"Very nice job. Love that. I tried to convince my professor for my PhD to develop an intelligence for thermal soaring. Instead I did swarming for UAVs which is and was very interesting too. Thermal soaring just has something magical to it. Crossing…"
"Oh sorry my mistake.
In QGC under the menu Wigets is the Analyze. Use that tool to plot in real-time that data. My suggestion is to connect the Pixhawk directly via USB to your computer. The data update vie your telemetry link is slow and might not…"
"Same direction, but it looks your external sensor is upside down. I would for testing the external or both internal sensors rotate 180deg around the x-axis.

Hi Armin,
Thanks for the insight. Actually, I have set the system…"
"I guess you need to adjust the PWM values. Also consider that those ESCs usually also have reverse. I would expect at a 1.5ms PWM pulse with the motor stops. Since multirotor ESCs are usually stop at a 1ms pulse with your flight controller is…"
"If I understood your right in your initial post right: both the flight controller and the GPS pointing to the back. In that case you should have not a compass inconsistency, except you haven't calibrated them. You and Chris are right, but i have the…"
"I just would make sure that you limit the maximum servo position of every servo. I also agree the integral parts could run in different direction, but if you make sure that you have some kind of anti windup for your integrator in a range where it…"
"I was assuming that it would be a cascaded PID. Straight roll/pitch I highly would doubt that it would work reliable, if at all.
The integral part might be actually a port of the solution. In normal operation it might could happen that one integral…"
"I understand. Also additional complexity may not reduce the risk if not done very carefully.
I agree. Your system needs to be tuned towards robustness that it can handle safely one servo / flight controller failure.
You are also right you really…"
"Nice project! I would consider some feedback from the servos that you know which one failed that the other ones can compensate for the lost travel. You may want to consider a module in front of every servo which is connected to all PWM inputs and to…"
"The answer depends what on what you want to do exactly.
You can control multiple vehicles from Qgroundcontrol, but you need to select the vehicles separately in QGC and tell them what to do.
What you need to do is to give all the telemetry modems…"
