Wing kits . 40$


Recommended Posts

 Interest  checking for  high mount rear wing kits. It should be about 40$  plus shipping.  Reply here . 

 The Kit will include the foam cores  @ 72x15in and be split for the spar.  You will have to build the spar and cover the wing with fiberglass cloth/paint.

 If we get enough interest we could build them complete for 200$.

What do you mean "Split for the spar"?

 

What airfoil will you be using?

 

Any reason to use such a large spar?  Why a rectangular spar?

 

Pictures?

 

I Just built one, so this process is fresh in my mind.  For just the airfoil (no uprights, end plates, etc) I am in for $200 (Foam core, Fiberglass + Epoxy, Mounting Bosses)

 

I would consider building another for my 2nd car.

Here is a tip for anyone looking to laminate a foam core. These are woven sleeves like a Chinese finger cuff, you kind of scrunch them up and slide over the core then start in the middle and as you pull the weave out towards the end it will shrink down and lock in place tightly over the foam core. Just use as many layers as you need to get the needed strength.

That is diameter, a long thin wing profile would be nowhere near circular in shape. I can lay out a wing profile and get the perimeter and convert it to an equivalent diameter really easy in CAD. Plus the way these sleeves work they can expand or contract probably 2X at least their rated diameter.

Back in my day, all this aluminum was only 170 points!

 

 

 

OK, so Klaatu's diffuser is probably only ~30 points under the current rules.  Still far too much - diffusers are very points inefficient.  And if you look closely at our car, it already has a zero-point diffuser. Just not as pretty and efficient as we'd like.  Maybe it will get adjusted in the future :)

Just call it a "Rear Splitter"
