Default Do "wings" really do anything?

After assembling and running my RC10 B4 a bunch, I was looking at the design. It got me thinking.

Do those rear wings really do anything?

Looking at the B4 rear. The shock towers stick way up above the wing. Then there is the shape of the tower and the shock itself. The shock bodies must really disrupt the air flow.

But there is a small area that is free from all those bits. Is that really enough to do anything?

Then there is the issue of the front shock tower which I would imagine would cause alot of "turbulence". So maybe even that small flat area in the back doesn't get smooth air cause the front shock tower disrupts so much of the air flow?

The wings are just for looks aren't they?

Any Fluid Dynamics Engineers out there?

the wings do help a lot at high speeds 50 and up but at lower speeds the wings are mostly for looks because they don't get enough air flow at normal driving speeds.

no


they are not just for looks, when running a buggy, and jumping it through the air, it keeps the car leval(to a certin degree)

also, as it goes down the straightaway, it keeps the rear more stable as it goes through quicker corners


you would be amazed at what small aero does for the B4, the shock tower does not really get in the way of the air flow at all, unless you are going for the world speed record for a three gear box car.

the car is not punching a big hole in the air, because it is not going above 30 mph, so just where the air goes is the big deal

the car is a great enginered car, fast and easy to drive

if you are going to run the car on oval, then it might need better aerodynamics, but i dont think that is going to happen(excspt here at socal, when they took all the boards of the onroad track and we all took our buggys out there and ran oval)

Contrary to popular misconceptions wings do help ANY size car at ANY speed.

However, one must make the assumption that the wing was designed and installed properly to reap the greatest effect. Even a wing on a HPI Micro RS4 helps, just ask anyone who races them what happens to their handling if the wing falls off.

Same thing holds true for off-road buggies, stadium trucks and anything trying to slice through the air whether on the ground or jumping.

I couldn't of said it better my self.

8th scale offroad is even worse without a wing.

Believe me, it makes a difference. Years ago when I tried off-road, I lost my wing during a heat... The buggy was pretty much undriveable

Default Of course wings help

I race a OFNA Ultra LX PRO at my local hobby store and I tried doing a couple laps without the wing on the buggie and every time I went off the triple the buggie would want to nose dive really hard because of the lack of downforce on the back without the wing being on. So yes wings do help alot depending on the cercomstanses.
