Our team did AM14U with Touhgbox Nanos last year. We did have some difficulties with poor tolerances in andymark machining and the lack of a tapped encoder mount, which, because of the poor machining, we were unable to easily remove and tap to add the encoder. It was a mess and very difficult to assemble, although it does, in theory, work. I would not recommend doing it. I'd recommend finding some other gearboxes or make your own.
