After getting some more parts needed to prepare the Drosophila flies for the flight simulator and after breeding fruitflies for 10 days (that's their generation time) I could test the flight simulator.
This is a screenshot of the data I got from the 5 flies I tested until the ancient belt that connects the motor to the arena lost too many of it's teeth

The upper panel shows the average of the five flies. The lower panel the average of 230 flies I measured in the course of my theses. Red bars are training (reinforcement on), black bars are test (reinforcement off). You can see that they are very similar, showing that the test worked first try! Whohoo!
