^^ Richard, that is an amazing function. It's great that you are sharing so much information with us.
ericson, here is another video. A gentleman in Italy stringing on a 5502. Although the video is made to be funny, and one can't really see the 5502 in action.
Perhaps Mr. Parnell one day will be kind enough to share some of his photos/vids of his 5502 or even 3502.
