So, from what you have seen already stu, will you let this weapon run at the FW smash?
I run the weapon in a part of my my back garden, which has a concrete floor. When operating it, I put all the switches on etc, and I go to the second floor of my house, I look out (airiel stcking out window) and operate the bot from there. This is as safe as you can get when testing...
I will never run a weapon like this at close range, or in an arena incapable of containing it.
