T3's neck works ok for a while but ends up coming loose or binding after a while every time I use him. The same thing happens for his rear legs. I am going back to redesign them both for more long term, heavy duty use. Got to love prototyping :P Everything should be working 100% for CV.
Doing the final painting on R2-CM is at a stand still till the weather warms up.
His periscope works fine now but is still way to heavy. So now I am going to make a new one out of lighter materials. I will retrofit the old one for some lower body gadget maybe.
