If you have realflight and want to practice approaches with trees etc, download "Bingo Field" from the realflight download page. That's a fair re-creation of my field. With the hedgerow to the north, and the fence to the south, you will learn the approaches that work. I stand with my back to the one tree and windsock in the middle of the field, and use that as my runway. As you work on it, you can get all but the Sabre to land there. The wind usually comes from the north, or the south, so you get to learn how to make that work for you also. Good luck and keep up the good work.
