|  Just trying to figure a weight thing out
The idea is to have as much unsprung weight as possible on your rig. Then I see knuckle weights to help get even more weight off of the wheels for more wheel speed and less stress on the gears. And I noticed guys generally add 4-10 oz per wheel depening on the rig and setup. So why is it that everyone wants a light weight axle only to run extra weight on the wheels, or adding weight to the knuckle? Wouldnt a cast heavy axle take care of all that? You could run a heavier axle (which is what knuckle weights do) with minimal weight on the wheel to ease drivetrain stress. Please let me know if Im missing something.

You notice where those knuckle weights are placed, correct? At the ends of the axle and down low. Weight in the centerline of the axle and up high is not as helpful....  |

Plus weight in four corners is better than weight in the middle for balance.

so a light case and heavy tubes would be the ticket. And the tight rope guy looks like a cast axle to me, heavy in the middle and weight on each side to balance. You dont see 5lb dumbells on the end of his beam.

Inspected my worms in my losi the other day and they are still good but Im getting some beefy motors and I dont want to have to replace em . I saw a cheap set of bullies in the classifieds today thought about putting the MOSI up on the chopping block. But Im not sure yet.

Well, I used to run heavy tubes, light gearcase in the front and light gearcase and delrin tubes in the rear on my bully. It was quite stable and had good front to rear balance without any extra wheel weight...

Another benefit to lightweight plastic axles is friction. Dragging a heavy aluminum axle across the rocks doesn't work real well after a while. Steel or titanium would be a different matter, but you don't see many of those and they're usually cost prohibitive for most people. Plus, when everything is light weight, you can add weight where you want it to be. |
