RE: Head speed and stability issues
PIlot... If you are using using a programmable radio, you can do all that stuff in the Tx as opposed to messing with the blade grip links. Right before I sold my Axe I was at the hobby shop and there was a guy there with a Dx6 setup to fly his Axe. He let me fly it and it was nice!!
If you are still flying with the stock radio, then I guess you don't have much of a choice....
