Last Christmas my youngest son received a remote controlled drone. It was a nice drone. So nice, in fact, that it required 10 AA batteries. Four batteries went into the drone itself and six went into the remote.
After a “crash course” in drone flying, hubby and the three aspiring pilots took the flying terror outside. It was a clear and fairly warm day for late December so take off was a go. The drone proved difficult to control for the little hands of the the boys, and my husband was forced to keep a vigilant eye on their piloting. After a bit, they were cold and chose to come inside. The drone was left on the kitchen counter and the boys dispersed to reek havoc on another part of the house.
A short time later, my husband took a phone call in our home office and the drone took an unsupervised flight compliments of my nephew.
