An issue with un-sensored brushless motors is that they don't really reverse very well, at least not at low RPM's. For me this is an issue. This http://www.etotheipiplusone.net/?p=2373 explains the issue better than I ever could.
Of course you could add sensors and use the controllers discussed in the blog for what appears to be a viable control option for cheap R/C outrunners.
