I was interested in the Hitec HS 60 Super Micro, but the GWS seems to be cheaper, smaller, higher in torque output, and has a ball bearing. Please take a look the link provided above and see for yourself, may be you'd like it too.
Regarding my ESC choice...I think the Race-20 is smaller and lighter than the SPY, but I could be wrong though. And there is a chance that I will get a RS4 Micro and run it with more cells and a more demanding motor than the SPY can handle. So it seems like the Race-20 can do better (and is cheaper too) than the SPY except for the missing reverse function, which I'm used to not having anyway. And I did look into the SPY and actually liked the overall design and quality a lot, so I may as well get one to replace the Race-20 on the ABC SP after the Race-20 into my future RS4 Micro.
Anyway, thanks for the recommendation.
