The Sportsman beetles are normal beetleweights, but they can't have metal spinning weapons because our arena can't take it.  We are allowing conversions of spinning weapons to any plastic available.  They can be printed, UHMW, Carbon Fiber, and any other non-metal you can think of.  you could even make it out of wood if you like.  For our event currently, the beetles are there to show the bigger side of local robot combat, but still being safe with our arena not able to contain the full power of beetles yet.
