Building a RC pilot kite

So I can’t be bothered pulling the lift kite around every time I want to land… Has anyone taken the next step in automating a single line lift kite with http://ardupilot.org/planner2/ I managed simple steering by remote about 5 years ago… I want to try again with the fancy new controllers. Is this what KiteSwarms runs on?

Uni Stuttgart successfully test flew a model airplane with autopilot.

Airborne Wind Energy: Successful test flight! | Video | Institute of Aircraft Design | University of Stuttgart
During the student seminar “Wind Energy Project” at SWE, a student team developed and successfully tested a scaled "Airborne Wind Energy" (AWE) model. For this purpose, a commercial model glider was modified to allow for autopilots and remote controllable tether connection. In addition, simple flight controller have been developed to conduct AWE-typical flight maneuvers in tethered flight. The controller code developed is based on the Awesome-Project of University of Bonn. The code will be made public shortly.

Paragliding kites

Met the maker of https://gliderbase.com/ by chance. It’s a database and comparison tool for paragliders. They are amost exclusively LEIs with a few single skins. Price range from about 2.5 to 4.5 k€ Don’t know how well they are suited for power kites, but if anyone wants to abuse one that’s where you can start looking.

Calculating drag [+lectures and books on Fluid Mechanics]

I’d like to be able to calculate drag. Here is a lecture series on that: Physics - Fluid Dynamics (19 of 32) The Drag Coefficient – Michel van Biezen Notice how the drag coefficient of a streamlined body is 0.04, versus 0.82 for a long cylinder.
