Hi Graham, thanks for the info. I was going to try it on an O'Connor in the test room on Tuesday. Problem is that we have very limited prep time as I'm on recce's, too. We start shooting in anger on Saturday and I'm in real trouble if it doesn't work... I have tried going significantly further away (20ft or so) and it still doesn't work. Could it be a stiffness thing, or perhaps an interference issue? I've tried it with the Movi controller and Alpha wheels on another rig and it was fantastic. My one may be a faulty one, i guess.
