I have been flying a Still Stuka that has one annoying characteristic, as the wind comes up it wants to float up. Balance is at the 18% point ready to fly. Some have suggested that I need to adjust the elevator to flap relationship by adding a 1/2 turn of down trim. What trim adjustment will improve the tracking?
If this is just a sight tendency to rise into the wind I think that is fairly normal even on a well trimmed stunter. We (the nut on the handle) tends to more or less automatically compensate for that dendency. Now the rub...if the controls are not completely free and smooth around neutral there is a light hesitation in that compensation for very small inputs of the type that this requires to maintain level flight. So...question...are your control very free around neutral?
There is some validity in what Doc said also...if you are being forced to conciously hold some down (slight) in your handle setting to maintain level flight at 5 ft then the rise that occurs going into the wind will be more obvious because your response for correction will be slower.
In the event that your controls are very free then you might try adding a little down thrust in the engine or tweeking a little down into the elevator relative to the flaps. This may however introduce an uneven turn rate between inside and outside maneuvers. Since I've mentioned that are they even presently? More handle sensitivity in one direction than the other can cause a tendency toward the problem you mentiond also.
