In the latest firmware version 1.15.4, I simply can’t find the throttle idle parameters. As a result, the aircraft starts ascending as soon as I arm it, and I can’t make it descend. In the end, I had to resort to a crash landing. Its idle speed is extremely high. I tried calibrating the ESCs, but it didn’t work either.
I was going to say ESC calibration and/or adjusting the idle speed using the parameters, e.g. if connected on Aux: PWM_AUX_MIN1. Easiest to adjust in the QGC Actuators config panel.
I suggest to try it out in small steps:
- Remove props and try out parameters.
- Put props back on and strap drone down (e.g. with a short rope) to test it.
- Fly again.
And, always have a kill switch configured for initial tests like that to cut throttle immediately when things aren’t good.
