I was also thinking. This could also just be an issue with the 5945 servo. I can only get it to happen with a 5945 and not my 5645. Seems to match joes claim of it only happened on one of his airplanes and not the one with the 56xx servos.
Hilleyja. I think that your problem could be battery related. I just got educated by the owner of NoBS batteries on internal impendance (sp?). The digital servos could be loading the batteries too much and the voltage maybe dropping too much causing the glitch. Just a guess. Trying to explain that side as it disproves my 127 theory.
