As promissed in another post, I have created a document that describes in detail how to use the Proline 21. It is a PDF that you can download from here:
https://dl.dropboxusercontent.com/u/22810025/Proline21%20How%20To.pdf
The content will save newbie's a lot of time and might give insights to more experienced simpilots.
I gave it a version number, so, if I need to change something, I can update the document and the link above stays valid.
Enjoy,
Dirk
