That's got to help the blow back a heap giving the servo more mechanical torque over the aileron horn.
Should help, also at this point you should be able to dial it down a little more at a time without sacrificing too much resolution just by adjusting your rate. This way you can get it to the point of max deflection before any blowback just with radio adjustment to see if a lower rate helps. Once you find that point then you can adjust the mechanical connection to regain all your resolution. It's kind of a slow process but once it's done, it works so nice. This is the process I use on all my planes for all the surfaces doing one control surface @ a time. On most of my planes it usually takes about 40-50 flights to really get them dialed in, but once you find that sweet spot it just makes flying so much more enjoyable and almost effortless.
