I just recently finished modifying my glidecam. Top stage can move up or down so you can find the balance. My first one was flycam 5000, it was a piece of sheit and a month or so later found Glidecam HD 4000, like it, then went crazy after purchasing my friend steadicam arm and vest. Lots of research and finding machine shop to help. Oh and didnt cost me extra on the machine shop, good to have friends who are engineers .
Test I did, it's ok, now it learning to operate it better...sorry for the epic music..lol
