This is just the first version of mech arms, but not the first made. I am trying to make my own products of industry instead of building off previous models. If I could rename my profile it'd be MECHATECH, but I can't. Anyways, the controls are again, wonky because it's just being tested, but here they are: Use the VTOL bar for all of them, VTOL group 1 is the rotation of the whole arm, VTOL group 2 is the wrist twisting, and VTOL group 3 is the wrist up and down. I put these all in groups for concentrated movement and selective controls. Anyways, this won't be much of an advancement, but it does add a little perks for your amazing mechs. Also, have fun with this way too simple mechanic and see you later!
