Getting all of my Camp Invention campers to form the letter "C" and the letter "I" was a little like herding cat. I kept telling the drone camera operator to be patient and that we could definitely accomplish it. I thought this should be easy...we had launched smaller rockets, took apart machinery to make movable/workable pinball games, and made our own race cars, however this proved to be one of the more challenging tasks we accomplished.
If you ever have to create a bird's eye view / aerial image of a group of people trying to make a formation.....start with a clear plan in place, encourage color coordination, and have them place their hands all in a specific spot. Do know there are state regulations enforced with using a drone camera. Click on my page S.T.E.A.M to hear of those regulations.
