Re: [Paparazzi-devel] Strange Surging Behavior

[John Burt]

Are you driving the servos and/or radio modem from the AP's power supply? If so 
then you are very likely overloading the PS and crashing the AP. Try powering 
all servos and modem using a separate power supply (such as a standard RC BEC). 
For good measure, you might wrap wires going into the AP in RF chokes. That has 
help prevent jittering for me.
