I think a DWS with a drop between the two wheels is a balance of both forces.

Sugar Creek Racing"I'm actually working on a design that utilizes the tear drop with standard wheels. Picture a catamaran with the tear drop as the axle cross bars." How far along are you? I have drawn and attempted something like you are describing. So, far I have been unable to complete with my expertise and equipment. But, I do think the idea has great potential. Eagle , I tend to be one of those people who have things do laps in my head for a long time and then it falls out on the work bench over a short period of time. I’ve mainly been developing weight placement plans so far and have figured out how to put the weights into the tear drop sections if needed. I’m planning to put as much of the weights as possible into the “sponsons” and the rear wheels. I do not think I will need to put much weight in the axle spars if my plans work out the way I see them in my head. I’m also planning to go back to the vacuum forming that I was playing with before MA. The fenders will be kind of a space frame with a vacuum formed skin. As soon as I get some sketches further along I will share them here.

Sugar Creek Racing:I did a car and buried tungsten in the lower part of the fenders. It was a lot of work. It broke track record at district 3 times. But, at MA it took 40th. My oldest daughter insisted that it run on graphite and that I not make changes. I added clear tape, but when I got it back much of the tape was gone.
I look forward to seeing design. And, I really look forward to learning more about the vacuum forming. I remember other pictures you posted. But, I have no idea how you get from your molds to the piece, what the final piece finish is like, how the weight compares to other options, or how easy it is to do. But, it is cool that you can easily recreate if it is a design that works.

Just had a crazy thought about the turbulence that happens behind a flat tailed car. Real cars use a spoiler to fix that some, but that creates down force which we don't want. However, some Drag cars use a flat spoiler that changes the air flow without down force and I think gets rid of the turbulence by creating a void.
Could be an interesting experiment for someone that has a track to test for any changes in speed.

Side view sketch for the car. Picture two torpedo levels joined by the teardrop axles.
For some reason, the picture is importing upside down. Is there a way to spin an attachment in this forum??

I know it is rough but it was a concept vehicle.

Chuy: Is this a clear (poured) body sitting on top of a unique frame?

It is actually a vacuum formed polycarb body over a skeleton frame.

Thought I posted this the other night, but not seeing it. Another Wild idea in racing.

Definitely not a scout car. With the exception of the guide pin (not sure why you would need a guide pin and a wheel), the razor fronts, and the extra long rear fenders - I have this car on my desk.
I was afraid to go any narrower on the front (due to handling -worried about keeping alignment). But, I might attempt if one piece axle for both front wheels. Same handling worry for rear fenders(plus no stop section). And, of course, no razor wheels in Scouts.

Thinking guide pin would have less drag on the rail and car would require less steer maybe. Long fenders are for two ideas, one being able to knife edge them at a shallow angle and maybe putting weight in the fender base for lower center of gravity. Yes, one piece front axle with a Steering bend on one side. the general idea of the whole car to to put as much mass as possible in the rear and the lease air drag in the front ... and look cool

If I figure out how to put pics up here I'll post up the one I'm painting when it is done.
If you want to PM me your email and/or cell number I can do it sooner.
I think we are going to call it Aero. Nothing is ever final around here, but that was the general conciseness when we laid out the paint scheme last eve. It was a bear to tape. And, the tape leaked in some spots. Will have to see how the next stage covers in a couple days. Next time I will also likely have to invest in some sealer. The built in weight is still showing after tons of work. Its what I call modeling. Because the same thing happens when I do my customizing on model cars. I do not know the official term shrinkage maybe. The solvents or something interact different with the different materials even if the body work is perfect.
