Understeer/Oversteer??
Here's poll for those with finished cars. I'm curious as to whether the Locost has any innate handling tendencies that should considered
in the planning stage (anything to avoid actually building a car  ). Or, is the design basically balanced and can go either way depending on small
variations in setup?
Please feel welcome to add comments on your tires, springing, use of anti-roll bars, wheel alignment, or anything else that may be affecting your
handling.
Would you say that your car:

165/65 x 13 tyres with 22psi both ends very controllable and gradual breakaway at the back.
yours, Pete.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Unfortunately the handling characteristics of the car can vary (or be altered) enormously with relatively small adjustments and differences in
set-up.
Bumpsteer is probably the bugbear to try and reduce as far as possible, but it will never be perfect......
Just far too many variables to draw any sound conclusions IMHO, the differences between each car and it's effects are infinate.
Dont just build it.....make it!

agree with stu16v here,transformed mine from a bucking bronco to a reasonable ride with fantastic grip with a twiddle of the camber and tyre
pressures

I thoroughly agree with you, Stu, the cars are like snowflakes 
Interesting, though, that the few answers so far point to very neutral handling with just a touch of oversteer.
I've been doing some reading about 'roll couple', or percentage of front to total roll resistance. For example, this chart
(http://users.erols.com/mathewg/mgcudah) claims that a car with a 50/50 weight distribution would need over 86% of its roll resistance in
the front end for neutral handling.
Anyway, I calculated a roll couple on one Locost having a 46/54 weight distribution to be about 60%, which would indicate extreme oversteer.
Wrong!
Maybe the apparent discrepancy is due to the data being based on cars with big V8's hung out the front.
Thanks, gents, for responding to my question. I should have posted it to the Finished Cars section, but I get the impression that everybody here
reads everything anyway
BTW, I envy you guys with your cars. I haven't even seen one with my own eyes yet!

oversteer........the more i press the gas button the more it seems to do it.
understeer as never shown its self, all joking aside oversteer is usually driver induced.

Under steer, oversteer, Wombling free.....
You need to be a certain age to appreciate.

That's a good thing. The more adjustability built into a Locost, the easier it will be to correct any inherent shortcomings.
Cheers, Rorty.
