yes i still have the y..... and again i have to say....same set-up on my extra 330 and it works great....so to me the y is not the prob.
The Y is the problem! You may be able to get away with it on a different airplane but not for long. Think of the airplane as a room. I think that we will agree that sterio equipment will sound differently in different rooms. We would say that the " acustics " is different. The same thing happens with radio waves. Some airplanes have more or less materials that like to reflect RF. Some airplanes, just the interior shape can effect how the radio signal can be reflected.
So back to the issue, get rid of the Y and set up the ailerons with the dual aileron servo mix located in the wing function of your TX. Not only will you loose your current issue, but for once you will be abke to adjust your ailerons so you have equal throws. Equal throws are practically impossible with a Y.
