Looks pretty interesting. Don't know if you need more than one axis on stabilization though. Not sure zeroing it in with the DMD is gonna work either. Doesn't look very expensive though so I'd give it a try.
For now I'm going with the Alexadner Engel r/c sub pitch control for stabilization. It's quicker than the tamiya unit and cheaper. It's also plug and play and you can adjust sensativity.
