Electric luge - shocking!
Hmmm... I don't know about that electric luge thing. I could understand the reasoning behind taking a two-stroke motor from a dirtbike and strapping onto a luge - but electric engines just aren't exciting enough. Secondly, racing in a velodrome would be dull. Its much more fun crashing into trees and flying off cliffs and stuff.

I just looked at the IGSA newsletter and saw that there are some events called "California Championship Series". What are these events? How much do they cost, etc.? Since I'm in California, these would be relatively easy for me to attend. Where do I get more info?

There is Important news that everyone needs to read at the IGSA site, (gravity-sports.com)
Please click on the flashing link 2002 Newsletter on the front page. Also the new rules have been up on the site for a few weeks now.
The reason that these post’s were posted by IGSA / Bob Ozman is because Marcus is on a road trip with a broken modem on his laptop. This is not an excuse but it is called teamwork.
Anyway I’m getting off this computer tonight to watch the skeleton racing hoping that my dream of street luge could someday become an Olympic sport.

wow! the rumors were true after all, I am guessing declining ratings and expense of securing a separate site was the cause. At least, we still got the gravity games...

In response to the posting earlier today. It is true that Street Luge will not be in the X Games in the future. Marcus has been talking with ESPN on this issue but things had not been finalized yet. Marcus did not want to announce the news until the paperwork was finalized.
The announcement letter went to our web master on Monday and I’m waiting for it to be posted. I was then going to post a link on all of the message boards so everybody could hear it from IGSA. But since someone wanted to post this information before IGSA could, I thought all of you should hear it from IGSA.
When the announcement letter is up on our site I will post the link.

A slight rake has some merit. As air goes under a flat surface, the depth of the "shear layer" of air grows, this is the air that is moving near the luge, but not moving near the ground. Too much rake and air will flow from the sides to fill the vacuum created by the extra space under the rear, this causes a lot of drag. The best is to have a rounded bottom (the luge, not the rider) to get a low cg but avoid a large shear layer underneath, slight rake. I used to use disk brakes but they will lock the wheels and flat spot your tires, or even pop over-inflated pnuematic tires. I use pnuematic drag brakes now.

leo, darren lott mentioned his 'raked' luge in the book saying it's more aero. (but it don't really buy it)

duane, sounds like you want to race!
fyi, Randal has entered in this race in a full fairing(open top) luge, they made him put on brakes, he's got these cute little disk brakes in the backs!

I'd smoke those Sandhill turkeys. They are using pnuematics which are slow compared to good rubber or urethane. Pnuematics can be reasonable fast if pumped up to 200+ psi, which I would bet none of them are doing.

just an idea that crossed my mind, whats the pros and cons of having bigger wheels in the back and smaller wheels at front of an street luge, lets say 101mm abec11 back and 83mm abec11 up front?
would the lower front and higher back enhance the aerodynamics? or i shoudl say the lugedynamics?

Try Louie himself. He's the mad scientist behind the electric skateboards, streetluges, go-karts and dragsters.

So who has the contacts over at Exkate? I know that about a year or so ago, they had several electric luges sitting in the back... what would it take to get a field trip going? HR

hc, I'll see if I can find the pictures of the time that my friend and manager of the Dominguez Hills velodrome towed my streetluge and me around using a motorcycle. It's a cool feeling to have that much traction at over 50mph in a hard turn.
The downside is that you get the occasional arm-stretcher because of the slack created, just like waterskiing.
I think that the electric streetluges on flat tracks or in a velodrome would be a cool new type of racing. It would be silent and so just about any area of any city could have a track.

electric luge racing
http://www.exkate.com/velectric.htm
hmmm, since i am in SJ and there is a velodrome nearby...
we also have an indoor gokart racing here. would be fun to get all the lugers in there for a race.

(thx mat for the tip)

another co. with similar ideas
www.microkart.com (listed as gravity, no info)
I would be interested in just taking engineless gokart down a hill to see what its like.
If anyone have good pics of the insides of gravity formula one vehicles, send them to me.
my wackyboard page has a couple of pics of gf1

thx, chris, i still need to play with wedges, positioning, etc. (riding a haka board with rii flipped, blue/blk bushings, no wedges)
But, for me, there seems to be a night and day difference between the ride quality of a buttboard vs a luge. (marc, our local buttboard pro, seems to be grabbing his pegless luge everytime after he built it couple of month ago.) Also it seems like a luge is actually better for beginners due to its smoother handling.
I'll probably just make a longer and wider buttboard deck next. (a lugeboard?) maybe drop it too.
regarding the steerable luge idea. duane, i was thinking of something cheap and small, like a buttboard with steering control. (anyhow, i want to take a look at that drawing. Also don't those vehicles that you built only go straight. ever bombed those on a curvy road?)
Anyways, just thinking of ways to make the turns more effortless. (this reminds me of hangliding vs gliders, one is controlled by weight shifting (lots of work), the other is all done with a stick.

HC, I'd work the bugs out your buttboard and riding style. Once you get it dialed in, a buttboard is an incredibly fun fast and safe ride. We go between 60 and 70mph without any problems with stability.
I'm not trying to discourage you from other forms of downhill excitement, but give buttboarding a chance.
What do you ride? Concave? Flat? R-II B's? Luge trucks?

I could send you a hand-drawn blow-up of the steering system, very smooth and the mechanical advantage of the steering pivot is the key to smooth steering, and resisting bump steer. No suspension, though, suspensions are for pussies.

hc, I've been building that kind of "luge" for near 20 years. The steering is like a stroker, except the tie rods are connected to a steering pivot, which has two handles attached. Mine are head-first, but the handles can extend backwards from the pivot just as well as forwards. The key is you can dial in and adjust the steering ratio (amount of push / pull on handles to achieve a certain amount of steering). The tie rods have LH / RH thread spherical joints on opposite ends so alignment can be performed without disassembly. Alignment of the wheels is critical. You should plan to have the wheels out wide enough for your legs to fit between, super low. Lots of machining needed to pull this off, can get expensive.
