From my limited understanding of the rc battle scene, the current meta is spinning kinetic weapons. Just get a hunk of metal spinning fast and go to town.

I do wish that there was a larger variety in designs and weaponry, but I'm not complaining about seeing shredded bot bits flying across the arena.

Even the Micro-bot scene is getting interesting as rc parts get cheaper and cheaper. The bar to enter is lowering daily. I'm thinking about ordering some things so my wife and I can have little driveway matches with flippers and grabbers. She wants a spinner but I don't want to break the bank buying replacement parts...
