|  Scale weight?
This has been bugging me, if a 1:1 Defender 90 weighs say 5000#, how much should my 1/10 scale D90 weigh in scale weight? Me and a buddy discussed this once but I'm open for more disscusion, because I have no idea!  |

This is just a guess, but take 5000 and divide it by 10. That should be the actual scale wieght. But 500 pounds seems very heavy!

I'm sure you can look it up on google to find the exact formula (if one exists) for converting though. | |

I think this has been discussed here or somewhere before. Basically, calling from memory, the scale is a 3-dimensional value so weight needs to be square or cube rooted or something.

It's cubed guys. Read the post 88, 98, 99, etc...I have seen this come up a lot on here. Droop Vs. others It's mass not just size you are dealing with. |

I think if you took the weight of the scaler and made it twice as big, it means 8 times more mass???   |

1:1 weight divided by the scale cubed.. 10*10*10=1000 5000/1000=5lbs |

I think most scallers Ive seen are far too light. When they drive over sand or mud they should push into it and make a rut, rather than skip accross it like I see so often. Im not sure scale weight is going to 'look' right though since the dirt may not squash so easily. I have thought a lot about adding weight though.... you could use some drill bit cases (the ones that slide apart) filled with ballast. Then place these boxes over the axles or where ever most usefull. How about adding sand or lead particles inside the tyres? This would eliminate suspension squat, there fore making the most of the ride height. Also you can then configure the weight distribution to counter act any imbalnce caused by having the battery pack or a servo off to one side for example. Just my thoguhts on the subject.

That's only if you're driving over "scale" sand, though. To make "scale" sand, you'd need sand grains that are roughly 10 times smaller than the (~1/16mm-2mm) particle size = (~1/160-1/5mm) Now we're talking silt or very fine sand.

Then your tires better not be 3" wide. Make them 1" wide and you'll start to see these "plowing" issues you want. | |
