Default Sedan diffusers

With todays narrow nitro sedan chassis plates, I'm not sure how much good a rear diffuser would do. Most rear diffusers would probably work very well on cars with large chassis plates. Maybe I'm off base here.

You are correct about the chassis plates, but ideal design of a wider chassis would be nice, however with the narrow chassis of today's designs, I addressed that issue to funnel what little air that does go under the chassis directly and make the most of it by giving the diffuser an hour glass shape to create as much vacume as possible.

Interesting to see if you bring your design to market.

Most cars went to narrow chassis designs to limit weight, and to center more of the weight to the center of the car. With Lipo batteries saving almost 60 to 80g's of weight and much lighter drivetrain and suspension parts, it would be interesting to see what a full chassis with aero package would bring to the table. One of the best older handling cars on the mkt was the NTC3. Unfortunately reliability of drive train was always an issue with them. The large chassis plate of the NTC3 probably helped to limit underside aero drag that the current cars possess. The larger chassis plate also helps settle mid-corner aero problems with cross air underneath the car.

Thank you......

I've been working on some other items and got side-tracked from working more on this.


After a lot of thought, I see no reason to bring this to market for 2 reasons.....first, I don' t have the money to get things started, and second, although I see this as being a good selling item, I don't think that I would make back the money needed to cover the cost of the inital investment within a reasonable amount of time. so....I'm going to be showing you all how to make one of your own rear diffusers. It will take about 30 min to make.
I will post step by step instructions later this week.

hey rcfoolz ! Good thread and idea. I come from electric and my pal and I would like to test your diffuser on our touring cars, your project brought tons of discussions(/debate/fight/murder ;-) on the table . Could you decribe a brief how-to ?

.................Why don't you sell detail plans with clear photographs and diagrams on how to make the aero package?? I would buy the plans, at least that way you would be about to get some money for your ideas and hard work.

rcfoolz, did you give up on this? I was thinking of doing something similar myself.
