I've changed my P4P parameters to eliminate the 500M flight ceiling, so I can climb mountains higher, always within 400' of land. I've climbed as high as 3800' above my launch point. The high capacity P4P batteries allow such climbing feats. It's an incredible feeling when I fly to the top of a mountain 14,000' MSL high and look around at the Rocky mountains. No other craft can do that, to my knowledge.
