I was out flying over an alfalfa field 2-3 years ago and buddy of mine had his Nexstar in the air. I dared him to fly it under some telephone lines along a dirt road behind us. He did it a few times but on his "last" attempt it hit the cables at full speed. The cables stretched like a bow and arrow then tossed the plane backward about 50 feet. The poles and cables were were moving but nothing got damaged. I felt bad for him but it was pretty funny to watch. Luckily they weren't power lines. We should have been flying at the local club anyhow.
