I am working on a project in my neighborhood which is going to be helpful to the city government in dealing with a current issue. One of my neighbors has been shining a laser at the drone to try to interfere with this project. My neighbor who has been shining the laser is knowing as a local whack job and the police have gone out and asked him to stop. On two separate occasions when I have flown directly over his house at about 100 feet and going about 30MPH the drone loses control and starts spinning clockwise. On both occasions I was able to get it home but it was quite difficult. Does anyone know if this individual could be causing this and if so what is he doing or using?
