Are the hobbwing motors any good?

Which one of your many vehicles are you looking to power?

I was just wondering if they were worth a crap... Looking at the fact they have an integrated fan mount would lead me to believe that they are not the most efficient motors on the planet. I doubt that I would buy the HW80 and motor combo, as cheap as they are I can usually find deals on lightly used equipment that is much better...

So I guess the question was more for academic purposes than anything else.
