Question, what is this PPM port on the HobbyKing 6 channel receiver that people are unhappy that it no longer works? ......what is it for and do I need it?

Many Thanks,

Dave W.

simple answer: PPM caries all the channels on one wire

The RX sends each servo a pulse of varying width (time) to which it responds by moving to the appropriate position.

The traditional way of sending this information was for the transmitter to send a frame of pulses containing a number of pulses of fixed width but variable intervals between them followed by a synchronisation pause /pulse.

The receiver had a decoder that reset during the sync pulse and when the first pulse interval came it was routed to the first servo the second to the second etc up to the total number of transmitted pulses / channels.

This stream of information, pulse position modulation, is called this because the pulse that divides the information is of uniform voltage and time duration and it is the time between the pulses that carries the information.

This output from the hobbyking RX could be used to output the pulse stream for use in buddy box and PC simulator input.
Hope this helps

Thanks Bill,
I thought I was missing out on something I needed, never used a buddy box in 40 years of flying RC and not that interested in sims either. Thanks again.
