I created a new kml file with a bubble who include links to Mapy.cz and Wikipedia and the name of the author the addon castles. Mapy.cz is a Czech website who provide interesting views and info about the place. Wikipedia link show several links about the castel that you click.

I added some pictures of castles and fligthplan in google Earth and also both (pln and kml)  in LittleNavMap. With LittleNavMap you will see your aircraft on the flightplan and surfing between castels. You can also create your own flightplan with the KML file load in it.

Leave your plane alone and surf your drone between castles and learn more along the way with Wikipedia and Mapz !!!

Thank you so much to "laudey1" the author of these very nice castles who is dowloaded here:
