Dear Netters, Some months ago, some kind and knowledgeable soul posted a brief description of the signal that one of those remote control airplane engine throttle servos expects. I recall that it was some odd kind of pulse width modulation, but little more. Does anyone still have that post, and if so, could you repost? Oh, I would also like to know what color coding of each of the wires means, if this is standard. Thank you very much, Jim

Usually red is power supply (4 to 6 volts or so), black is ground, and white is the PWM signal. Send mail for more info, but that should be enough to make them work.
