I think this is more aimed at the 3D newbie. I have'nt 3d'd in real life, but I try it all the time on my RealFlight sim. At least a few times per flight I end up pulling out quickly and may fly over the pits to do so, sometimes burrying it.

I wouldn't try this in real life at a low altitude until I was very comfortable with it at higher altitude first. Problem is, a lot of people don't take this crawl, walk, run approach. They see their friends do it, then try it themselves and get themselves in over their head, so to speak. What happens after that is sometimes just as much chance as it is controlled flight, with potential havoc and injuries on the list of what could happen.

I'm not for making this illegal. I wish the AMA would make it a guideline, not a mandatory rule. I'd like to be able to do it someday, once I got the true skills.
