Same here I have been flying FM for a very long time now and not once have i been shot down. I have been hit but that was corrected when I yelled out, the guy then cut his transmitter off.

I guess the one of the reasons I have not swapped to PCM is because my FM is still working fine for me. I have used this radio for helicopters, sailplanes, small planes, .90 size planes, extremely fast planes and now bigger 50cc gas.

If I had to buy a new radio gear I would maybe go with PCM just t have it though i guess. Just I haven't not had to buy so thats why I am still using FM.

Either one you go with I think you will be okay and cant really go wrong.

One thing u mentioned that your club members strongly recommend for 3D and larger airplanes. The larger ones i heard people say that before due to ignition issues or vibrations. But I wonder why they strongly recommend for 3D? 3D planes still fly the same as the others.
