I have planned a Litchi mission by cruising towards a dam (approx. 130 below the top) and rising above it, continuing on past the top for approx. 1/2 mile and then returning to the starting point. The starting point is below the dam, thereby putting me out of LOS after reaching the top. It is my understanding that Litchi will complete the mission and return to the home point even with loss of signal from the RC. I plan to have a spotter on top of the dam and the mission will be flown with no risk of human interaction. Am I ok with this? I will do a trial run at low speed in advance. Thanks for your input.
