I know that there are many here who do not agree with my first statement. Go ahead, read it again. To those I ask: If you fly from a defined runway, like a grass field that is frequently mowed, have you ever landed short, in the tall grass, when it was your intend to land on the cut grass runway? Ever wonder why that happened? I saw a large plane do that at our field just a few days ago. Our 150 yard long runway, by 75 yard wide runway was right there, yet the experienced RC pilot landed short, right into the tall grass. He missed the WHOLE runway. I have done the same thing many times. He thought he was over the field. I was watching this plane land, and I too thought it was going to be a good landing. Why was the pilot wrong? Why was I wrong? Come up with an answer that you believe is reasonable and explains what happened. Go ahead, you explain it! It is my opinion that when the plane is far away from you, you have no idea where it is located, relative to a fixed object, such as the beginning of the runway. You have to learn to compensate for this human inability to determine the location of our RC plane relative to another object at a "far" distance. I do it by coming in for a landing "relatively high" at the end of the runway, and then aiming to touch down near to "directly in front of me". I look forward to any comments on this.
