>what was supposedly a small project ended up big and complicated
Welcome to the drone world! So many moving parts and one tiny mistake, you end up losing a $60k drone in the ocean (true story!)
That being said, regulations prevent flying drones of any size above people, unless the drone is high to certain altitude, because of all the dangers that bring, a small issues and the props will harm them.
Cool project tho!
Better than losing the expense vehicle prototype and the pilot as well.
