XRAY - Model racing cars

I agree with Sam in that it is unusual to run more camber front than rear on carpet tracks. You can try Sam's suggestion and if the car starts traction rolling try for instance 1.5 degrees front and 1.5 or 2 degrees rear.

On the downstops I am not sure as it's been a while since I ran pivot ball suspension. It sounds like you are running too much though. For reference let's look at uptravel. If you put the car down with batteries in at rest then uptravel is how far the chassis can pushed upward before the wheels at that end of the car come of the ground. Indoors with rubber tyres I usually aim for something like 2-3mm uptravel at the front and 3-4mm at the rear. If you currently have less you running too much downstop.

You don't indicate the wheelbase, but this is actually quite an important setting. A long wheelbase will result in the type of problem you describe, so you may want to try a 1-2mm shorter wheelbase.

Hope this helps.

The wheelbase which i omitted was shortest setting as the track is technical and on the faster bits i can see the effect of the stability but that never usually bothers me. In any case it was twitchy on the straight with that setting and still had low speed off power problem and so i added some wheel base length and this seemed to actually reduced the problem. ! I think i must have silly rollcenter settings for what i am trying to do. This is with a c-hub setup not pivotball sorry wasn't clear there. The downstop is way too much the whole car is very stable as it has no uptravel and drives similar to a brick with no suspension :/ But i think that is not so much the issue as I can feel this difference ? I am just not sure. Sounds like its not as wrong as I thought !

I will reduce downstop... but with the rollcenter i have the old rollcenter alu bridge so i therefore have four inner settings inner up inner down and outer up and outer down i have this set to be inner down. Closest to the roll center ? (i think)

Camber change is a recent driving this but will try the other way round as its how it should be !
