The model will only go into failsafe as long as there is interference around. After the interference has ceased normal operation returns immediately. At least it does with JR and more than likely with other manufacturers as well.

Plus as PPM receivers aren't top of the range (correct me if I’m wrong) they don't come with all the other stuff the top end rx's do such as narrow band ceramic filters and all that gubbins.

I thought it was compulsory that models at shows had PCM and if it isn't then it bloody should be. You can’t argue that PCM is not far safer than PPM. When you go to competitions they check you have a failsafe i.e. that you have PCM. Should be the same at shows.
