Hi tlojak38
You are doing the right thing, asking how to better determine how close your plane is to obstacles in order not to crash into them. I have been flying RC since around 1972. I have tried to learn from every one of my MANY crashes, including two mid-airs. A few years ago I realized that we humans are not able to determine how close we are to an object, once the object is further than our binocular vision allows. (I think that distance is something like 17 feet, and is called depth perception). So, we are actually flying blind with regards to the location of other objects. Recognizing this now, I fly very far away from any object. I emphasize that; VERY FAR AWAY. I also now try to land my plane only directly in front of me, flying right to left, or left to right, only. Only when the plane is directly in front of me (not coming toward me or away from me) am I able to properly determine how close to the ground it is, and, more importantly, how close it is to stalling. This is due to the changing geometry involved as the plane comes in for a landing. That changing geometry robs you of your ability to estimate correctly how close you are to stalling, and make the required correction. Comments from you or anyone?
