    Sounds like it'd be cheaper to just buy 20mm bar stock and have someone mill a keyway into it.

    Selling a couple of things I used (and some I didn't use) in my beetleweight DHM, which ended up being a bit of a flop and only had two fights. Parts are fine though, there's no damage and they're...

    Hey guys, my second robot's driver is sorted now, and I've emailed James. I was heavily considering Jamie's advice of just dropping the second bot out to let someone else in, but since this person...

    I did think I'd just grab someone, but when I emailed James about it, he said I needed names in advance, that's the thing. I have a friend who would be able to for Saturday, Sunday and Monday, but...

    If they're the typical 1000RPM 12V gearmotors, they'll be brushed. I'd recommend Rory Mangles' BeetleTwo. It's a dual channel Speed controller so you only need one for both wheels. For that you're...

    It was £25 for me. I'll probably show up with both bots regardless, even if one doesn't get a run in the competition. Still though, I might email James to ask.
