The floor price only lasts 24 hours. If nobody grabs it, the price goes back up to $200 and the 30-day countdown starts again.

The fault we confirmed on those was a \u003cstrong\u003efaulty gyro with \"heading drift\"\u003c\/strong\u003e: the quad \u003cstrong\u003eyaws by itself\u003c\/strong\u003e, sometimes a sudden sharp twitch to the left, sometimes a slow continuous drift. On the bench, the heading in Betaflight creeps steadily even with the quad sitting still.\u003c\/p\u003e\n\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIt looks near new, and nothing's visibly damaged.
