html
I would love to see or hear if you have any ideas or experience in this would love to see one of these in real life although flying it might not be ready for that yet. Even if it would sound very exciting..
