I have used many remote control (r/c) vehicles, boats, planes, and helicopters over my life. The most fascinating advancements in recent years has been the stability and ease of flying quadcopters. I really like how many can now carry GoPro video cameras for some amazing aerial footage. A friend of mine recently informed me of this amazing new quadcopter, the Stingray 500. Here is a video review below. If you have limited time, jump ahead to the 4 minute mark in the video to see some incredible examples of what this is capable of.
