Ye thats why i was saying we would like to try encourage people to have an active weapon, makes for more interesting fights. But its not an enforced rule. My fave robot from robot wars was storm II. That didnt need the lifter. Id rather watch storm II fight without the lifter than watch alot of the other robots with flippers and the pathetic spinning weapons alot of them had etc.
If sombody makes an impressive box it will make a more exciting fight than just 2 robots with average weapons fighting.

Flame Pit/Grill is sounding good (you can pick the melted plastic off the arena floor tho )
