Same weather as yesterday. I mounted my FlyCamOne2 and wanted to give that a try. Somehow, it managed to record 122 pieces of video instead of the 2 shots I planned. I glued the pieces together, but the result is “jumpy”, the quality is bad, it shakes like hell and is overcompressed, but just in case you still want to watch it: 2m18s, 13.7MB (x264 video, ogg-vorbis audio, matroska container, VLC plays this just fine).
After 2 minutes of flight, I suddenly hear a loud “tack”, but didn’t see or feel anything strange. I landed the heli promptly anyway to do a full check. The sound was fairly loud, since the heli was at least 100m away and was clearly audible. I checked the main and tail-drive gears, but none of them showed any damage. The rotor looked OK as well, until I examined it a bit closer:
The plastic foil at the top-tip of the blade somehow got loose and teared. This tip was traveling at around 430km/h (67cm from the axis, rotating at 1700rpm), which makes a lot of noise when something hits this wind.
Just swapping the blades with the spare (wooden) blades had my bird ready to fly again.
