I was there when it happend and Geoff was never in any sort of danger. It does scare the pants of you if a Tanto Jr. comes smashing into your polycarb but that is what the polycarb is there for.
I don't see how this rule can be enforced though, if a 3 way cluster registers with 3 33kg cluster parts they are in fact a 99kg robot.
Leo, they wont let Maxus and Voodoo in as a clusterbot with the heavies and their combined weight is about 80kg. Maybe its something that needs to be brought up with the FRA. I've tried on the forum but haven't had any response.
Oliver might remember this, but didn't we have a discussion WAY back when the Tinweb forum was up about building a heavy cluster called SWARM - 7 clusters as I recall....
