I am about to fly a Litchi mission that I created originally in Google Earth. I will be flying up and down the side of a mountain to an elevation that is about 500 feet higher than the home point. The craft will fly at a constant 150 foot altitude AGL, thanks to Google Earth. My worry is, do I need to set the RTH height higher than the highest point on my mission? That would mean a 700 foot RTH height. I am guessing the answer is yes but I thought I would throw it out there. Thanks! Since this is a Litchi mission the craft will fly on despite being disconnected from the radio (which I do not believe will happen), so the only reason for a RTH to happen is if I push the button.
