Status: offline 		At very high speeds, probably. But just driving around at low speeds without a wing you will notice no difference. This helps explain the concepts of a wing. http://www.oneshift.com/articles/article.php?artid=34&pageid=1&view=1 . I'm a college student and to me this seems like very interesting experiment as to when the affects of a wing actually come into play. More then likely it will be at speeds well beyond your truggy or buggy.

Well, I havn't tested it but, it doesn't take much air flow over a wing to create lift or drag, just throw paper airplane to see that.

I think the wing helps protect the truck when it flips and helps the truck from fliping backwards to easly

Status: offline 		Back in the day we used to experiment with this all the time, and the conclusion we reached over and over and over and over again was that yes a wing makes a huge difference. Of course, more so at high speeds but also at slower speeds. The thing you need to add into your thoughts regarding the issue is that I think you're forgetting to factor in the scale speed these cars are traveling. In 1/10th scale, a RC car traveling at even 10pmh is actually going 100mph in scale speed. So your 50mph question is actually about a car traveling 500mph. Do the math and it'll open your eyes to why they work, why they're on so many RC cars, and why they are a so neccessary part of a successfull racing program and running of any RC car.

I belive the rotation of the tires overtakes any affect the wing has in the air,

How the truck leaves the ramp and how its angled in the air all have to do with when I release the throttle off the jump,

Status: offline 		If they didn't work I would think they wouldn't be on any RC racers and the pros would be the first to go wingless. But since so many of them hotshots use them, and so many kits come with them, it seems they have to be of some benefit.

Status: offline 		Wings most definitely DO help. Even if its just in crashes! The added downforce is also noticeable on the track. However one cannot compare scale speeds, as you cannot scale time.

Status: offline 		If you scaled time you'd have the same relative registered speed and thus aerodynamic aids would be irrelevant and no one would use them and you could just as easily use a cardboard box in place of a touring car body and acheive the same results.

I'm not entirely sure what this is supposed to mean. Time and aerodynamics are two totally separate variables. I was only trying to point out that simply multiplying speed by scale ratio is not accurate. The only way that would be possible would be to also scale every other relative factor - Dynamic Similitude. Geometric similitude can be matched, but kinetic similitude cannot.

There is no question that one could take an R/C wing into a wind tunnel and make accurate calculations on the amount of downforce that is applied given a certain speed. But time is a component in measuring speed, and realistically cannot be scaled. Same with air molecules and other factors that WOULD go into calculating aerodynamics.

I'm also not saying that the relativistic speed in R/C's isn't greater than full scale, just that the mathematics are much more complicated than simple multiplication.

Status: offline 		All I was saying was that if you did a 1:1 equation relative to time and speed that you'd be back to the same old thing of saying the car is only going 20mph, which if it was then aero wouldn't matter and you could run a box for a body.
While you're correct that there are more complicated theories and equations need to be involved to get a true scaled speed equation it seems a little much and likely too hard to come up with. I guess all I was saying was that I to an extent agreed with the earlier poster that suggested that scale speed was relative. Because if they weren't areodynamics wouldn't play a part at all in our hobby. I just tend to look at it all in a more simplified, understandable way I guess as far as trying to relate it to others.

Status: offline 		You can tell the guys that race and the ones that dont..The ones that dont race..naw you dont need a wing..the guys that do race KNOW that a wing works..even on a small track..contrary to popular belief the top pros are not going to put something on their buggies and truggies that does not have a purpose..so "if" they dont work why do the top pros use them?

Status: online 		ok, back on subject, like Rob said, the wing helps a ton in a crash, plus it makes your car look cool, acts as more area for stickers and helps protect the cooling head on the engine
