Ideal Wing fold is a 10 minute one person job. Road ability is secondary to the ability to slot in and share a scarce commodity of hanger space. I have plans for FRED which is what Scott Perkins terms a compound fold. Leading edge points to the ground and wing folds parallel to the fuselage. I have attached a few pictures of a FP101 with a custom semi compound arrangement. This has an advantage over a kitfox swing back wing in that you do not need the complexity removing the rear cabin and of flaps to swing up when folding along side the cabin. Balancing the need to keep it simple robust and not add much to the empty weight is where the sharp pencil is needed. Please share your designs on this thread for educational use. The 101 in the pictures was built in the early 80's in Wisconsin. The Snap shots are all I have I did not build it. It appears to add a second V to pivot the wing. The Pictures do not provide enough detail.
