I couldn't have said it better myself.

My personal opinion, I'm not a big fan of PCM. If my heli has a glitch I want to know about it, I don't want PCM to cover it up until it's to late. If your heli goes into failsafe you have no chance of saving it. If you just have a glitch and you see it, you get your heli on the ground and find the problem.
A lot of people like using PCM, I'm just not one of them. I have PCM on my 90 but I have it disabled.
