	A nice solution for e.g. Tiny and TWOG autopilot boards is use modern DSM and your trusty based autopilot board with the CPPM inputoption. This works as well on LPC and STM based boards. Note that for a configuration radio file on should choose an own one '''not spektrum''' regardless that the connection is over DSM the pulses are PPM out not the serial DSM.

	If you have no Spektum RX in connection on your autopilot board, a handy solution is to use a Spektrum receiver which outputs a s-Bus datastream. Orange brand has various receivers that have this feature.

	The wildly popular Spektrum and other brands of receivers using the spectrum protocol are widely available. Below a few of the tested ones. It is very likly others will also work well with Paparazzi, the only diffrence is, we did not thest them yet. Best of all the protocol is well reverse engineered and almost all details are known and implemented in various opensource libraries.

			The connector used in the Spektrum Sat receivers is JST part number S3B0ZR(LF)(SN) (Digikey part 455016700ND). This mates to part JST ZHR03 (Digikey 455011600ND). On the autopilot side various connector can be expected. On the Lisa type of board, Molex Picoblade.

	OrangeRx R410X DSMX compatible 4Ch with '''6 Channels''' PWM/CPPM out. This is the prefered modern alternative if you are looking to replace your "Classic" 35/36/40/41/72mHz receivers PWM/CPPM out for a robust DSMX receiver at almost no cost. Last time we looked the receivers where sold for about 8 Euro (~ 10 USD)		OrangeRx R410X DSMX compatible 4Ch with '''6 Channels''' PWM/CPPM out.

Last time we looked the receivers where sold for about 8 Euro (~ 10 USD)

			In order to use the receiver, failsafe has to be deactivated so the AP can detect the loss of signal (the rx still outputs PPM-frames if you don't). To deactivate it you have to give full thottle and also give full trim. Then you have to (re-)bind the rx. Check carefully if the GCS displays NONE if you switch of the tx.

			====Failsafe====

			To properly get the LOST bit when the S.bus receiver is out of range a hack for lpc21 is to use the led signal of the receiver (if the color is changed/tuned off when the signal is lost) and put this to a GPIO input. Then define some parameters to turn this into RC_LOST signal.

			See sw/airborne/arch/lpc21/subsystems/radio_control/ppm_arch.h:54
			And for the airframe (for pin P0.17):

			The word radio here is a RC Transmitter (TX), nothing to do with a device to liten to your favorite music channel. Opensource enthousiasts as we are, there are also various opensource based RC transmiitter for even more flexibility.
			We won't advise of specific brand here, the only keyword here is reliability. For 100% autonomous flight one could argue, no RC transmitter is needed. That is true, but experience shows that it is better to have a backup control device.
