[Yogscast]

I am mostly talking about how Duncan has the crafting table 3 and electrical engines. I want to know what update he is using so I have the items.

I have recently been watching the yogscast and their tekkit series, but some of the items they have I can't get. I was wondering what update they use when recording. can anyone tell me?
