RE: futaba 9c conversion to 2.4
I almost kept my synth module for my 9C, and bought a synth PCM rx, just in case for some reason the 2.4 didn't work somewhere. But in the end I sold all the 72mz stuff simply because I was worried about forgetting to get a freq pin if I ever did use the 72mz, or being shot down by some park flyer. In addition to the TM-8 and 2 608 rx's, I now have some peace of mind.
