Default Hmmmm does anybody know the effect of....

Using an oring on the shock shaft? its on the xray set up sheet and im not sure what it does or when to use it! im guessing it acts as a limiter so the car doesnt lean as much, any input would be great

erm i have read the manual and it wasnt mentioned other wise i wouldnt have asked on a forum dedicated to sharing information
ive just been been told that its a tuning option often used on very smooth wide tracks were soft springs are used to keep the car flatter whilst cornering by reducing how far the shock can compress.

It lessens the ride-height and also softens the impact when the shock is extended to it's maximum.

I think it is meant to be used on shaft outside the shock body, to limit up travel. If you were to put it on the inside of an XRay shock body, it would prevent you from opening/closing piston holes.

I don't know anyone who uses o-rings inside shocks to lower ride height. That's what spring collars are for.

If you're going to claim to be "theDr", I suggest you learn more about chassis setup before posting.

yeah man, no point trying to be a smartass when your very own logic is flawed.

I don't think anyone has given you an answer yet, too bothered with arguing amongst themselves, so I will.

O-rings on the shaft outside would be a bump-stop, to limit compression travel. It is not something I have ever seen seriously used in RC although they are common in full-size motorsport.

Ideally, you should only use a bumpstop to stop the chassis from bottoming out over the biggest bumps and kerbs. If the car rides on the bumpstop in normal running, you will lose a huge amount of grip because the suspension will effectively run out of travel.

Another reason to run bumpstops is to stop the driveshafts from popping out or similar issues, I know that with my old, old HPI Pro3 I had to run quite a few o-rings on the shaft otherwise the driveshafts would pop out in crashes.

Hope that helps.

KA-POW right back!

Besides, anyone who uses the word "whilst" (properly no less) should be welcomed with open arms.

Some of you guys are cracking me up! Xraycerboy is simply asking for help. If he wants to have his user name rated/critisized I'm sure he would of started a thread on the subject.

Xraycerboy welcome to the forums. Most of the time guys are friendly and helpful as you have now seen! If you are new to R/C cars then you will enjoy running them. If you are just new to the forums, then don't worry too much about wise cracks. We all get them or direct them once in a while. Just not so many, one after the other.
