Zooland, you have it backwards there. Pitching the blade down by lenghtening the short link, is giving it more positive pitch, not negetive. This lowers the head speed and brings the blade up cause it grabs more air.
I didn't say "pitch it down", I said raise the low blade, which means you add positive pitch to the blade. But you're probably right in that it would grab more air and in turn lower the head speed. I've been trying to get an infrared tach to check my head speed so I missed that one. But anyway you still want to raise the low blade by adding positive.
