What’s weird is that the package I sent yesterday via FedEx from Oregon to Utah went all the way to Tennessee. Now they have to send it back West to Utah. That is some ass backwards logistics. Unless they changed everything at FedEx. That is how the company was set up and has always been. Everything goes to the hub. That is the only way they could guarantee - "When it absolutely, positively has to be there overnight". |

packages arrive in time.

What is the purpose of the off set rear weight? Are you trying to push more weight toward the DFW side of the car? The offset weight is to assist graviyy to push the car through the transition straight as possible |

Looks like my truck was delivered today. Normal shipping time for USPS for me so hopefully all of your cars arrive on time too.

Here is my truck "QuickSilver". Sending un tested. I feel a fast truck should be able to run in the upper 2.94x range at npwdrl. Anybody have any results from testing?   |

My truck went in untested on a track also. I am not sure what the speed will be. Basically a BASX car with slightly less aerodynamics, less weight in the rear, ungrooved axles, and rolling on lighter wheels. I am thinking it will be difficult to break 2.95. My guess is that trucks will be in the 2.95 to 2.97 range.

If all went right my truck could run 2.949'ish. It was hitting 2.963 when it left here, and Joel's track is right at .014 faster than mine. On the other hand, it could just as easy run a 2.96+.  |

Or, it could take 2.96 trips across the US and back and not even make it to the race. Hopefully, the later two are not the case. |

Not too shabby Ember! Is your MA car fast too?
PS. They both look awesome!

I really don't think they will be there for Friday nights race, I suspect they won't arrive until Saturday afternoon. |

Not too shabby Ember! Is your MA car fast too? PS. They both look awesome! Scott Thanks Scott. No, my MA car is relatively slow, it should run about what it did last month at around 2.929. This month I tried short 1.10" wheels, and could not find any more speed than the tall 1.175" wheels I ran last month. Both sets weighing around 1.24g
Funny thing with the truck. We've recently been talking about different wheel heights on the forum, and since I was previously convinced that taller wheels were faster than shorter wheels, I ordered two sets of truck spec wheels. One at 1.120", the other at 1.185" , both weighing 1.5g .I first tried the short wheels, and while the truck ran consistent and tuned easy, it was slower than I expected, running around 2.985. Not expecting much difference, I swapped them out with the tall wheels, and instantly went down to running around 2.963.
What height wheels are you running on your truck?

Well shit on your MA...
Interesting info on your Tall vs Short truck wheels. When you swapped did you also clean and re-jig the axles? Were both sets of wheels cut by the same person?
My truck wheels are 1.120" tall. Man I hope they aren't turds..
That sucks about your cars maybe not making it for friday. I thought eagle was just being a wise guy with his post when I initially reacted with a lol

If my cars don't make it in time it's my own fault for procrastinating so long. The first thing I thought was I must have done something different with the Jig, but I'm almost certain I did things the way I always do each time. I was seriously short on time and decided not to mess with it and retest the short wheels , so I just left the tall wheels on and got it ready for shipping. I'm definitely going to give them a good comparison test when I get the truck back. The short wheels are from Joel, the tall wheels from Glenn. They are both really nice wheels, identical in every way except height. I can honestly say, with all else being equal, I have never had a short wheel run faster than a tall wheel. MV, Revell, BSA, 100% of the time the taller wheels have been faster for me. I know that goes against conventional wisdom, so whatever I'm doing wrong I'm doing consistently wrong.  |

I will be interested in the further testing.
I can't say for sure shorter is always faster either. Mainly because I don't have enough data or the data I have is corrupt because of other mistakes. I have had "fast" (a relative term to my cars) with short and tall. What I can say though is that currently my best 3 cars have wheels that are as short as possible. But maybe that isn't because of the wheel height?? I cut them that way because in theory the reduced inertia "should" be better.
My gut tells me a taller wheel is more forgiving to errors made elsewhere in the build.
