Ken didn't clean up the thread because people are debating two sides of an issue, he cleaned it up because for some reason it can't be done without taking pot shots at the people posting thier opinions. Sadly the airwaves are full of such garbage for the last several months until November, I'd really rather see better here at RCU.

That aside.

How does one rate a field for turbine use? Or giant scale anything for that matter? Where do we draw the lines? If the model is equipped with brakes if its a short runway? By wingspan, engine displacement (or pounds of thrust), model weight?
