A toy robot? Good luck to them, I hope they've got some brains for it though. I build a smart datapad with automated arms but I make a little error and almost lost my nose!
I'll take a look at the tailgun, if it's a seventh-gen plascannon, it's probably got a warped heatsink. It's a standard model, not cheap, but damn if they don't use poor components. I'll see what I can do.
Name's Hake, by the way. Buxtable Hake. Low-level mechanic, but I have a lot of tutorials on the datapad!
