[Paparazzi-devel] Reply to:"Question regarding servo motor (Steffen Spies)"

Is the modem active at the same time?
I used to have jitter that would go and come back again at random and 
the culprit was
the 9xtNbd modem (900Mhz).
Actually the modem is not the guilty part, servos that have poor 
filtering are or in your case the rc receiver might be problematic also.
Some servos are prone to this and some others are not.
For example the Hyperion ATLAS DS20x is behaving like crazy when the 
modem is active but the
DS20 (not X) is totally immune to 900Mhz noise.
