My comment about all rc aircraft being dangerous stands and is not speculation. Every instruction manual for every airplane I ever built, and every electric, nitro, and gas motor has ample warnings about the dangers of improper operation and potential damage to you and others. How dangerous they are depends on the level of capability and responsibility of the pilot. Any activity conducted responsibly is generally safe.
