I resemble yoyr comments. When others are sport flying , they are typically flying smaller planes and are hard to predict. When flying Imac the other plane in the air is typically much larger, and it is flying a predictable pattern. Typically an upper and a lower class pilot is flying at the same time, with two flightlines. An unlimited pilot burns up a lot of airspace with multiple maneuvers on the up and downlines they spend a lot of thme in the verticle, while the lower class pilots spend more time in the horozontal. I flew in a few Combat competitions, where there are 10 planes in the air at once with 30 foot streamers. Even in this seneario it is hard to cut the streamet much less have a mid air......As luck would have it I did suffer one mid Air. I was flying a 1/4 scale world models extra straight and level, when all of a sudden the left wing seperated from the fuseladge. There was a guy flying a small fase electric composit plane that was flying along straight and level when his plane dissapeared. After discussion of a few Bermuda Triangle theories we found a portion of his plane in my severed wing panel.
