| link question Can anyone tell me what it does when you raise/ lower the links on the chassis? What happens when you move the link mounting locations on the chassis closer together? I am just trying to understand what the affects are of moving the links to different mounting locations on the chassis. What does it do to move the links on the axles to the center like on the clod as opposed to further out. Less stable I assume, but better for crawling? Thanks guys. |

raisisng the lower links on the chassis will give it more rear steer (BAD) will also give more antisquat (but with the little crawlers its hard to tell a difference if you run 50% squat or 150%) so squat really has nothing to do with it making the lower link mounting points on the chassis closer together will give u less rear steer (good) i didnt get ur last question hth |

Raising or lowering the upper or lower links will change the squat/anti-squat effect along with the roll axis. If I understand your last question currectly, your talking about moving the upper links towards the center of the axle. This will provide more lateral support and keep the axle centered in the chassis. The set-up may not seem as critical with the little rc's, but I can tell you, when you do have a currectly set-up 4-link, (like 3% to 5% anti-squat, 3 to 7 degree down roll axis, lower links with 5 to 10 degree up and uppers at 70% of the length and angled currently for centering the axle) your little rc will crawl like crazy. You will be able to control you rc better, it will steer where you want it, not where the axles steer it. Roll overs will happen much slower and you will have a better chance of driving out of bad situations. It may not be important for bashing, but if you really what to build a sweet crawler, it will matter a lot.

Thanks guys. That is exactly what I was looking for. Sorry my last question wasnt clear, but Trailer you answered it. From what I can tell from reading the boards you want at least 17" wheel base? Which is better, a standard mounted shock or a cantilever system. I am working with a Jugg2 with the full ESP kit and a TXT-1. Bothe are brand new and have been shelf queens for over 2 years. I am just looking to do something with them. Thanks Jason |

I think standard mounted shocks are the way to go, I don't think cants. work as well.

| Concerning the mounting holes on the chassis for the upper and lower link, should the top be directly above the lower? What happens if the upper mount is closer to the axle? Thanks Sorry for the dumb questions, just trying to understand this. |

Just a couple tips from 1:1 crawling that I use when building my rc crawlers and they do very well. Oh, and these aren't dumb questions, a properly set-up 4-link is not that easy to understand, there are just tons of different factors. Last edited by Trailerguy; 09-30-2005 at 03:51 PM. | |

rear steer is determined buy your roll axis angle not the length of your links you could make ur upper links longer then your lowers if u want |

You are currect, the axle steer is determined by the roll axis angle, but if your lowers are angled less than your uppers, then the uppers need to be shorter to help compinsate for it. Plus if your uppers are really long, then you have less angle on them. And with less angle on them, the links have less controll on placement of the axle under the chassis. | |

And, no, I don't believe you were owned. No one can be owned when it comes to building suspension, too many ways of doing it and having it work. | |

if ur upper links intersect at the exact same spot wether there 2 inches or 10inhes long you will have th exact same roll axis correct? there for the exact same amount of rear steer whether there 2 inches or 10inches long? |

im not saying i am goin to do that i was just putting the point across that there is no magic number and that you can make your upperlinks longer then your lowers u dont have to have the 70% rule and in answer to this question Concerning the mounting holes on the chassis for the upper and lower link, should the top be directly above the lower? What happens if the upper mount is closer to the axle? there will be no ill effects on my rc my lower links are around 1" futher forward then the uppers on the chassis and on the diff the uppers are around 1" futher back my upper and lower links are the same length it seems to work very well my roll axis is flat (it actually slopes down a tiny bit to the front)on the rear diff) and my squat is just a bit under 100% |
