NACA 66 Special A/BGS

Rob,  We used those weld in fitting we reworked the Lakester by installing removable top bars over the eng bay---make sure the car is up to WEIGHT before you weld them and they may still need to be spread or compressed before you can get them to go.  we cut and rewelded them so that when we stepped on the frame we could get them to align..  all and all LOVED how it stiffened the car..

Damn nice fittings, bookmarked the link. That CAD work is sexy as well!~

Not sure just why, but upon viewing the above renderings I have a serious desire to go out and buy some Sreaming Yellow Zonkers and toss my Old Spice in the trash and pick up some English Leather?

Can I get a translation?

Rob I am not an engineer but those upper tubes seem to need a couple of K s in them to me..

  I guess that just goes to prove there is very few things that are new under the sun

Wondering how ya'll figure out the distance between body and rear wheel location and width of the rear envelope. Surface area on the "wing" is what I'm leaning towards but not sure. Is their a major change if they were to be pulled in say a foot or so? Lookin good, glad to see you landed a small sponsor also,
Dan

I think we are about 23 sq ft on the wing area. 3 degee angle of attack. Again, NACA 66-018 on the rear wing also. The wing will also be in ground effect and should double its effectiveness. We hope to average 3000 lbs of downforce from 175 -400 using the flap.

You guys puttin' an American Motors V8 in it???  Maybe Rich would loan you his Packard

You guys are right. There is nothin new under the sun. Our car is just a refinement of what has already been built.
My father in law is 76 and he's says the only real new thing is the electronic solenoid style injection.
Double overhead valves, planetary transmissions, hemi style chambers. These thing go back to at least the twenty's.

Yes, that part is not done yet.

Yes, we planned on doing the same thing. Great minds think alike? LOL.

I was aware of the english leather sponsorship but the screamin yellow zonker sponsorship was news to me.

Rob,
Your Solid Works renderings are sure beautiful and inspiring. Certainly different than my H lead scratchings on some velum that I am doing for my lakester, but we are using pretty much the same shape, NACA 66018 and you have done a couple of things that will probably generate some eraser "swarf" on my drawing tomorrow. What is your design diameter for the main body? looks around 30 inches which would make the length around 166 inches. Keep posting as your car is certainly going to be something to see.

Rex,
I'm flattered. To explain a little more about the fuselage shape, the shape is a loft made from 8 splines. The splines are different on the top vs bottom vs sides to generate the shape that you see here. They are all different percentages of thickness compared to length (with the length all being the same). The thinner bottom splines let us put a little rake into the shape and keep the nose lower. If they just made a taller rear tire, it would help a lot of design problems.
