What does the rear wing actually do?

[Bagman]

At the start of the weekends racing I broke off the rear wing and snapped the mount. Raced the rest of the day with no wing and I'm not actually sure if I noticed a difference. I did at the start over the jumps but I think it was psychological more than anything. I always thought it helped stability over jumps but I'm not 100% sure now and would be grateful for a more expert view.

I'm no expert, but would imagine the wing goes hand in hand with the cars overall aerodynamics - the wing would ensure a good air flow as the car moves and equally would imagine that is there to help with keeping the back end down thus increasing overall top end speed?

In 1/8th scale:

I personally have not run without or broken a wing off when running so cant commend much. I know of a few people that, have and they said and watching the car. It struggle's a lot more on larger jumps, as the wing plays a large roll in car control in the air. And how the car jumps too, At lower speeds you wouldn't notice as much in comparison in fast sections ect. It helps a lot to keep the rear planted to the ground, and will keep the rear more stable. Just generally makes the whole car more stable. But you are right, a fair bit is in the mindset but a lot will depend on the car-the wing that was used.. the speed of the track jumps ect...track high or low grip ect..

Genrale rule of thumb:

Slicker=Less grip track=Larger wings AKA High Downforce
Faster track in general

High Grip=Smaller wing's..standard/low one's
Smaller..slower track


Im sure other's will chime in with more detail

Aids stability when jumping and also provides downforce on high speed corners. The next time you race and you have a fast sweeping corner, try it with and without a rear wing, the rear will try to slide much more when the wing is removed

It means you were driving too slow.

It was a high grip track, 100% carpet. At the same time I was driving slow. I still can't believe that a 1/10th buggy wing provides much more downforce in corners though.

You would be surprised.. yeah on a small high grip track. It wouldn't be such a drastic handling change.. as if it was a large low grip track..

We run a high grip carpet track and frequently have a high speed corner at the end of the straight. This can generally be taken near flat out if you can resist the grip roll.

I broke my rear wing off in one race and then next time I went down the straight the car flew off the track. The downforce at high speed is certainly noticeable!

Don't forget, this is 1/10th scale. The aerodynamic force of an rc car at 20mph is like that of a full sized car doing 200mph.

It's like any other change on your car. Moving a camber link position by 2mm can make a big difference to how it handles. That same difference on a full sized car would be 2cm

I fell foul of a broken wing in our last club league. Leading the final by half a lap when the wing crack and eventually broke off. I definitely noticed it on the sweepers and ended up losing the final as I couldn't carry the speed on the faster bits of the track, I also had to throttle differently in the air to keep the car level, it did feel harder to jump with.

In saying that i do run a 7" wing with a lot of gourney so would have a larger effect consider to a small wing with little or no gourney.
