|  i saw this on xtreme 4x4
i saw a double triangulated 4 link suspension design on xtreme 4x4 where they were putting it on a poison spider tube crawler. i don't know what to think bout it http://i6.photobucket.com/albums/y24...siondesign.bmp take a look and tell me what you think i am thinking of trying this in an upcoming crawler for me b/c it looks like it might be good. any input would be awesome thanks.

Yeah... Like I said, the setup on The 'Tot isn't as drastic as your image or other setups out there. | |

build one and see how the articulation works. thats all we can say. LOL if it works then awsome and if it don't then ohhh well. basicly linking things is simple and very forgiving. allmost any design "works" to some degree.....almost. lol

This setup is to eliminate the use of a track bar....on 1:1 scale crawler.

there is no need for a track bar if you have a 4link and done properly  |

what about the 3 link designs on the 1:1 crawlers that have the thrid link mounted on the bottom links rather than the chassis. What is the point of this and how well would it work on an rc?

A lot of car manu's use a tracbar with a 4 link. I think mainly because they make the links very short. It's true a good 4 link will keep the axle centered with out a tracbar(panhard bar)

Honestly,I feel the car manu's use this set up because it's alot simpler to design and set up. Also the little stright links are easier to work with as far as space under the truck and all the other components. | ||

1:1 crawlers run a 3link with 2 lower links and a wishbone type deal for an upper. Not a setup i've seen too much tho... | |

Yes it does sound like he's describing a radius arm set up. I've seen a few rigs with this design. One that will probly always remain in my mind is Scott Elingers old green Toyota (Rockstomper). He ran radius arm deals front and rear and they did work. Scott will even attest,they aren't the ideal set up but they do get the job done to a certain degree. There are far better set ups IMHO. This radius arm set up requires a trackbar just like a 4 link with no or not enough triangulation. Heres a quick pic of roughly what Scotts links looked like on his. One side had the upper link and the other side only had 1 link. The upper link was only there for keeping the caster and pinion angle right. If you had the upper link on both sides of the axle you would have VERY little if any articulation at all. Also,again,you will have to run a trackbar to keep the axle under the rig. | ||

thx for that info , never had seen a single radius arm setup. My DD has a similar setup but with the upper CA at the frame. I would be interested in seeing how a single radius arm would hold up over time. |

Most 1:1 crawlers I've seen lately use the three link setup, two lower links and a panhard bar, or track bar, whatever you want to call it. It doesn't look like it would work as well as a four link but most all 1:1 competition crawlers I've seen lately use it, even in the rear when they have room for a proper four link setup. David |

Like I said before though,3 links or radius arms do work to a certain degree buuuuut a double triangulated 4 links IS better. If you have the room for it a guys crazy to run a radius arm over a 4 links | |
