This was only my 4th flight with the Bojiang S1 quad, with RunCam-HD attached via velcro underneath. Took off from my back yard, avoided my radio tower and antennas and got it up to 400 ft. Wind started blowing it out toward Lake Erie! I panicked and tried to go to "High Rate", so I could fight the wind. Unfortunately, the rate button on the Bojiang S1 is not where its at with all my other quads, so instead of High Rate, it went into Headless mode, I got confused, and the quad came down (props first) from 400 feet. It went through some trees and landed on a neighbor's front lawn a block from the lake's shore. I went to try to find it (thinking it was in the lake) and was called over by my neighbors, who turned it over to me. After checking it out, I did a small demo flight for them in their front yard, since they'd never seen a "drone" up close. The Bojiang S1 has not been the same since this event, but the RunCam-HD survived. As proof, there's another video posted showing some video from a local Marina. Tough Camera!
