High Down Force Wings

High Down Force Wings
Do some of the aftermarket wings help with keeping the front end up when in the air on a Losi T2.0. i have the LOSA 8130. Sometimes, I don't want to throttle on a big jump in mid air to keep the nose up.
Do you find that maybe a jconcepts or ofna wing help keep the nose up more in mid air. ie. JCI0113B or the PRO6023-03 or OFN40906

Most wings have a "lip" on the bottom of the front. Most of the downforce actually comes from the BOTTOM of the wing if it has a proper shape- that lip trips the airflow and destroys that lift. The Associated wing doesn't have that lip- just a smooth shape. Much better aerodynamically. It is more like a wing and less like a parachute than the others. Does it have the most downforce? I don't know... you'd have to test it in a wind tunnel. Does it have the best lift-drag ratio? You bet!

Hmmm... aerodynamics principles say the best wing readily available is the stock wing for the Associated buggy.

What kind of affect does the rear/top lip on a wing have? I would've thought that this is the part that causes the downforce.
Tx for your time Domit!!!

each car comes with a wing wich has ben designed fot that car why would u change that?

Does the shape of the wing really matter for this type of application? are the rc companies really testing them using CFD programs or even small model wind tunnels? I find it hard to believe that these companies are actually renting time on super computers and using the navier-stokes equations to determine the best possible shape. I am a mechanical engineering student and i have just completed my second semester of fluid mechanics and it seems to me that the wing shape in the case doesnt do anything other then protect the engine head when the car lands upside down.

My Dad has taken in a couple of wings to his work (Sauber F1 windtunnel) and they have said that the Team Cobra Racing wing is better than the OFNA High Downforce one.

Thay have had a look at both and say that the lip as mentioned earlier is not good - a simple test we did was to dremmel it off on my friend's one and it did work; but not sure if that was phsycological or proper improvement.
I can notice the difference of the TCR one over the standard one, however I am yet to try it on my new car to compare to the Tamiya ones. However, the F1 engineers also said the fins along the elements help with straight line stability and the twin element design also helps channel the air to the correct place.
Just thought I would chime in, they currently have my complete car there to have a look at and try to improve the aerodynamics so will see what they come up with.

take off your wing and try to race it...the rear end will be VERY loose, I rember I broke a wing one time during a race and the car was very unstable with out the wing compared to with the wing on...

I'm a little confused. To have good down-force aren't you trying to minimize lift. If the lip on the front/bottom of a wing destroys lift, wouldn't that be a good wing to use? The associated doesn't have that lip, but is still good?
What kind of affect does the rear/top lip on a wing have? I would've thought that this is the part that causes the downforce.
Tx for your time Domit!!!

Without the lip, the airflow follows the curve of the wing surface, accelerating the airflow causing a pressure drop- or downforce.
Yes.

While ideally for the speed range and size a much different airfoil shape is indicated due to the very low reynolds numbers, a "real" airfoil or even a flat (as in constant thickness) curved plate is vastly superior to one that has a protrusion that trips the airflow at the leading edge. Ideally one would want a very thick, heavily cambered airfoil- but that would be heavy and expensive to produce.
