Tracon,

David is right. My problem was ballooning on final with throttle chop. The plane would sink fine until you chopped throttle, then whamo.....back up went the nose. This is certianly a thrust angle issue that will need to be corrected later, but here's what we did:

The first fix was to mix in some down elevator at just above idle. That worked fine, but on the last flight of testing on a Sunday afternoon, I lost a wheel in the air. The landing resulted in damage that would need to be fixed at home, so had to wait another week. Last week, we continued testing and I was going to start playing around with David Cutler's suggestion of adding a little "up" orientation in the ailerons by turning out the clevises, but was a little reluctant to trade airspeed if it turned out that way. So we dicided to try a landing mix. I have the JR 8103 that has a landing switch on it. This allows you to configure the plane for landing and activate the "landing configuration" while on final.

This was the ticket! 18 degrees of flaperon causes the Edge to sink at a comfortable and predictable rate. The plane now lands (if there is a little head wind) almost as slow as a LT40 and with no wind just a tad faster. There is very little wing rock as it slows down comming into ground effect. I feel much more confident with this set-up and can focus on enjoying the flight instead of dreading the landing.

Give it a try. Mixing is pretty cool.
