1. Less Castor
2. Shorter Wheelbase

And to an extent:

3. Less weight at front (less inertia, makes it more nimble)
4. Stiffer springs (the car reacts quicker)

However:

A). Stiffer springs will give less ultimate grip, more understeer
B). Less weight at the front may also give less grip ultimately
C). With wheelbase its the how that's key! If you could cut a centimetre out of the centre of the chassis then all good, but we do it through moving front/rear axles. That's why I was hesitant to suggest shortening it by moving the front axles back, pushing more weight ahead of the front wheels isn't a good move from prior experience!


When I did 1:1 racing it was easy to tell whether the issue was initial turnin or general front grip, I'm not sure it's so easy with rc. Is it possible it has plenty of initial turn but quickly goes past the max grip at the front then creates understeer?

Sadly, what all that means is if the obvious changes don't help, you may need to actualy go to counterintuitive moves to see if they help!

Oh, forgot the most obvious, a lower front than rear will definitely give a bit more front end!

I get lost with all the camber link stuff sorry, so no idea what all that stuff does!!

Keep working the front changes before going on to the rear to take grip off!
Yes ! - thats exactly what it felt like hence my first post........

As if the turning circle was twice the size it should be.

Maybe with this info someone can chip in and offer some setup tips !

When i watched your car it looked much the same. Your thumbs just managed to live with it that bit better than mine though

It was only the first outing with the car at Worksop. The 511 felt fantastic first time there. Ive never made a high B final there before with any other chassis. In fact i think i was usually around the D in 4WD whereas ive gone backwards from the B in 2WD with the B4FT to the D with the 201

I appreciate that setup cant make up for skill with the thumbs and there are guys there with far more talent than i, it would just be nice to get it feeling similar to drive there to how my B4 did. Right now im kind of regretting selling it !

Anyway, cheers for the info guys, the fog has cleared a little though not completely.
