I agree with this very much. The front end shape has a minor bearing on the handling, but my belief is the wing shape and size has a huge bearing. The position of the rear wing in relation to the rear wheels also makes a fair difference (see Crowd Pleazer for example)
The side plates for the wings I believe are intended to improve straight line stability some people are leaving them off to encourage the car to rotate quicker.
Hmmm, yeah. Some time ago, we ran a Honda Accord. I dunno the brand of body but it had a rather pathetic wing with no end plates at all. I installed a huge (rather illegal) wing and the difference in high speed traction in the sweeper was like night and day.
We had been running this Stratus 1 for quite a long time, so I feel pretty familiar with how it works, even with many suspension changes. With the new Volvo S60, I wasn't actually expecting anything to be different . . it's was just a new body to replace the well worn one, after all.
I can only guesstimate this, but I now think we had too much rear downforce on the Stratus, and there was probably increased drag as a result.
It therefore seems likely, that playing with wing settings/positions could be a half reasonable tuning parameter.
My point about the end plates was to differentiate between the integral ones that are part of most standard wings and the addition of the full plates that extend below the horizontal section of the wing.
The theory being that to discourage air flowing off the sides of the wing, those plates should really extend below the wing also, since it is not just the top surface that provides the downforce.
I dare say that some straight line stability is afforded by the end plates, but would expect that improving the efficiency of the wing is the primary motive.
But, yeah, I could see that by removing the end plates the body could still generate sufficient down force at higher speeds, but as the speed comes down, the effectivness is quickly reduced and this allows the car to rotate more easily. I dare say, that when faced with a car that is not rotating fast enough, we would typically alter suspension settings to achieve the desired result. Maybe we should really be adjusting the "Aerodynamic Aids"
I wonder if anyone ever put one of these R/C body's in a wind tunnel.
