I'm sorry to say that Spectrum is not the "save all". I currently have a similar problem with my ailerons when I am running my Brisson 5.8. I have the JR9303 with spectrum AR9000 reciever. The problem is not through the Rx, but rather through the servo lead itself. My data log on my AR9000 shows very little frame loss and no fades but my ailerons are dancing like crazy. There are only two ways to approach it....try to kill the source of the RF noise or try to shield the aileron leads. Buying a spectrum system will not fix it.
