Hey guys My buddy and I are new to the drone world. We had an idea to use drones to fly around with a flag or advertisement of some sort around populated areas. Here is a link to the survey, if you have additional comments or drone specs that we didn't address please comment below, we'd love to hear your comments/concerns/suggestions as we are in the beginning stages. SkyView Media Survey

that is awesome! I had an idea of using a projector but we decided it would be too heavy to be useful.
You can get 12v projectors, and remove all the casing you don't need to make it lighter. I tried it myself a long time ago. The above idea is much better though, more up to date and a lot safer having everything enclosed inside a frame like that.
