I'm in complete agreement, there was a ton of fuel pouring out the back of that airplane, I just didn't want to over state it.
Turbulence, I can't answer for whether someone is not being courteous. That's a different issue. Someone asked how to hot fuel, I answered. End of story. If it was dangerous, it would largely not be allowed. Those that don't like hot fueling, are the guys that have the least need to do it. Reminds me of "old foggie" at my local field. Hot Fueling is "hip" "cool" , you know, like those tatoos on the back of those girls, or the nose rings in the local mall rats
Just kidding, I like to do it, so do others I fly with. I can't answer for someone doing it without a fire ext handy. I don't agree or disagree with that as I don't think you are likely to have a fire while doing it. I just don't see any danger in it. A wet start is far more dangerous to the model, and a crash is even that more far dangerous. A model airplane fire while fueling is not dangerous in my book as it's not going to harm anyone (too many of the old foggies will be saving your ***** so they can tell everyone how dangerous you are) interestingly though, that's not going to happen while you are hotfueling, it's gonna happen when you are trying to start a ram.
