Hey Scott I'd like to put my 2 cents in as well. It's very easy to loop a heli on the sim, yes. It's also very easy to loop a heli in real life it it has a good gyro to keep the tail straight. I found with the Blade that when I used a lot of +pitch to go into the loop that the tail would shoot 90 degrees and as it went inverted I added -pitch it made it even worse. At that point your flying out of a crash not making a pretty loop. If your CP+ holds well then just do it, I was surprised how much my fear held me back to find out later how easy something is. Like Jer said, do it will good altitude, in good sight , and good orientation.

Best of Luck and God Bless!
