Flying such a small device in heavy wind conditions is always going to be a challenge. Based on our experience, we have been able to fly in winds of up to 15 mph without significant degradation of control and video quality. Stability of the HEXO+ is enhanced by the fact it has 6 motors, a tilted frame and a special aerodynamic designed shell. If there is a considerable amount of wind, it will put more stress and load on the motors and batteries and your flight time will most likely be adversely affected. That being said, we are working on options to maintain a steady image so that wind will be less of a factor in getting those awesome aerial shots that your HEXO+ will capture for you.
While it does work through light rain, it does not yet work through heavy rain.
