F1 Rear Wing - Adjustable attack angle

I made this F1 rear wing based on the 2017 williams car. I needed a rear wing for a aerodynamic testing project for school but couldn't find one that has an adjustable attack angle, so I made one myself using fusion 360. It works good and has a simplistic design. It can do form 60 to 0 degree of attack angle. How to operate: On the left side you are going to see a little level and some small dots, rotating the rear wing would rotate the level as well. The most bottom dot is indicating that the attack angle is at 60, the 2nd bottom indicates 50, the 3rd indicated 40, and so on until 0.
