Re: [Paparazzi-devel] FrSKY Radios

I also read about the low baud rate limitation. With paparazzi, you could 
configure a low baud rate telemetry message to suit the data link. Not ideal 
in every case but, on a micro UAV, you could save the weight and power 
consumption of the PPM encoder and xbee with a single FrSKY receiver.
