Thanks for the help! I can definitely see where I went wrong in my design, from the ankle joint to the mechanism I'm planning on using to secure the shoes to the boards and my feet. I have some wood screws I can definitely use to secure the shoes to the board, and some 1"x12" rubber bands I can braid together to act as a tendon, to help with muscular soreness in my calves. Now my main concern is how long my stilts are gonna be though. I'm making ones almost 1 1/2 feet long, which would add another foot to my height and in the video he only made ones that added about half that length. Good thing I'm in somewhat decent shape outside of being skinny fat, otherwise I might just toss this idea out the window. Now to worry about the tail, wings, suit, and helmet. For the tail, should I rig up some kind of cable mechanism, or just let ye olde gravity do the trick with some weights?
