Ok TexasRacer -

It would appear you have a serious problem. Push is caused from the car being too hard at the front or too soft at the rear. The fish-tailing on the sweeper is most likely from the car being too soft or rolling to much.

Can you tell me if you are running any of the sway bars. Running the sway bars will help cure the fish-tailing problem. They will stiffen up the chassis and stop the car rolling about.

With the solid axle in the front you want to run the front end considerably softer than normal. I would suggest changing to grey springs on the front and probably 50 wgt oil in the front shocks.

You have mentioned whether you run foam or rubber tires. If you are running foam try running a shore softer on the front than normal to reduce the push in the slow corners. If running rubber then run the same tires all round.

With the foams, you might actually find that on some surfaces having a harder shore tire on the rear works better.

Try this first and we can start to get the car dialled in.

Move the eyes on the rear sway bar as far back as you can get them. The roll may not be apparent but it is definately there under load in the corner.

What shore foams are you running? And what type?

Try 45 front and 42 rear, that should work good on most tracks.

Thanks,

You are going to get rid of the car because you cant get it to handle right? This is the reason RC cars today have the very sofisticated suspensions, so that they can be set-up for any track and any condition.

IMO, you should either get a front one-way or a front diferential, that will solve a lot of problems. The solid in the fron works, but it requires a different driving style that a lot of people are not used to.

Thanks,

TexasRacer - I was just noticed you live in Austin. Are you racing on the track were the 1:8th on-road World Championships were held in '89/'91? Cant remember exactly which year but I think it was one of those.

That is one big track and would probably suit a really hard set up with a solid rear axle and front one-way.

Possibly brown springs on the front, light green on the rear. 80wgt oil in the front and 50 in the rear with anti-sway bars both at hardest setting and both big spacers in fron of the wishbone for caster angle.

For tyres I would say 45 shore front and 42 shore rear.

Start with 2deg camber on the front and 2.5deg camber on the rear with 0deg toe-in on front and 1.5deg toe-in on the rear.

I would never sell a car because I cant get it set up right. I would perservere until I do so. Changing the car wont cure the problem. All you will be doing is taking the problem with you. I know. I have done this many times. If I cant get a car to handle the way I want it too I now revert back to the factory settings and start again from scratch. I then just make single changes to see whether something works or whether it doesnt. But before I try another set up I always change the first one back to the factory setting. I always note down which changes helped and then once i have everything tried I start putting the different changes together in pairs and then in triples etc until I find the perfect balance.

Give this a try. You will be surprised.
