That's awesome that you put my video to good use. For a second i thought that was the arm i made! You did an amazing job congrats! Right now im working on a new arc reactor design thats easy to put together but still look like the real prop then im going to make a tutorial for everyone, unfortunately the arm was to complicated to list out. Again great job try using white El wire to run to the arc reactor looks like power being transferred to the arm.
Your video was totally my inspiration! Awesome job!
