Hi there, Is it possible to set max alt to 500 meters and go over 400 feet in Australia or does the P4 have inbuilt safeguards to stop this? Also will it fly at night or in national parks. I'm confused about things I read and hear and am thinking the P4 has programming to over ride the user and not fly at night or over 400 feet. Has anyone else heard This? Any assistance would be appreciated.
