Full Version: XJT-D16 versus PPM latency

Jim,

I was thinking about the latency in my RC systems.

I believe that my Futaba 9C transmitter delivers a new set of channel positions by way of PPM to the XPS transmitter module every 22,5 millisecinds.

Using the XJT-D16 protocol the Taranis delivers a new set of channel positions to the XPS JR-type module every 18 milliseconds.

This means I gain about 4.5 milliseconds using XJT-D16.

If I happened to be using all 16 channels I would be about twice as fast with XJT-D16 than I would be with PPM.

Is that correct?

Thanks,

Paul
Yes, that is correct.  However, a human is not able to discern latency differences below about 25ms.
