Just Joined...so I don't know where to put this drone application/use question. I would like this Drone to move JUST over my property at about 20 feet in the air, and move around this 100 by 200 ft. area...> by itself<...without bumping into my trees or other obstructions...a hands-free robotic memory learning drone ! I would use this Drone For Halloween, Christmas or other Holidays, to carry(hang) a Witch, a Santa, perhaps a flag for the 4th of July. I am science based...but don't know this technology. Is there such a Holiday Display Drone that I can buy at a reasonable price? Thanks, ddtjon Ohio/USA
