| 26 degrees according to the angle finder on my phone 20 ga Not good. I pretty much had no clue what was going on with the truck the entire day. Finished 35th out of 72. Only finished 2 courses Last edited by Nabil; 11-12-2011 at 04:50 PM. |

So how do you like it compared to your berg?

| Yeah, I figured it shouldn't be to hard to get it down there, being aware of what is going in the truck goes along way I set it up really close to how my berg is, and it just feels a little off. I think I might skip supers and 1.9s tomorrow and put some more time through it and see what I can do. I can say I beat the living piss out of the truck today flailing around and not a single POP, crack or moan was heard. As of right now, the berg isn't going anywhere for awhile |

How much does the XR10 weigh compared to the Berg??? If the Berg weighs more than the Xr10, that could be why it doesn't feel right to you. Last edited by stelerzman; 11-13-2011 at 09:47 AM. |

I think it looks great. It's hard to drive a new rig in a big event. A guy will have his mind set on worring about how the rig is going to work instead on driving a rig he knows how it works. You'll kick butt next time. |

Why did you decide to run the battery on the axle instead of on the chassis? | |

I am still interested in your explanation of why knuckle weights don't jive with kingpin inclination.

Let's see if I can explain this, if you take a truck with inclined king pins and measure the amount the axle drops when viewed horizontally while the wheels are at full lock, you will see it is between 1 and 3 degrees depending on how far out the center of the wheel is from the pivot point (amount of scrub). If you do the same experiment with a truck that does not utilize an inclined kingpin setup the angle will be between 8 and 11 degrees, once again depending on the distance between the center of the wheel and pivot point. Now, this might not seem like a big difference, but one can see the effects in certain situations. When you are turning a non inclined kingpin will want to transfer weight to the outside front tire effectively making the amount of weight on that tire larger. This makes it so you do not need the rotational inertia of the weighted wheel to pull the truck around. One will see the largest impact on vertical ledges where one is either trying to turn off the ledge or stand the truck up on one tire. With an inclined kingpin the truck will not transfer as much weight to the outside tire. This tends to make the truck wash out and slide around more while turning and digging. By adding weight to the wheels, one is able to take advantage of the increase in rotating mass to manipulate the truck into staying on a line and not wanting to slide There are a few more inherent traits to the inclined kingpins that cause the effect I am talking about. Namely castor loss and camber gain, but I don't really feel those make as big of a difference I hope this made sense... | |

I noticed on my AX sportsman how the axle tilted alot when at full lock (25-30* caster) yet my XR tuber did not lean over much at all even with really high caster angles. How very interesting... I wondered why all the top dogs are running DH's and no knuckle weights. Last edited by TSK; 11-16-2011 at 02:55 PM. | |
