we added some small changes in rules:
You can find them here
Furthermore it turned out that some pilots are using the chance of changing class as possibility to delete a bad scoring in the first flight so we decided to stop that possibility of class change on thursday, so if you want to change class, please do it before.
I must admit that I didn't think about that possibility of "manipulating" the scoring and I'm sorry for the small unfairnes we caused by that. It seems that trusting in fairplay is still not the right way..
