Long shot but looking at getting into gravity racing does anyone know of a vehicle for sale.
Thanks Matty

no, but had you thought of a kite buggy,.... this sort of thing here

no brakes, but that can't be beyond the wit of man,..

Oo I built one of these for the GFS with my last company.
Scary how fast they go, haven't got one for sale though!
If you need any tips shout.

I have one I've used at Belchford, but since this was the last year for that event, I may be getting rid soon. We ran as team 'in last place' team 40 - there's a photo at http://www.mgcars.org.uk/mgcclincolnshirecentre/Pages/2011%20Gravity%20Racing.htm - you can see the 40 on the front. To me half the fun is in coming up with a design and building it. Our design looks pretty crude, but we still finished 21st of 45 starters, despite a 10 second slower run when Dave span it in the chicaine and buckled the front wheel. We ran the next 2 runs with brakes on just 3 wheels as the disk from the buckled one didnt fit the spare wheel we borrowed. I had the first of those runs, and we literally got the wheel on and straight to the start line and off - first application of the brakes was pretty exciting! No need to steer into the chicaine as the whole thing jinked 4ft sideways and took me through anyway. We were in our second 'shakedown' year, then we were going to go for the novelty entries which isn't quite so fast anyway, hence the odd looking frame to give something to attach a body to!
Regards
Hugh

This was our bad boy, shame its probably sat gathering dust in some hanger in farnborough, had a uniques suspension system that had no springs and damper which evenly loaded each wheel and allowed them to track uneven ground nicely, no pitch or roll either!

I've thought about this a bit. Got a design in my head that has tennis balls as suspension which i think could work quite nicely.

Got a variation design that uses bike wheels and canters the wheel over for the corner so the forces are going in the right direction and there is reduced risk of the wheel buckling.

we made our own wheel hubs that were wider giving the wheel more strength against lateral loads

is there anything in the rules to say you can't use a roller suit?....

People do occasionally sell them. The best places to look are on the Scottish Cartie Association web site and the UKGSA Forum.

I think this one is still available.
