If you're planning on going high, make sure your battery is well charged. From 500m it will take 4 minutes and ten seconds to get back down. And that's after the climb to that height plus allowing you some time to take pics etc. Also, the alignment of the antennae should be changed if you're going straight up from the home point. I did it once - up to 500m in rural Ireland where nobody ever flies in a light aircraft or helicopter. The views were completely different from that height.
