Really keen to hear your ultimate findings Paul. My G-11 was delivered with Gemini and until what I ordered (standard Digital Drive & steppers) came through, I had the Gemini on loan. It was always stalling on me and I rapidly became tired of the "RA Stalled" messages I continuously got. I had the scope very well balanced in 3-D and the worm gap was perfect - not tight but no slop at all. It turned out that the RA servo was stuffed ex-factory, and the Dec servo was only marginally better because I did swap them as part of the diagnosis. This kind of fixed the problem, but on occasion it still stalled.
I eventually recieved the Digital Drive and replaced the troublesome servos with steppers and the simpler logic. Never had a problem since, and intend to add an ArgoNavis to it. I have found that the worm does need clearance maintenance periodically though.
