Hi 5ash , as far as I know all Vixen GP clones will fit the same duel axis drives that are made and marketed by several different companies .
You have to be careful of the Dec motor as its very exposed on these and easily broken , I made a cover to fit over the dec motor I had on my now sold EQ5 and if you want a few photos of how I done it you only have to ask and I will send a few .
Brian.
