I really need some info on this. I've been experimenting but I have no proven facts.--Weasel 14:18, 16 June 2008 (CDT)
With some testing that I've done, I've managed to get down it works similar to the new joint mechanism, in that it needs to have 2 CFrames and 2 attached Parts to work properly. It's a little more complicated than that, but that's why I'm doing more testing. ---Mr Doom Bringer 14:35, 12 June 2008 (CDT)
I understand that they are like another snap, and they rotate much like real life servos. I can't quite understand how to decide the cframes and what goes with what. They are really useful though.--Weasel 14:18, 16 June 2008 (CDT)
