Matrixpilot Glider add-on: brakes and auto land demo

Hi,MatrixPilot got upgraded with the helical turn method. I changed my code to follow this development.To add the auto land function, i needed better brake control. After that i created the auto landing script.The codebase has moved to Git. My code is here: https://github.com/KeesGuijt/MatrixPilotFor more info and comments please go to…See More

"Kees, I think that MatrixPilot LOGO has unlimited range, but it has never been tested beyond 32 kilometers. However, it should be easy enough to test the LOGO range using HILSIM, so if anyone is interested in using LOGO for long range missions, let…"

Hi,

Finally, an update about my project:

I have converted the telemetry log into subtitles, so you can see what's going on. This video explains a "Thermalling method for Model Glider Autopilots" in more detail. Best viewed in HD)
