Yes - adopt Joe Hunt's DOD 3D flying guidelines. My club adopted them and most members are quite happy with them.

Speaking of mechanical failures, here's a video of a jet biting it after some sort of structural problem. Tell me honestly, do you get a warm fuzzy from this? Just imagine if the failure forced the plane to go left instead of right.

I keep hearing about how people are afraid of new pilots coming down low and hovering their huge planes and causing danger to those around them. Have many people have actually seen this happen? Sure, hovering low is an awesome aerial stunt, but it is usually done by people that have enough skill and maturity to do it safely. I don't think the same can be said about people who stuff standard servos in their G62 powered fire breathing, 30lb+ Mustangs, doing passes down the flight line at 150+ mph. Which plane causes more danger - the one travelling at 100+ or the stationary one? There is risk in everything, and I dare someone to prove that hovering low and touching the tail is more dangerous than any number of other RC activities.
