This is something I did one day last week while looking in my parts box. I remembered I had the hands left over from a movie 1 Prime and I remembered that I was trying to find some hands for Superion. I took the hands and dremmeled them off flat at the base and found two 5mm pegs and glued them onto the hands. The pegs fit into the bottom of the individual robot feet as shown. There is that hole in the bottom of the feet that the pegs will fit into perfectly. Make sure that the peg fits in the hole BEFORE gluing! This took me about 30 minutes and saved me a load of money by not having to buy the add on kit but at the same time gave me functional hands. Enjoy! Please comment!
Nicely done. I've been pondering on how to soup up my Superion too, and this is a good, simple solution.
