Today while we were out I got same brass pipe to make K-9's ears. It is going to be tricky to get them to look right.
Also today I got R4's horseshoes together and mounted. Now I got to bondo the ends of everything just like R3's legs. I am really not liking the yellow on R4's boosters, It scratches off easily and is not uniform in color. I may strip them and try a different brand of spray paint.
