"you have no power logging (vbatt/current)  - so it's hard to tell you the battery performs, but it's apperently hovering at 73% throttle, and while falling it's going to 100% so it needs much more thrust. plot CTUL.ThrOut …"

"Without a battery monitor it's hard to tell but the motors went to max and it still lost altitude so I would say it ran out of power coming from the battery.  Possibly a weak battery."

Alternatives to using set_overrides() rcin function to set PWM values on PX4

Hello,I am using the ardupilot/arducopter open source code to try and manually set the pwm values on the four channels corresponding to rpy and throttle. I am usinghal.rcin->set_overrides(array, 4)to change those values. This does seem to work.I am looking for more robust alternatives that can help me "hardcode" the values for let's say my own flightcontroller. Or should I stick with the above method?(I am currently not using MAVLink or anything else, just directly writing my usercode and…See More
