    LVC on an ESC puts it into limp, or "off" mode. Flying, for a multirotor means 20-80% throttle. Limp mode on an ESC is going to be 5-10%, if it doesn't just shut off the motor power entirely. Both of which will make it drop like a rock. Flight controllers need to have the battery sense lead hooked up and calibrated. And then be set up with a "landing plan" to deal with that.

    There are so many ways this could have been screwed up by the pilot that it's not worth trying to detail them all.

    and that's on top of the potential of him running into a chemistry bound wall when his packs got under 3v/cell

    And a piece of Styrofoam killed a bunch of astronauts not too long ago. And kite string around a helicopters pitch links are just as deadly. ever see a Pitts after a balloon hit the prop?

    Oh, don't get me wrong. I'm on your side of the fence when it comes to drones in the airspace, especially around full-sized aircraft. My comment about a cage was in response to the video with the drone crashing on the ski slope. It was meant as a suggestion for protecting the drone in the event of impact with the ground. Seeing that drone turn into a bunch of plastic kindling did not hurt my feelings at all. :gig:

    I've seen random voltage cutouts on racers before. Not sure what it was, but I could ask around if need be.

    They've had BRS for drones for awhile now, at least, I've seen some pretty established looking companies. I can't find the names any of them in the drawer of my desk that passes for a rolodex, but I think if that anything worthwhile could come out of this incident, it would be that the "Point-in-Space Camera" mission be considered established enough to establish specific weight classes and safety precautions, such as but not limited to, the aircraft must carry a B.R.S. if its flying weight exceeds X lbs. at altitudes up to Y, with speeds up to Z." - or something like that. I know the FAA ran the numbers for what would cause a lethal head strike, anyone remember them?

    EDIT: Remembered one!

    And how many predators and brethren were lost or simply stopped responding until they ran out of gas? It will be like NEVER when cheap drones have all the safety features..

    I heard on the radio that the local rural electric coop is using drones to help maintain the high lines.

    Ok, jumping onto a power line is a job I would pass on...used to enjoy the guys in the short wing Pipers flying the power lines and tank lines near our house years ago. I did see a Piper Pacer dangling from power lines just off of I40 at the Yadkin river bridge...think there was a large aluminum smelter there, the guy tried to fly between the lines, snagged his gear, we saw it dangling from the line, one tire stuck over the wire. He was just a bit too early in training for that job, I guess. Drones would do great in that job...the trick is just to keep them out of human carrying airspace. Wonder what would happen to a heli if it hit a drone? Enough to take out a blade?

    If I were to have an engine failure over very inhospitable terrain/trees, and there was a high-tension powerline nearby, I think I might be tempted to try to snag my gear on the line and let it dangle there until help arrives (provided I was able to call for help prior to landing).

    Hmm, I would've expected that from a Navy guy, but not from you!

    He should have been, general population RCers need to start taking responsibility seriously.
