In the past Ive always used BB fishing weights, which worked quite well, covered in a dame of hot glue. 1/2" FBR, cut into 3" strips, with a little hole burned in the top with a hot glue gun. Drop a BB in the hole and cover it in glue, then put it face-up to dry.
That paintjob is wicked. How hard is it to figure out which pin to pull in the middle of battle though? Insane mod but It would just make me confused (and more than I usually am)
Very nicely done. I actually made something like this about a year ago. Not as well done as yours but the same basic Idea. I gooped a toy chainsaw to a minimized LS. I didnt mess around with the electrical components, and it wasnt a very good paintjob, but it was pretty cool
