The YMFC-AL quadcopter + a fresh breeze = great fun.

With little effort I fly the YMFC-AL quadcopter in a fresh breeze. According to the nearest weather station it was 5 Beaufort ( 18–24 mph / 17–21 knots / 8.0–10.7 m/s). The YMFC-AL is an auto-leveling Arduino Uno based quadcopter that is easy to build and fun to fly. Auto leveling means that, when you release the sticks the quadcopter levels itself. This makes it much easier to fly. The YMFC-AL is not a high level flight controller. The purpose of the YMFC-AL is to provide a simple and understandable code
