The floor price only lasts 24 hours. If nobody grabs it, the price goes back up to $40 and the 30-day countdown starts again.

Worth checking before you write it off:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOn the F405 Wing, the servo rail is powered by its own BEC and the \u003cstrong\u003eservo voltage jumper\/pad\u003c\/strong\u003e. A wrong jumper setting or no rail power can make outputs look dead.\u003c\/li\u003e\n\u003cli\u003eIn INAV, servo outputs only work once the right \u003cstrong\u003emixer\/platform\u003c\/strong\u003e is set (airplane\/flying wing) and outputs are assigned. If the rudder isn't mapped to that output in the mixer, it won't move. Try remapping the rudder to a spare servo output; INAV and ArduPilot both let you reassign outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIf it's genuinely faulty\u003c\/strong\u003e (a dead servo BEC or output stage), the rest of the board (FC, gyro, OSD, UARTs, motor outputs) may still be fine for another build.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecs (when working)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMatek F405 Wing V2 · STM32F405 · ICM42688-P gyro\u003c\/li\u003e\n\u003cli\u003eINAV \/ ArduPilot fixed-wing FC with built-in BECs and OSD\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eChips on the board (for parts hunters)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMCU: STMicro \u003cstrong\u003eSTM32F405RGT6\u003c\/strong\u003e (168MHz, 1MB flash)\u003c\/li\u003e\n\u003cli\u003eIMU \/ gyro: TDK InvenSense \u003cstrong\u003eICM-42688-P\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBarometer: Infineon \u003cstrong\u003eDPS310\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOSD: \u003cstrong\u003eAT7456E\u003c\/strong\u003e · microSD blackbox\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eChips are as listed by the manufacturer for this model, not checked on this exact unit.
