The opposite takes place in airplanes with counterotating engines. The more flaps you have the higher VMCA will be...draw you a pic and think about it.

I understand the first part but can someone please explain why it would be opposite on counter rotating? The counter rotating suffers from P factor too, maybe Im not drawing this pic right.
