When using a 72mhz radio, is it best to use PPM or PCM with the APM? Thanks.

The APM won't see the difference if you are using servo PWM outputs.
The advantage of PCM is that is has failsafe capability. Some 72MHz PPM Rx's have failsafe too. The Corona and other synthesized ones do.
I guess I need more information on your equipment and objectives to answer your question.
Ultimately you will likely decide to move to a UHF system. Those of us who have been down the 72Mhz path have switched to a more interference resistant protocol.
