Can the P3 take off from 4000 meters above sea level (13000 feet)?

I want to take off from 4000m above sea level in the mountains, then fly only 50m above my takeoff point.

Yes, you will not have problem with it.

According to the specs you can fly up to 6000 metres.
4000 m shouldn't be an issue.
