Well in almost 20 some odd years of racing F1 RC cars I've had both front and rear wings broken off in the middle of the race and they didn't affect the handling. We did all our racing in the past with Tamiya Sport Tuned motors...I'm not saying they have no effect...just that you really got to get the moving before they have enough of an affect.

...wait, whut?
While I appreciate the value for money in the F109, I do feel it could be better, mainly because some parts are just too cheap. I hope this F113 takes it there.
Yes. Although I seriously doubt it's going that way with bodies soon.
The rear wing smells strongly of TRG. It's been the standard wing here for most drivers. Not too sure about polycarbonate front wings though, I like mine to be able to take a bit of beating.
From testing back when I was still doing the Dutch nationals, I can tell you that both wings are quite aerodynamically active, at least with the straighforward TRG-type wings. We didn't go overboard, but the low-drag TRG (A-type, from the top of my head) front wing we used on some large flowing tracks would not work on our home track (unless you like the grass at the end of the straight 
). We did some improvised windtunnel testing too, to compare the effect of various wings, but I don't remember the actual downforce figures.
I do agree it's nowhere near the downforce-to-weight ratios the real cars do, but there's more to that than just the wings, too.
I seem to recall the Corally F1 body is actually a Protoform. It's still available.
I have the opposite experience. Lose either wing, and you might as well retire. It depends on tyre grip though, of you have enough mechanical grip from your tyres you might not need the wings anyway.
A picture I found on 3Racing's FB page shows the new FGX front suspension. Looks very interesting, although it's the sort of construction that could suffer heavily from poor materials and cheap parts.

So, my questions to the masses; is this the direction F1 should go, meaning, performance over appearance? Is F1 seeing the beginning of the sedan car phase, where bodies are morphed and stickers are the only thing left that resembles the real car?

Until recently our races were done on untreated asphalt of very low grip. The best grip we had was with the Tamiya cap tubes glued over foam tires. Even then you had to be very careful on the throttle. I imagine with higher grip and faster motors and a bigger track that may be true but still that goes to my point...you really have to get the cars moving for the wings to be effective. I even had other racers finish the race with wings just barely hanging on but you couldn't see it on the track and even they didn't notice a difference.

. On my home track, lose half a front wing and you can't take any speed into the corners. Lose the rear wing, and you end up backwards at every corner. You can still make the corners, but you lose seconds, literally. We're running on foam, on an 250m purpose-built 8th scale track. Currently we're running the Tamiya Formula Tuned 32T motor as spec, back in the days when we still had F1 nats we ran a 16 turn. The 32T is less than 2 seconds slower. (around 20 secs, currently).

ps. I mentioned the 79 (late 70's), lotus because it is a body that is actually available at the moment.

Interesting. We do run a fairly fast, large track, so we do actually carry quite a bit of speed into the corners. Could very well be the difference. All the occurrences I can remember happened either had my home track or similar nearby tracks. Might have lost wings at the smaller tracks, but I guess I lost wheels too then . On my home track, lose half a front wing and you can't take any speed into the corners. Lose the rear wing, and you end up backwards at every corner. You can still make the corners, but you lose seconds, literally.

The Protoform bodies are just as nice as any of the other aftermarket F1 bodies.
TRG
Zen
Cross
the list goes on,none of these include the parts you are talking about.
I wish there was more compaines that had complete body sets ,but Tamiya is the only one with enough money to do it,Protoform was the only company in North America to make F1 bodies. Its a shame as the bodies are just as good as any other aftermarket company.And can look great if you have the skills.

translation: green dot is downforce generated by the front, pink dot is rear downforce, yellow dot is total downforce. orange dot is drag. unit is grams. 1N ~ 102g on sea level
