How much are you willing to pay for New Quark Monster ESC if they make one.

[GriffinRU]

I will by Quark, just because it is different for around half the price of 125B, because IC's now days are getting cheaper and they already good for CE and RoHS.

As for design flaws, I can pass them couple thoughts if they contact. But in general I am not happy with pcb layout they have, from heat transfer stand point. Enclosure (case) can be improved but pcb is the culprit. Also, make it water proof, so simple with silicon wires...
