|  1/18 scale, why doesn't my MRC weigh over 100lbs? What, a full size rig weights in at over 3000 lbs huh? just a guess, so what's up with the scale on weight? It certainly climbs better with another 1/2 lb added to it but I'm not sure where I'd fit another 100. |

1/18 the length, 1/18 the width, 1/18 the thickness. so 1/5832 the mass. Plus, the designs are completely different and with different aims, so the weight will never match. | |

| Yup...different math. The "scale" that you see on RC's only apply to it's size. Not to mention...there's the whole factor of the materials used to build the 1:18 are lighter than all the steel parts of a full size. |

So if I have a cube of steel, and another cube of steel that is 1/18th the size. The smaller one will weigh 1/5832 as much  ? I question the math.It's more like: If you made a full size crawler out of hollow plastic, and a few aluminum pieces, the scale weights might be closer. If you look at CCFBERG's scale tuber build, it ended up being really heavy. | |

| yeah your wayy off with weight because of the materials and a cube of steel and the 1/18 version of it would weigh an 1/18th of the size because its the same material |

It is not because of the material alone. If you had a 1/18th SCALE version of a block of steel it would be 1/18 the lenght so it would take a row of 18 to make it as long. Then you would need 18 to make it as wide. Then you would need 18 stacks of those high! Therefore....18 long x 18 wide=324 then 324*18 tall = 5832 blocks of steel If you had a block of steel that was 1/18th weight it would not be the same size. Get it? | |

| Way too much math getting thrown around for something that I am pretty sure was meant to be funny by the OP.  |

| easier math: 1x1x1" cube of aluminum = 1" cubed volume 10x10x10" cube = 1000" cubed volume that weighs 1000x as much. The rig is shrunk in three dimensions. |

| Now I understand how that makes sense. Thanks for clearing that up. |
