Why not use a motorcycle helmet? They're 100% safer than bicycle helmets.

Hmm.. Also i need to add that i couldn't do any visible damage to the old CV joints simply by spinning them at max angle by hand.. Heck, i even had them over the maximum angle and spun by an XL motor and they just skipped sideways without getting permanent visible damage.. There we have brand new CV joints that are getting destroyed simply by being spun by hand..

Well in some countries there aren't any ad's that are misleading. Warning banner or not. Guess it's an american thing?

Okay i have not seen that ad.. They made it look completely indestructible.

When a gear is turning, the second gear it's turning will turn in an opposite direction. So look at the gears and think: "Left, right, left, right, left, right.."

I think lego should design a good strong part even if it's more expensive. After all, they're known for their high quality.

TLG's whole motto was that their stuff is only the best quality. Haven't they tested these CV joints at all? Disappointing.. They should have made bigger U joints as they have proven to be superior in every way.

They're only 7 euros a pop there.. Go search in brickowl and people are asking for 21 euros a pop. Insane

Well a swinging rear axle could work. But i was thinking more of that the rear axle + xl motor would be hanging from springs and those ball cup arms so it would also have up and down play and sideways swing.

Interesting study. I'm surprised it even popped. Well done!

Does anybody have any tips on an 13 stud wide rear axle? This is what i came up with: Very heavy duty and motor on axle. Always locked so no diff. The speed and torque can be modified by changing the gearing on the portal hubs. It's a crude design but compact i guess. It's hard to figure out a suspension for this axle though. And how to attach the XL motor so it won't just fall off. Does anybody have any 13 stud wide designs (from tire to tire.) (i guess it's technically 19 studs if you count the tire width.) What i need is an axle + suspension so i know how to attach it. I can also mount the motor to the body too. (i'm using the front axle that @efferman posted.)

Everything works in LDD.. But doesn't work in real life.

That looks like a cool chassis for a mining truck.

Here's another great axle from @efferman. He designed it for my need. -13 studs from tyre to tyre. -Non driven -2.5 studs of ground clearance. -Good steering angle. -Durable

Very interesting system with the servo. Well done! Nicely compact and the bodywork looks great.

Thanks for sharing!

Here you go: https://www.dropbox.com/sh/o6ni1g3l0zxbh2m/AAA_3BVbybzWwz1hnpP0vohKa?dl=0 Enjoy! Also save them for future. The user might delete the old file so if this question pops up again, you'll have them saved.

I think you should read this: https://io3dprint.com/3d-printing-lego/

Well lego is made out of ABS. It would be good to use the same plastic so the characteristics are the same. I'd also be interested in this 3d printing thing.. I think i made a thread like this once or asked about it once. Didn't get much answers.. If you can figure out a nice suspension with lots of travel and great steering lock then PM me with your ideas!

Great work @efferman!

Now only to figure out a more compact version. :)

Has anybody done a version of the 42099 made by old parts like PF stuff and old hubs? I like the front axle design. Looks great for crawling. I wonder if it's possible to do with old parts? Perhaps smaller scale too using the smaller turn table. I'd love to have a more compact front axle using the turn table + spring combo.

That thing will 100% flex outward when weight is put on it.. If not even as is by itself.

Needs to be modded to be RC next

I dunno man.. Most land rover owners haul coffins just in case
