@Ocracoke, am Wirral based too . Seems there are quite a few teams in the local-ish area!
Nice, I am organising a meet up of the local(ish) roboteers for the 3rd of March if you fancy it (http://www.fightingrobots.co.uk/thre...l=1#post470829).

Personally, I am on the fence with having a smaller motor for driving the weapon. If the KV is a near enough match then I guess it would be OK.
