This is interesting: Sky RC brushless motor checker

I was looking at that when they first came out a good while back. It never became popular. Is good for the small motors and meant for the racers to weed out their low performing motors. But it's useless now as, you can just up the timing, boost, turbo and whatnot within the esc for more power.

An Eagletree is a better value.
