I wish I saw some stuff like that when I was in school!

There are a few types of people out there- and two of em are the worriers, and the doers. I'm more a do-er. Just fly within 'reason', dont be stupid and triple check to make sure everything is charged and maybe even range checked. Then go for it. 15' IS pretty close (at speed anyway), hovering- it gives you more reaction time. Glad the kids loved it. Way cool. Dont trip out about it either- just remember this thread next time you do a demo!

Never really trusted "failsaves" myself either.
