Hi Everyone, sorry for being so slow getting 3.8 out. It is still just that I haven't had time to do the documentation for the large changes in servo config in 3.8.
I suspect this is a GCS issue. The parameter has changed from RCn_REV to SERVOn_REVERSED and it is now 1 for reversed and 0 for not reversed. There is some work needed in the GCS user interfaces to cope with this change.
