BR's 115th dream

[Guest]

This car is dedicated to my mentor over the past year.

Thanks Stephen.

The name of this car is meant to be purely reverential.



This car will race this month.

I see some good ideas built into this car Joe. Hope she's fast for you.

Interesting concept/tribute car there Joe. The skirting behind the front wheel looks pretty low, does it have the clearance to clear the track's transition area?

I think it could use a bit off that area.

The transition affects the areas in front and behind the car. On the transition, the track is actually further away from the skirts than on the flats.

Very nice Joe!

Which class will you be terrorizing with it?

Thanks Stephen,

This car has been a long time in the finishing, but I gave myself until Monday at noon to get it in the mail.

A few things left to do.

I want to put a Gurney flap on the back.

The black Cheetahs I ordered just came in and they seem much more appropriate for this car.

This car will race in the SS AM

The bar was set kind of high with the name I chose so hopefully it will not disappoint.

Thanks so much for your patience over the past 12 months.

I think I learned more from you in that time than an equivalent time at Parsons.

Best of luck to you this month pal.

Many thanks,
Joe

The gurney flap idea has been bouncing around in my head, i just didn't know the name.

Are you doing top and bottom ?
Do you have a track to test or are you going in blind ?

Hi 3Phase,

I may have time on Easter to test on a track.

I am thinking a piece of 1/16 tungsten welding rod coming off the top trailing edge.

Thanks Eric.

I will stop sanding that area!

Good to know.

Since you are using gurney flap , im guessing you have researched golf balls, turbulators and turbulator tape .

Never thought about tungsten rod, i was thinking the flat toothpicks.

Now I have something to aspire too!

Awesome job Joe!!!

Interesting design, I like it! Your creative mind never sleeps.

I expected something unique from you Joe and you didn't disappoint.

I see your fender philosophy has changed a a lot. Getting more similar to mine.

What is the thinking behind the skirt?

Really? That's cool.

Yes. I like the way you think.

The idea behind the skirt is to stiffen up the body in the one place on the car that will not be subject to wind from the front or the sides.

Hopefully it will be below the rail.

Just a little skin friction is all.

This allowed me to build the middle and front of the body out of balsa wood that is about .06" thick.

Thicker at the front axle area.

What is your philosophy?

Thanks,

That is cool. What kind of flex do you get when you torque/twist the body? Is that pretty stiff?

What is your philosophy?

Well the main similarity is "first, do no harm". Which in this case translates to avoiding the addition of any frontal area. The second similarity is starting at the center of the wheel tread (approximately) and displacing air to both sides as well as to the top/bottom. You've taken that a bit further, even, than I have.

Thanks!

I am honored.

Best of luck with your next race.
