Some more progress this week. I've dismantled everything previously built and now have a box of bits, esc's, motors, batteries etc and am concentrating on one spinner-proof (I hope) robot.

The inner chassis is cut and only half bolted together at the minute, just to see if the wheel slides over with any clearance problems. I'm working on a heavily shock mounted chassis-shell mounting. I'm having a worry with self righting, I will dream up something for that.

I have a 22 lorry wheel on the way that I've bought to start building a heavy weight as well. For that I'm wondering if 6x Gimson's and a good speed controller will be enough. I'm going to work out the wattages, and failing that get a second hand wheel chair.

I'm umming and arring about weapons, I'd like the feather and the heavy to be similar in appearance and weaponry, colour scheme etc.
