When looking for some e-sky and blade motor listings, I came across these:
Their specs are quite superior in terms of 2s lipos, drawing 0.75A continuos each while blades would draw ~0.6. The RPM on these would be hitting the 40k mark while blades would hit ~28k. For 3s, I still think blades would be better but these seem to be better on 2s. In terms of price, these are about $3 a piece which seems to be a bit cheaper!
Since these are 180's, their inertia and torque should be substantially higher than that of 130's. These are in fact, carbon brush so there is no need for getting all worried about stuff like: "Am I going to burn out these motors?". For those of you who aren't familier with what carbon brushes are, here's a photo:

So basically, the things on the left are parts of a standard metal brush motor. the brushes which are the things at the top are very thin. The problem with that is that you will be sparking these brushes all the time whenever you put power into the motor. That brush will get worn down as heck! Now look at the things on the right. Those are the parts of a carbon brush motor. Look at its brush set at the top. It has two chunks of weird things right? Well those weird things are what makes carbon brushes carbon brushes. They are chunks of carbon that help with brush wear.
