Quark 80B

[BrianG]

The 80B is actually less than a MM current-wise. The 125B uses the same number and type of FETs as the original MM, so I would say the 80B is somewhat closer to a Sidewinder. The only advantage to the Quark is that it runs 5s prefectly fine.

As far as smoothness is concerned, a CC ESC with the newer firmware is very close, if not better, than the Quark.

Like people have said; if you have the Quark, use it. But if you are looking to buy an ESC, I would go with a MM or something similar. And I just happen to have a NIB MM sitting around.
