The servo signal is transmitter generally in a form where the pulses for each individual servo are sent through the radio waves as one signal that contains every pulse after each other (and some sync information to know when first servo signal starts). So I quess that in this kind of system a simple receiver would send the received pulses as they arrive (each connected to their own output, in oder they arrive). So it is most propably that those pulses start at different times (each on their own timeslot). -- Tomi Engdahl (http://www.iki.fi/then/) Take a look at my electronics web links and documents at http://www.epanorama.net/
