Just wondering what kind of capacitor network have you guys found to be the most stable for a PIC micro controlled servo, both using shared power supplies?
What does a capacitor network have to do with a PIC generating servo signals? The only thing I can think you're asking is what kind of decoupling capacitors people use. If you can live with the diode drop to the PIC you can use a super cap or a large electrolytic on the VCC/GND lines so the PIC can drain the capacitor but the servo can't, that will give you the most stable voltage possible, especially when the battery pack is weak. Otherwise use as large an electrolytic as possible and a mid range tantalum and a smaller ceramic to try to filter out the noise the servo will feedback.

you pretty much summed it up - the current draw is so great that the PIC resets/doesnt seems to function correctly.
