On my EF Yak I am using 10 degrees of elevator throw for IMAC. I've been flying with Kevin Miller (you should meet him on Sunday) and we've been steadily dialing down the throw on all of my control surfaces. My ailerons are still too "hot", but I will fix that next time I go out. I was amazed at how little control throw was needed to fly the Sportsman sequence. Kevin flew the Unlimited sequence on my IMAC condition with no trouble at all. I am finding that less throw with moderate expo 20-40% is working well for me.

I will be out of town on Sunday and will miss the Polar Bear contest. Good luck and I'm sure I will see you at another contest.
