Thanks for the replies. I either going to go with the Futaba 7c or 9c depending on my budget. This radio system will all go in my second plane so that's why I'm asking PPM or PCM. I am aware that they can transmit in both PPM and PCM, but which radio system for my second plane? The 7C and 9C come with either a PPM receiver system or PCM system. I kind of worried about the PCM fail-safe. I don't like the idea of a plane flying on its own with no response for might be a few critical amount of seconds then again I like the idea that it sends out an exact signal.


Thanks a lot!
