Apologies if already posted

What I find a little concerning is the fact how 'slow' the ARW deploys. Supposedly some teams let the ARW 'open' until breaking (I'm sorry I don't remember exactly where I read that) which triggers the reset.

That would mean that if the car is travelling at say 360 km/h (100 m/s) and the resetting of the wing takes approx 0.2-0.3 seconds (estimate according to the video) that would leave the first 20 to 30 meters under breaking with following results:

1. Breaking is not 100% at first
2. A strong aerodynamic df shift towards the rear
3. If KERS kicks in to load that would increase the chance of lockup in the initial breaking phase (Although I guess this could be surpressed)

If you now assume that in a race you can only use it to pass an opponent, and the FIA are trying to make it as hard as possible, they are risking a overspeeding unstable car under breaking, probably not even on the ideal racing line.

I don't know what kind of balance shock would be generated, if the ARW can be set to deploy in 0.05 seconds, but I think that is what I would try to achieve.

Has anybody watched any other resetting of the ARW of other teams? Are they the same speed as the RB?

The Sauber is much faster.

I imagine they can make the flap move as quickly as they want it to. A slower transition might make the change easier to deal with from the driver's perspective. Maybe during quali they will ease the flap up and down slower, whereas in the race it will be sped up to make full use of the one second limit, as in the Sauber video.

It seems like the starter slit is just being used as a hot air exit. I wonder what effect this has.

WOW! Is that from today? That RB7 exhaust slot/slit/cannon has severely downsized!!

From this angle, it looks like it's shorter too. By this I mean that it appears that it finishes closer toward the front of the car than before.

Very uncluttered back end in general actually. Those suspension members look a bit fragile for my liking though?

Are those hot air outlets on the left and right around 'Total' word new?

As to my source (question from few posts before)... I've found it somewhere here on this forum, but I don't know where, because yesterday I was reading two weeks of post in all car threads for few hours. Of course it's nothing official though.

I'm sorry, where is the exhuast in this picture?

Interesting, from Ted at the BBC

The Red Bull RB7 is using its moveable rear wing in places no other car can, for example in the middle of the fast corner heading onto the main straight.

A nice trick, but irrelvant to race performance.

The ARW is only allowed to be used a straight. So that could be why other teams aren't using it on bends.

I am pretty sure Ted's comments are reflective of the level of downforce the RB has. The fact that they are able to shed so much downforce mid corner without running wide should be testament to this.

The Hot Air exhaust was smaller on sunday aswell.
(yes this photo is from sunday)

Maybe RB slower ARW actuation is the key to them being able to activate (or deactivate) their wing earlier in the corner than other teams??

Any idea what the small teardrop shaped fairings are for on the front wing's upper elements?

Or their ARW isn't as effective at shedding downforce... one or the other.

Its pretty clear from Ted's comments that he was referring to the car having impressive downforce as opposed to the Rear wing stall being less effective than other teams.

Lets face it everything on this cars predecessors have been pretty good, so its unlikley they have produced a RWS device that is not as effective as other teams.

imo it's more likely that having a "super fast" mechanism disrupts the airflow too much and causes the airflow to detach when activated.

correct, leading to instability.
