While flying last week I encountered an issue. During operation, our vehicle seemed to lose power and drop out of the sky a couple of meters then recovered and was controllable. I flew it again and was able to replicate the issue once the vehicle was about 50 meters away from the controller by hovering and waiting.
Here are the log files:
#1. Occurs at about 04:41 (there appear to be two dips in the throttle log)
#2. Occurs at about 10:01
As far as I can tell, these were caused by a sudden and violent change of yaw rate set point for #1. I’m not sure about #2.
Equipment and software:
PX4 Version: 1.7.3 Stable
Pixhawk Cube 2.1
Transmitter: Taranis X7 with Orange RX 2.4 GhZ DSMX transmitter module
Receiver: Spektrum Racer Receiver (SPM4648)
Winds from 330(+/- 20 deg.) at 8 knots, clear day, 12 degrees C, 30.36 inHg.
If anyone has experience with this phenomena, or suggestions on how to prevent this from occurring in the future, please let me know.
