Depends how much power and noise you're willing for it to make!!
replyRemember that texas instruments DLP technology which is in use in pretty much every office/home cinema projector is effectively micro flip-dots micromachined in silicon, and that can operate at ~10,000 FPS.
With my rudimentary physics knowledge I'd think that smaller structures can be moved faster than bigger structures.
replyEDIT: also when you google a bit you can find a guy who maxed out flip dot displays at 30fps (which honestly I thought would not be possible either)
Uhm yeah they are a lot smaller. That makes a difference obviously.
