PaleDale June 9, 2020 07:57 PM Barometer? That has nothing to do with attitude stability, just altitude stability. I call BS on they cause of crash. Being a person carrying aircraft it should have backup systems and auto fail-over when one fails. nick101 June 9, 2020 08:11 PM It's noisy and dangerous as hell, where's the order form? :D Russell Ryan June 9, 2020 11:39 PM "bike begins pitching wildly back and forth like a mechanical bull in the sky."Thanks for that unrequited sensationalism... it TITLED calmy forward once... he began lowering... it TILTED calmy forward once again.... then when it touched down at an angle of course it flipped.You made me expect to see his butt flyin off the seat as he holds on for dear life... but that was a CLEAR well controlled malfunction.Borning.Shame on your sensationalism!(Shakes fist) Graeme S June 10, 2020 01:08 AM some things should NEVER fly Paul Marsden June 10, 2020 03:27 AM Looks like his mind wasn't on the job from moment of lift off. Things really get out of control when he takes one hand off the controls to seemingly adjust his helmet. I'm calling pilot error. KaiserPingo June 10, 2020 03:50 AM Yah, those rotors are no danger..., if you count risks like the Russians do. Rustgecko June 10, 2020 04:36 AM Lesson: Don't take your hands off the controls for a celebratory air punching when you've only be in the sky 10 seconds. minivini June 10, 2020 06:12 AM Pretty sure tapping his helmet was a signal that there was a problem. And, yeah - the way it rotated on the ground, the pilot escaped injury mostly by luck. paul314 June 10, 2020 06:36 AM I guess it's possible for a failed barometer to cause the flight control system to go bughouse if it's on the same bus as all the other instruments and fails in a way that messes up all the communications on that bus. But if so, it's a sign of garbage hardware and software design. All of those sensor-type parts are under $10 a pop, and a $150K machine should have multiple copies, all isolated, with voting and failover. It also looks from the video as if the excursions from stable flight were increasing as the vehicle headed for the ground, which is another bad sign. martinwinlow June 10, 2020 06:41 AM What's worse than loosing control of your experimental aircraft at 100' AGL? Realizing you are surrounded by high speed chopping machines at very close range with absolutely no protection. Darwin award soon to follow.
