Boris,

Obviously there are several reasons = for a heavy wing and several solutions. One, as Gerard notes, is flap = position, that is the flaps are differently deployed.

The fuselage flap fairing positions = before “adjustment” are a bit rough on the 300 series but can be = "tuned". By that I mean the fairings are not at an equal level condition (WL) = with respect to each other from the factory … at least mine = weren’t. You must make them equal in waterline position by “adjusting” = the fairings during construction (heatgun and urging). Otherwise, one WILL = be at a higher (or lower) WL than the other.

So we’ll either suffer the = indignity of having flaps that do not match with the fairings, your reflex will = not be perfect, you’ll fly with offset (un-faired) aileron to fly with = out roll, or you’ll split the flaps and your ailerons will look funny when = faired with the tips. Or a combination of some of these.

Bottom line, if your flaps are not = at the same WL at the fuselage fairing nor faired at the level position of the ailerons --- all at the same time (assuming no twist in the wing), one = wing will be heavy. Splitting the flaps (one slightly up, the other slightly = down) is one way to solve this. There are others as above.

Boris, for fixing the wing down problem I would also check your = flap alignment-if both flaps are not retracting equally it will fly one wing = down. This also makes for interesting take offs with 10deg flap set especially = with a X wind
