Traction Rolling - how to solve it
#17
I agree i believe in your set up workbench for the phone that it goes into explaining very very many things, and it is very helpful and I have learned A LOT of things, and i am very appreciative that you have made this app, i agree with the track with width suggestion, and so does your app somewhere in there it says something along the lines "to reduce traction rolling increase track width"

Hi Martin, good luck with the full scale racing.
I typically increase track width if possible then increase the roll center to reduce the amount of roll and adjust (soften) suspension to suit.

.... Also when I crashed during the last race this past season while trying to make an outside pass in corner 2 at mosport, it is not just my pride that gets hurt. I hit the tire barrier at about 150k kms flew up in the air and broke a couple of ribs in the process. Much less pain and cost when you wreck an RC car
....So.... what you are saying is, contrary to belief, traction rolls also occur in 1:1 cars too, its just that the tires involved in producing the traction roll are not the four on the car itself

Ouch. Glad to hear you seem to be ok now and have a sense of humor about it !

Plus, I always hear about how it's best to avoid certain chassis because they flex too much and thus produce too much traction for medium to high grip carpet tracks. How come people don't just opt to run these cars, but go really light on the traction compound? So instead of doping for 10 minutes, why not just dope for 3 minutes and let the car's natural grip compensate for the reduction in rubber-delivered traction?

The physics involved is you dramaticaly lowered the center of gravity and altered the balance of your car. So with a given setup, the suspension had to work more to transfer the additional weight. Also that weight was added as low as possible thus making it harder for one side or the other to lift.
As basic as it can be described you changed the amount of force required to lift a weight on a simple lever with the fulcrum being the wheels.

Sorry to hear about your accident Martin.... Real Car races are too dangerous for my liking, and I drive too many cars anyway(100+ per day for the last 18years).... Rc works way better... Hope you'll Rc race again...

I have tried that high roll center soft spring approach and found it actually made the car traction roll more because it does not allow the car to roll into the carpet enough and tends to jack itself up causing a traction roll. I found that softer springs and lower roll centers tend to work well. But there are so many variables you need to experiment to see what works.

I too have your app on my iPhone. I couldn't find it for a while for some reason but glad its back now!! Brilliant app and for the amount of info within is very cheap... Thanks also for the blog entries which are very helpful reads!
