I was taking issue with an oversimplification, one you made for the sake of convenience, I'm sure. Pet peeve of mine. In an earlier thread on slips, I asked whether anyone had thought through the notion of using a slip (dihedral rolling moment)to counteract the overbanking tendency . I didn't note any responses, though it might prove interesting to develop the idea in the context of this thread. I think experienced contest pilots have been doing this for a long time; in '74 in Oz, I found in the first practice days that the Std Cirrus was outclimbing my Libelle quite depressingly; I was used to flying string in the middle. First action, was to get the CG on the aft limit with lead; removed the tail down force and the control surface drag; then to counter the sprial instability and keep the flow attached at the inner wing root, I used slip and was able to leave the ailerons nearly neutral; climbed with the Cirrus just fine and when they had full water, i could go up the inside. winglets now change the whole thing; you must keep the string in the middle or one winglet stalls. John Firth Old but no longer bold pilot. Dodging the math, I'll also add that a few extra knots while circling gives a great deal more aileron and rudder authority. Since smooth, elevator cores are the exception rather than the rule, the more effective your controls, the quicker you can correct for or take advantage of turbulence, then get the controls streamlined (or as close a practical) to minimize drag. The lower the speed, the greater the drag for a given control input, and the longer you'll have to leave it in to achieve the desired change in direction.
