I built these mini mechs several years ago after one of my friends showed me a concept of a small minifigure sized mech. To build these, I used pieces from the Rahaga and Atlantis diver helmets, plus other pieces. I also made them so they combine into one giant mech and a snow mobile of sorts.
My only real problems are individual color schemes and the overall color sceme. The colors make them look thrown together. outher than that they’re gr8!
