I’ve acquired a Holybro S500 full kit with a Pixhawk 6C running PX4. I have problems with engine number 1, that seems to turn off intermittently when running at high RPM. This error occurs both during engine test and during flight. It is not hardware error on the engine itself (I have switched engines to rule this out). I’ve upgraded the Pixhawk to latest edition. I’ve done several ESC calibrations, carefully following the instructions. I’ve tried both DSHOT600 and PWM, with exact same behavior. The error always occurs so a flight longer than 5 sek is not possible. I’m using QGroundControl. I’m now leaning on some kind of error with ESC for engine number one because I’m running out of ideas…
Would be great if anyone had any suggestions!
