I just bought the -8. Will the Quark 33a work?

Or do I need a 45a ESC?

got the scorpion 8 today.. put the new female plugs on it.. installed it (yes, I had to dremel out the holes for the screws.. no biggie)... reset the pitch curve to plus minus 11.. took it to the field....

Now, the motor works great.. LOADS of torque.. I've had to tone down the pitch curve.. adjust my pitch curve (stunt 1) to 95, 90, 95 to keep control of the tail when I give it full collective (the tail would yaw to the right hard).. I adjusted the gain to about 90... it works but had to bring the blade pitch to 9 on both sides.. when the batt gets about 3 min on it I see the same problem.. tail goes to the right when I'm aggresive on the collective ...

Any ideas?
