mainly ebay, and a few other online stores,, just search 1/6th heads or bodies,, lots of options.. the epoxy sculpts are smooth-on products (standard and light-weight) kind of a slow process of a layer a day, best if you can work on several at a time.. other fine details I'm using sculpey polimer clay that you bake to harden.. to further the maddness I've cast a fiber glass torso with the hopes of mounting servos to work the arms,, control for throttle and fwd/rev... I'm holding off on final sanding and painting until all the figures are at that stage..
