	RC transmitters generate a pulse-~~pause~~-modulation PPM signal from the angles. The information is in the length of a pulse. Usually a 1.5ms pulse is middle position and 1ms equals -100% and 2ms 100%. The pulses are sent as a packet and repeat at about 15ms rate The following shows a 9 channel transmitter (this is 10 pulses) and a decoded servo #1. Use RC_FUTABA in your airframe conf file if you see a signal like this (pulses go "high").		RC transmitters generate a pulse-position-modulation (PPM) signal from the angles.

	Note: Proprietary PCM is not supported directly by Paparazzi at this moment. Ofcourse if one knows or reversed the specific PCMx format one can add support to handle this format also. However it has no direct benefit for the autopilot project.		Note: Proprietary PCM is not supported directly by Paparazzi at this moment.
