Team associated trying to break Rc speed record
 

They are shooting towards 200 MPH.

Looks like they signed Nic case, the stream liner looks like the same body shell, color and sponsors. Driveline looks based on the tc5.. But Im not sure how a belt would fare at those rpm's

They should of used maxamps.

:lol:

Whoa, slow down there Tex. They said 200, not 300.

oh snap. You are right. I wasn't thinking when I made the awesome suggestion.

@ snellemin: hehehe...

The end of the clip where the car went flying into the air looked painful.

I noticed that too. It went from being an extremely fast car to a very poorly designed plane very quickly!

No belts just a solid shaft

That link doesn't work for me.

Maybe they should find someone with a clue about aerodynamic and look at real vehicle that run at Bonneville salt flats.That huge front nose must create a huge aerodynamic drag

I was reading an article on Nic Case's work. all of his aero work was done in a wind tunnel.. Front surface area is relatively low. and what little there is has been designed to provide downforce.

What Nic had to say:
Here's his old car.

Im really surprised that he went away from Flight Power to a company that I have never heard of (And i have been around for a while)

I wonder how those cells compare to the FP's

It's an evolution of his first one that was actually very closely modelled on JCB DieselMax that set a new WLSR at Bonneville

The underside of Nics car doesn't show the venturi's as well as the photo above but you can see evidence of them in the photos Ben posted

How do you out-engineer the laws of physics? :lol:

You look at Indy car,F1 and the Bonneville salt flats all those use a front nose like a air plane have the lowest possible amount of aerodynamic drag on the front.Even look at ThrustSSC(worlds fastest car) and you`ll see what I`m trying to say.

Erevocanuk, the problem it that the minute physics of aerodynamics do not scale as perfectly as we thought even ten years ago. That's why F1 has a new variation of their wings and body nearly every year :-)

I think in Nic's design you can see by the open rear section that they are going for a heavy negative pressure under the entire body as opposed to wings and such to create downforce at the cost of high drag.

Yeah, we need to find a way to contact him and get him on the forums :)



The only way to beat the laws of aerodynamics is the beat it senseless with lots of power.. a 1521 and 10s will do that :)

Word!

Nic is already a member here. Just PM him:

Just take a look at the nose on BloodHound SSC:

'tis huge :mdr:

it would make perfect bird kabobs!

So whats the advantage of 4wd over 2wd in this case anyways? It's not like you have to worry about traction as that's really just a downforce/aerodynamics issue..

Im no expert but here is what i think..

You still need to accelerate this car, and 1521 and 10s lipo could easily demolish 2 tires, 4 tires give you that much more bite to get the car moving.. and you dont get downforce without motion.

4wd drive gives you better torque management when accelerating. It also encourages better stability when off power as all wheels have 'drag' which keeps things straight

I would think it would also be a function of radio range also. The car needs to accelerate to 200 within the range of the radio, while a car at Bonneville has miles to reach top speed.

I would imagine the car has less than a mile to go 0 to 200. Pretty hard accel indeed.

I seen this car earlier this year or late last year, supposedly went 165 mph on its maiden voyage. Cool car, I like the more scale or standard looking classes though. more fun and work going fast with limitations

Here is a youtube vid dated sept. 2010 showing a 162mph run

That thing is crazy fast...

The car (the SR 11)
Has been a blast to build, with the help of Curtis Husting. Curtis is very talented, creative - and also happens to be a nice guy.
As you might have guessed - trying to make a wheel-driven R/C car achieve 200mph is very difficult. Over the years, failures have led to successes. Tires, gears, radio range, location, drive-train, traction, aero, set-up, gearing prediction, etc, are All problems that need to be solved… It's a lot of work, but worth it. :yes:

Have a look at vid about success and failure -- http://www.youtube.com/watch?v=OiaPNlR5A4I
