I don't have any advise on where to find a wing but I had the 72 inch version. I set the aileron throws as directed plus some more. I also had dual rates set in. The plane flies great and is very gentle. If you find another wing, I would suggest setting up dual rates (one with large throws and one one with low throws). If the plane is twitchy, go with lower throws. You might also check the cg. Mine was a little nose heavy (OS 90 four stroke in the 72 inch version).
