It's been a little while since I told this story and it was on a different forum, but just so you know, these incidents can and will happen and not just with RC airplanes.
I was practicing flying my RC Heli at home one beatiful evening when one of our dogs suddenly took an interest in the heli that was impersonating a frisbee with incredible hang time. As I was nearing the end of my tank of fuel, I opted to land closer to me so as to avoid the dog. Our other dog, normally the obedient one, saw that the first dog had paid considerable attention to the hovering heli so she started to as well. I called her back, again, and again. Finally, when I yelled at her the third time, she turned away and started back towards me so I started to settle the heli down. She turned around and lunged at the heli, so I immediately fed in full right collective to get it away from her and the heli rotor contacted the ground and her at the same time and the heli then proceeded to thrash itself to death as the dog ran off limping. After finally evaluating her situation thoroughly, a trip to the vet was in order. She ended up losing 1/3 of her tail at a cost nearly double that of the repairs required for the heli (not cheap, either). What a nasty accident.
Moral of the story...Stay alert to ALL possible distractions and intruders into the flying area and pits. The pilot must take total responsability for maintaining a safe zone around the rotating parts whether they are props or rotors. I still love this hobby but am very aware of the possible dangers and I only hope that this thread continues to keep my fellow modellers aware of the responsabilities we have with these models.
