XRAY - Model racing cars

Hi,

On some corners on and off throttle I could do with more turn in, my car seems to go a little wide out of the corner mor so on tighter corner and when it's going slower. I'm pretty much using the standard kit set up. Would H1 & H2 roll centres on the front help ? what about them on the back ?

Thanks.

I suggest that you use the H1+H2 roll centres both front and rear to have more chassis roll and more turn-in.

Or you can keep the standard roll centers on the rear and use H1+H2 front, and raisen your lower roll centres on the suspension arms, by adding shims under your suspension mounts (0.5mm) but this is a very aggressive setting.

There are numerous changes which will help for mid corner steering.

- softer front spring

- thicker rear swaybar

- front anti-dive

- less rear toe-in

- add shims under the outside of the front upper link

- front diff in low position

- more front downtravel

- weight bias more towards the front

These are the main changes that I could think of. My local track has many slow, tight corners, and there, my car works very well with a front gear diff. I use rubber cleaning gum inside the diff (which is used for nitro), so almost solid. But this really gives a lot of mid corner rotation.

Alexander, what about using 6° "C"? Car should be less aggressive entering corner but smoot and faster in middle part and exit, right?
About antidive, which size for steps? 0,5 shims?

Thank you

I have been testing a bit with 6 degrees lately. This makes entry smoother and a little more on-power steering. It actually works quite well but depends on the track layout.
