Move the CG back and also see if you can get a little more elevator throw (45-50 degrees).

While I don't know where the "sweet spot" is yet (I'm still dialing mine in) I have heard from other guys that go as much a 1 1/2 inches BEHIND the wing tube! (Found that one surprising the first time I heard it as well) I wouldn't jump to that point but slowly try moving the CG back. I was talking to Rocco at the TOC and he suggested to just add weight to the tail about an ounce at a time until when coming in for a landing slight elevator movements make the plane balloon.

Personally I think Tim's advise is the way to go and set the CG based on inverted flight. Nothing more unnerving than having to hold up elevator to sustain inverted flight.

Let us know how you make out..............Mark
