    agree, let the front edge scrape along the floor. You may even want to try determin the angle to cut the side wedges too so they run as close as to the floor as you can calculate - i tried tat but...

    Just let the front scrape. Not only will it make it easier to get under opponents and save weight, but it will also help dampen the steering/control slightly, as sometimes having a really...

    I used to use ball castors in The Honey Badger and they never lasted. I find that off the shelf things like that tend not to in the arena.

    I really enjoyed big Chompalot on RW. Look forward to seeing the mini version, the CAD looks great. Should it be called Chompalittle?
