You can limit the articulation the same way with either a Sprung or Droop set up. A Zip tie and a Winch would do the same things. Ones not any easier then the other as that goes. Know with a torsion it is harder to do so. It takes more time to dial in things like that on a Torsion chassis. Weight comes into play alot more on a Torsion chassis then any other chassis out. Suspension does have alot to do with Crawling. But weight and balance is a big factor as well. Force on Tires is always important. It can mean the difference from lifting a tire or not. From getting traction to not. Now how does a Droop set up work and Why? Doesn't the shock always want to stay closed. So then it would always pull up a little on the tire. What would make it better then a normal 4 link and Sprung set up? Whats the Disadvantages and Advantages? The way a suspension works, the Force thats applied and the Roll Center are all very important and have been brought up. But how do they factor between the two designs? | |

To sum up my understanding of droop, when your crawler wants to articulate, it dosent have to fight the spring, using a small internal spring allows it to "act" like a shock but but not fight the articulation. The big advantage is you have WAY more adjustability than spring. It seems like you need to set up a REAL rig with droop, learn how and why it works and then get back to this discussion, its like bringing a knife to a gun fight, but once you do your own evaluations instead of assumtions, you would understand where the "DROOPIES" are coming from. BTW, I dont mean to hack when I say "Stick" I just never believed in them, no matter how well they do. ~John |

John, The only reason I brought the torsion chassis into this discussion is that in my opinion it's performance would be closer to a droop set-up then to a sprung set-up, that is all. |

A torsion chassis uses it's whole chassis as it works across the rocks. The others Droop, Sprung what ever use the shocks to control everything. | |

OK now your on 1:1, I know your trying to compare the two, but like you said eairlier, their different, way different, the weight ratio can not be compared/converted to scale. So what I know of droop in r/c (and I am no expert) is that you can limit up/down travel alot faster and adjustability is more precise than a spring setup, no matter how soft of a spring you use. And the knife to a gun fight thing was in referrence to r/c suspension, not 1:1, you may be an expert at that but were talking r/c. ~John Last edited by KRAWLR4life; 05-25-2007 at 12:35 PM. |

This as gotten way out of hand. None of the questions on how it works and why are being answered. Everything keeps getting the run around and pawned off and compaired to a Torsion chassis. Can someone please tell me why it works so good and that the internal spring on the shocks helps more then just keeping the chassis low? Thats all I'm wainting to figure out. |

Without springs, the right side of the truck fully extends, raising your COG. Also the springs keep the shocks from unloading on side hills. For the most part I really do not know the physics behind why droop works for me, but it does what I want it too. If you are curious about it, build a droop rig and try it. The torsion is only being tossed in I think, because it is also unsprung. Though I wouldn't compare them my self. |

| No, start off with the softest spring known to man, add zip ties or clips and its only going to get stiffer, now take the spring off, now you have a floppy suspension, you can either stiffen a little or alot, you can make it travel 1/4 inch or travel to 3 inch, with a srung shock, you have to take it apart, put fuel tubing or like type spacer, blah blah blah. Anyway, just build one then evaluate. ~John |

On a sprung rig you don't have to take the shock apart to limit it's up travel. You just take the bottom heim joint off and put a spacer on the shaft. To limit down travel just had a Limiting strap. Where would you put a Spacer on a Droop set up? If you put a spacer on the inside that just shorten the down travel. If you put the spacer on the outside on the shocks shaft thats like giving it a lift. But would put more tension on the internal spring. | |

Droop can be built to sit lower, but have the same break over angle because the axles are able to drop when the belly gets high centered. Most droop setups are belly draggers.

See around here we also have many different type of rocks and inclines. Capen, Cosmo, Disney. Are all complete different rocks. I get into these things sometimes. I try to stay out of them. Just because I get worked up to much. | |
