I'll buy that. You're probably right about the signal pin not being used for high current draw, but I'm not sure how much that signal pin draws, either. Could you surmise why is it more susceptible to resets when the battery voltage drops from 5.45 down to 5.10? When you say "more filtering," do you mean "at least some filtering"? :) I have none anywhere, really, except for a bypass cap on the power/gnd PIC pins. The servo power/gnd pins are shared with the receiver's power supply pins. I'm kind of "branching off" of the line from the receiver to the servo.
