Ah, yes. I will clarify. Spinners are not permitted at all events. Only those with Class 1 Arena's.

Since the only Class 1 arena's in the UK are the new Robot Wars arena in Glasgow (which we can't use) and the Robochallenge FW arena, which is only used twice a year at most, your robot would be limited to just 2 events a year: The World Champs at Gadget Show Live (which just happened) and possibly an event at Fleet Air Museum (which doesn't always happen).

The rules above 12.3 & 12.4, would still apply at the Class 1 arena events.

If you don't know what I am talking about, read the Rules and Safety Documents - http://www.fightingrobots.co.uk/cont...s-and-safety_1 - You may never run an event or need to know about stopping EM interference but its good stuff to know regardless.
