Look guys, the point I'm trying to make, and it's not that hard to understand, is if nobody ever tries to do something new or different, or push the limits then nothing will ever improve. A reasonable person can try new things and still be safe at the same time. I for one will not put up with anybody telling me I can't do something. I don't intend this to be bragging but I'll put my 15 years in the hobby, masters in engineering, and engineering work experience up againts anybody if they think I don't know what safe is. If you're happy to follow the rest of the sheep around in circles that's great for you, but I will bet anything that some time in the future everybody will own a turbine RC and be learning on them as well. Maybe not today, maybe it will take 100 years but it will happen... and why will it happen? Because safty minded, educated, non-followers will push the limits. And unfortunately people will cuss at them and hate the along the way. Everywhere you turn you see something that was considdered unsafe at one time and now nobody thinks twice about it. Planes, cars, trains, electricity, etc. How about driving 75 mph (don't lie. everybody speeds) on the way to the RC field to learn on your turbine trainer. The drive there was probably more dangerous. Please stop trying to fill everybody's life with fear because you don't understand. It's a simple engineering task to be solved, and there's nothing safe or unsafe about it. People can be unsafe, the task itself is NOT unsafe so unless you know who's involved you can NOT judge.
