And I have just started changing over slowly to my Hitec 2.4 system. When speaking of 72 then PCM is way better then PPM but 2.4 is better then PCM. I have sometime set up my gassers using standard PPC, when I got the plane set up for glitch/RF free operation then I would install a PCM. Flip side of that was sometimes I couldn't get it glitch free so I have given up and gone to PCM and it cured my problems. 2.4 is a lot better but there is no truly perfect system, 2.4 is just as close as we have ever had it.
I am in need of a 9ch Hitec 2.4 RX right now so I will be test flying my new plane with PCM until I can afford the new 9ch. I have never had any problems with PCM but I don't want to be risking getting shot down by someone else with this new plane so I will change over as soon as I can.
