I've never been a gymnast so I cannot relate to what exactly goes on in a gymnast's head when a fly-away is executed. And, I definitely don't have a drill to offer.
It's just that from what I've seen, fly-aways tends to stand out with respect to fear over pretty much all other so called "fundamental" skills. I've seen a gymnast delaying competing at L7 after she had mastered everything else (and beyond) for over a year. They also appear to be something that can be easily "lost" (and regained later eventually) due to fear for someone who has comfortably done it for a while.
So, gymnasticsluvr19, just to let you (and your friends) know that you're not alone being scared on this. Keep up the courage and your hard work! You'll get it soon.:applause:
