It's quite destructive and it's created in 30 minutes :D
Only problem is that it's wheels slide through arena :/

Feel free to make a showcase, but you don't get to post a thread for every single bot you make. That's not what general discussion is for.

Also, unless that Ztek is just reskinned, I would recommend stepping away from custom (downloaded) components if you actually want to be taken seriously.
