The ES-100 is the first produced exo-skeleton in the UNE. Unlike the MCF series, the ESs fit more like armor than a machine you step in to. Made from 3" thick titanium, the legs are hydraulically powered and meant to withstand the impact of the half tonne suit. However, as with all new technology, there are problems to be worked out. The arms have a rather limited range of movement.
I hade made this flamethrower and thought,"well, this sucks, it's too big for a minifig." It just kinda sat in the basement for a while untill I thought about giving this thing a weapon. It's the perfect size and color.(or at least I think so)
It doesn't look all that great from the front of back, but I'm getting better.
