Thanks everyone for your help!
I'm thinking we will use the ammo boxes for the electronics and the pelican boxes for the batteries. Any holes Ill cover over with Sugru. To shoot, nerfballs, and cover the whole thing in lexan. And also I think we will use tamper proof screws so that no-one can unscrew anything.
Do you know if the RC receivers have the right pulse width to Jaguars or Victors? Also does anyone have any experience with tamper proof screws/bolts?
