i say... thats... well.. yeah a medium ranged spuddy.... because the only visiable difference between mine and yours is the regulated fuel system. Mine is a 4"Dia X50cm combust with a 2.5" barrel for tennis balls... and i have a small hole which i use butane cans to fuel my cannon... Activated by a ...
