So I crashed the 550X a couple weeks back at the club field trying the top half of a half piro flip. Heli ended up between me and the staging area/fence. Luckily only a couple others there so no one got hit with it, including myself. I'd feel bad about it except I started the attempt a ways out from me and about 50+ ft up. Pretty safe. Or so I thought. 
I've also crashed the 300X a few times now trying the maneuver.
So I went back to sim practice on it for a week or two and decided to give it a try again at the club field last evening. This time I had an audience.
And I pulled it off!
They still need work, but they are far better controlled. I complete to a tail in hover on about half of the attempts. 10% I screw up the start of them and end up just wobbling around a bit. 25% I get to near inverted hover, but the tail is 30 degrees short of tail in (need to speed up the yaw rate). The others are screwy misattempts.
No near crashes on the screw ups. Managed to recover them all.
Very psyched. Will try to get a few on video next time.
Just had to brag a bit.
