http://www.youtube.com/watch?v=eN9Cvo6Sn0Q I think this vid shows a droop working properly...watch the breakover about :32 into the vid, as the skid high-centers on the rock the droop set-up allows the front wheels to maintain traction. I don't think you can get the same effect running a conventional sprung suspension. But, I could be wrong :-P After all, I'm a just a noob BTW, I've really enjoyed this thread...very informative and productive discussions like this are what makes this forum worth reading every day. | |

back to the oil weight......... i have read every thread about droop vs. sprung, im with R2J i just want under stand it. i have been messing around with kind of super thick oil (i read that JFA was running 1000wt in one of his rigs and he liked it) to see how the suspention reacts. THE RAMBLING IS ABOUT TO START try to keep up......well in some rocky places the thick oil works very well due to the slow reacting axle, front right tire on top of a rock then the left starts coming up, the right will stay in the air for a second longer when the left hits the top of a rock and the right will set its self down on top of another rock if you work it with the throttle. but now i have seen something like this with sprung suspention also but the tire does not sty in the air as long. RAMBLING OVER. SO.... the way i under stand this is with a droop set up (no springs in side) your cassis is what makes it settle to its ride height. so a lighter chassis does not work as good as one with more weight. these are what effects the pressure on the tires. sprung suspention chassis' weight has little effect on the articulation of the suspention. all of the tire pressure on the ground comes from the springs. |

i have seen on some of the comp videos trucks (droop and sprung) navigate the same rocks and they both look the same........ i dont know any more. i did jump on the droop band wagon (i made 4 tubers 3 2.2 and a super all of them droop) but now im not so sure. on some rocks the droop works better and on some rocks the sprung truck works better. i dont know......... 9 of one and 3/4 of a dozen of another YES..... i like this thread too. | |

Cubed.. makes sense. I was just looking at my TLT and there's no way it should weigh 500lbs... |

Does anyone have a Video of one that can droop like the Above video and still carry a Tire? I can't see how it could carry a tire like a Torsion Set and still Droop that much. Doesn't seem possible.

It will "carry" the tire if the hole is deep enough or the oil is thick enough. You cant have lots of articulation and have it act like a torsion too, but you can set it up for any amount of articulation that you want.

So if you can carry a Tire like a Torsion Chassis. Will it still Droop like that Video? Or does the thicker oil slow down the reaction of the droop to Carry the tire longer before it droops. Does that make since? I swear I'm not retarded......Just seems to be a lot of I'm not sure how it works answers. Thats all. I think this helps to get to the bottom of how it really works. |

The thick oil will allow it to carry a tire over a hole. It slows down everything though so you would have to drive slower over a break over angle rock.

I like this droop idea. I'm currently building a TXT tuber but I think instead of building with conventional extended shocks, I'm going to build on the bumpstops and set the shocks up for a "retracting" spring. The shocks are 6.25" long Aluminum Savage shocks.. should work well for this setup.

I know i'm learning alot about how to set my hustler up , I have tried NO springs in the front , and the thickest oil I had at teh time which was 80 weight in the rear. I totally understand what rockpiledriver is talking about. Testing the same thing here. Quote:

r2j...Maybe I'm way off base here (noob, remember) but I believe that the way in which the vehicle weight transfers is what makes the difference. I "believe" that there IS a difference between dropping only the axle on a break-over, and shifting the entire vehicle weight. (as would occur with a sprung set-up) Also remember that a droop rig set-up (properly) will have a lower COG. (I know there has been disagreement on this) Question for you: Why (or) do you feel there is an advantage to carrying a wheel ? Wouldn't it be advantageous to keep as many wheels in contact with the ground as possible ? Just wondering here..... |

Carrying wheels gets you over cracks.

example of where carrying a tire would have helped. |

I don't think calling it.. Lower COG is the right term. I'd say more of a way to counter act rigs with a Higher COG... I say that b/c the springs help keep shocks closed. You still have that the weight in the same spots. I have seen many Sprung rigs with Flat Lower links just like Droop set ups have. And I have seen a few Droop set ups not have there lower links flat. | |

Run why do you keep saying a tuber has a higher CG than a TVP style truck? I just don't see how the comp tubers of today can. Last edited by Cole82; 05-28-2007 at 03:28 PM. |

| B/c Steal tubing and Brazed Joints Out weigh most TVP chassis....Look at XRC and the SW3....They have less material up high and it's aluminum not steal tubing...I'm sure it's not much. But with bigger Tubers like with a Super Class rig. The SW3 and XRC would have less weight in it.

A stock rubi body weighs over 6 onces wich probably is more than the xrc itself. Now you just flipped the weight from low to high. The hustler has a very minimal cage up top that I would bet weighs less than a leaxn body. | |
