Ozzieflyer,

Firstly, I thought I gave you a significant reason why you should use PCM in Post 25 but you didn't respond to it? Personally I would ban PPM on models above 40 size if I could on this basis alone. If it saves just one life or serious injury it would be worth it.
Secondly, I'm not sure how you can read the links to the excellent reports indicated by Keithb and not be convinced as to the value of PCM.
Thirdly, PCM do come out of failsafe (as per the report) once the interference is removed.

You can always find someone with a contrary view on anything, in this case there are some great reasons for going to PCM that outweigh the value of PPM in the case that interference keeps a PCM Tx locked out for long enough for the aircraft to crash.
