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....
