    Flying Experimental Airplane Around The World

    I have a friend who is considering flying a EAB around the world. He has already reached the conceptual stage where he is mentally designing extended fuel tanks. This sounds like fun and I am (kinda) interested in joining in on the fun...however...lots and lots to think about. I already...

    50 years without complete overhaul

    10/23 Raptor Video

    I like the idea of the wings unbolting at the side of the fuselage. Why dont home built airplane designers do this more. Everyone will at some time need to trailer the airplane so this makes sense
