Its not aero neutral. It might be at 0 degree AoA, but its HIGHLY CAMBERED. Its still a DF producing wing.

Edit : The flap is not that cambered after all
You gotta ecplain me the part with camber; how is the flap going to produce downforce when in the up position?

Do the teams run rearwings which reach the maximum height (950mm) if they use smaller wings? I would do the wing lower.
Or is it not permitted from the regulations?

Shape! Due to profile, the air on each side goes at a different speed, pulling car onto track. Look at an aircraft wing (in reverse) It creates lift, even when the plane is flying level. I presume that 'camber' refers to the amount of curvature. The greater the curve, the greater the downforce.

Without seeing the flap in profile it is almost impossible to determine the upper and lower cambers, if the camber is symmetrical it will be aerodynamically neutral at 0 degrees.
To my eyes it looks like the flap is symmetrical and aerodynamically neutral. IMO this would make sense because you could then easily determine if the flap produces downforce/lift or has no affect simply by changing its angle when open. presuming that is legal of course.

except that the flap doesn't have a curve. Like beelsebob said, it's flat. The main plane indeed is curved. Well if that was what pierce89 meant with camber anyway (weird of using a term ussually applied for the angle of the wheels here for a wing).

Not quite such weird use really, it's a pretty standard term when referring to an aerofoil. Hope the below link clarifies the matter:

Does not look flat on the ends, but the wing fences look flat. Variable camber foil shape?

It seems rather bulged, as if it is convex shaped instead of concave(or the other way around, you get the point)

I'm not sure what point you're trying to make. The point I was trying to make was the wing profile looks symmetrical to me, at least in the centre, and that I would bet heavily it comes horizontal, or close to, and thus parallel to the direction of air flow over it. Thus, that it's aero neutral when the DRS is open. Are you agreeing or disagreeing and to which part?

You're obviously trying to make a point so why lie and say you're not? Are you still in high school or what with your whole "epic fail" comment. Why not be an adult or at least try and act like one & engage in meaningful constructive conversation? If you disagree with someone, say so. But posts like above are exactly what this forum doesn't need.

@Wesley agreed, it definitely looks convex. Probably just an optical illusion of course. Will look for pictures to confirm the true shape.

Even if the airfoil is neutral, it's not aero-neutral because of the gurneyflap

What benefit is there from running the inner R cascades to the outer ones?

Wouldn't the outer elements help with flow over the tyres?

I would bet that the inner R cascades are there partly (or even mostly) to condition flow for the back of the car, while the outer ones are simply there to try and use the air as hard as possible before it hits the mess the tyre creates.
