    My Motion Simulator:
    2DOF, SCN6
    Hi all, anyone out there knowledgeable with SCN6's?

    I took a punt on a really really cheap pair of 6's a couple of years ago, one is a 20-100 and the other is a 40-100. I think the guy was using the weaker 20 as a traction loss and the 40 for something else, anyway I thought for the money even though they're mismatched i'll see if they'll work as a 2 front post design. So I managed to balance the rig pretty well to keep as much weight off them as possible hey presto it worked great!

    So everything has been cool up until the other day I haven't touched them and I've really enjoyed the motion, then I noticed when testing, the 20 is lagging far behind the speed of the 40, whereas it wasn't before. So I figure fine, I'm not surprised it's weaker and so has been under more stress the last couple of years. So I ordered a brand new 40 to match the existing instead.

    Tested them again today and the 20 is back up again, responsive as ever. What gives? Now last time I tested it was after a 2hr race session, whereas this time it was from 'cold' so to speak. I felt them after the long session and neither were hot or even warm to the touch, so I'm thinking maybe it's the controller box thing that's on the way out? Or perhaps the 20 just needs a good service and regrease?

    Anyone know what the issue may be?

    Thanks in advance
