Nice! I'm quietly trying to make the move over to brushless too. Bought some for my next featherweight and I'm looking into heavyweight weapon drives - if Ellis with Pulsar, and the Big Nipper team can get them working well, then hopefully so can I.

I do like the Battlebots style, it feels like a fresh approach with a lot of diversity. Admittedly a lot of BB teams have much more funding than us, but I definitely feel there's a place in Robot Wars for lighter-armoured, fast aggressive machines, as we've seen recently to some extent. All the best with your brushless endeavours!
