Afraid that wouldn't help much at our field. I have observed flags on the road to the field flapping straight out. This is only about 1 1/5 km away. The wind at the filed is barely being moved by the light breeze. When you get such big differences so close together, how can you predict what field conditions are going to be like?? Therefore if I want to fly, I take out at least 2 different types of planes. I make sure that one of the planes can fly well in windy conditions and the other can be anything else.
