Hi Bill,
The GM811G is just a G11G bottom with a GM8 top. So the tracking will be just as good if not better than the G11G because the RA axis does all the work once you are on an object and the G11G base is more than capable of carrying a 60lb. payload and in this application Losmandy has underrated the drive to fit a spot in the new mount lineup.?
Chip?
