Questions about BL stuff.

I've only used the MM, BK 12020, and the Quark and like the Quark much better out of the three. Yes, it will heat up a bit, but strategic use of an added heatsink helps tremendously. Any heatsink will work - it just depends on your layout. I don't use fans and the temps are always good at ~130 at the very highest. As AAngel pointed out, they are silky smooth running. Cog free even at very low rpms even with a decent load like uphill or going over small obstacles. They can also run outrunners as well as inrunners (with a programming change)
