I run currently outdoor with foams on a good grip bumpy asphalt track.
Actually, on my track, the cars to beat are Pro4's...
Thank you in advance to all gurus of 415....
I've ordered from Steve, the new DJ suspension module... what do you think David ? it can give appreciable help with foams outdoor ?
Or I was hurried ....?

Bye.

I think David has already addressed this. I believe he said that the DJ Suspenion is for Rubber on Asphalt. It only back a page or 2 chek it out.

EJ, if you are in Singapore make sure you stop by Katong and grab a bowl of laksa noodle soup. It is very tasty and you can'y get it as good outside Singapore.

January I landed in Singapore. You could see a very nice off road track on aproach. Too bad I couldn't stay longer.

A picture with your post, when trouble shooting, will probably get more rctech help than without...

The effect of lowering the upper link and what it does to the roll center depends on the suspension geometry of the vehicle. In the case of the 415 and Evo IV, lowering the inside upper link lowers the roll center. Basically, if you were to raise the suspension blocks to the point in which the suspension arm were sloped downward to the wheels and that was your static position, then yes, lowering the inside upper link would raise the roll center. I have seen illustrations of roll center points but some of these illustrations donít always depict a typical R/C cars suspension so although they are accurate for the geometry in the illustration, they donít always apply to all geometries.

Regarding camber change and roll centers, they are both related to one another and in my opinion, equally important.

Thanks for the warm welcome. Iím glad if Iím able to assist in any way. Iím not always able to be online so I apologize in advance if I donít reply right away.
Very true about the effect, but I have in front of me the modelisation of the suspension of the 415 with the LW suspension, and if i lower the camber link as specified, i raise the RC. That's even if the arms are making a V when the car has 5mm ride height. So, unless you have changed the geometry of the rear hubs or use a very high roll centre, I don't see what you say apply to our case.

If I change the geometry so that the arms are sloped downwwards to the wheels as you said, then indeed lowering the inner camber link will lower the roll centre aswell.

Anyway, can't wait to have the suspension in action

I agree with TRF415boy. Since David posted that, I've been trying to reconcile it, but I can't. If the inner link is raised, it lowers roll center, and if it is lowered, it raises roll center, that's the only way I can see it happening.

It seems with the lower arms angled up slightly, the effect of spacers under the upper link is minimal to overall roll center, compared to if the arms were angled down towards the wheels. The intersection point is much farther removed from the car with arms angled up to the wheels.

My own setup testing (though I could be fooling myself), shows that more spacers under the inner link increases grip on that end. On the rear, spacers under the hub ball stud seems to decrease grip. By Davids explaination, spacers under the hub ball stud, and none under inner ball stud would lower roll center, and increase grip.

David, is there something we are missing here?

Mike
