Tonight I was flying one of my toys, this time a Phantom. Altitude: 120 feet, location: over my property. For the record, I live in a rural area, horse farms. About 5 miles away a large helicopter was flying away from me. When it saw my Phantom it took a hard turn and sped right to me at high speed. It was on me in seconds. It didn't fly directly over me but took a large left turn around my property and watched what I was doing. I ignored the intimidation and continued what I was doing, and he left the area. I'm curious if other RC pilots have this experience. Staring tomorrow, I will be wearing a GoPro on my head to document any further "incidents".
