So far I've had my P3S out to 2,100'/.4 mi. Ive just been keeping it close and not taking any chances. It always surprises me how fast and easy it will reach longer ranges. I know soon I'm going to want to see just how far this thing will go. How should I approach that? Do I want to go out and back as fast as possible to stay within battery limits? Or do you go slow & easy to conserve battery life?
