Very cool C-Model. I should build two of them) Also, nice to see that solution inside) -
Nice one. I like second chassis variation with overlapping wheels. And agreed with matthewclso.
-
I like to watch that evolution of steppers) Always surprising.
-
Incredible creation. How cabin is detaching from cable when it reaches station?
-
Until you start sorting it)
-
Cool, i like design and how small it is. I think i will replicate this chassies for educational puprose. One question - hardcoupling L-motors with one DBG gear in the middle is neccessary?
-
Guys, seriously i just can't stop... Rotation is uneven, but it's smaller than flex axles and can handle torque. Also, this solution is more pricese than flex axles - 360 degree at input will be 360 at output.
-
I think it's my favorite now. Fantastic tubing.
-
Flex axle solution. Less parts, less compact, can transfer rotation only in one direction, but can handle surprisingly more torque. Important to connect flex axles with one end coaxial, another end - with offset. Not one axle coaxial, another axle with offset.

Wow, so complex gearboxing actuation thing... mindblowing. -
I found that shaft with CV joints works good with parralel arms of same length. Or, at least, ideal 90 degree oriented arms, like rear suspension of my Porsche 550. With various weird angles and different arms length - shaft act weird. Maybe the problem is the precision needed for adjusting multilink suspension, that not achievable easy with LEGO parts/
-
I builded front multilink suspension one time. It's not driven, but there's enough space for fitting shaft with CV-joints. Main problem here - shaft will act like another suspension link, limiting hub movement somehow. I feel some kind of challenging puzzle in this topic)
-
Just follow instructions, it's easy to build. Double check switches on remotes and recievers.
-
I used 1/2 pins when i need to connect two regular liftarms and need to secure flex axle inside.
-
I think i need to rebuild porshce box 1 using old clutch parts, just for test and entertainment)
-
There's no u-joints in 42036 inventory.
-
With given parts that is possible. Not for high-torque applications, not so compact, but it's working. I think some better solution is possible too.
-
New red clutch gear have one advantage over old ones - they can be used with pins. More observations - old 2L driving ring have sharp triangle teeth, while new 3L - rectangular teeth with smooth end. Same with new and old gears. And old driving ring can be moved freely for about 1mm, while new driving ring can be moved further (about 2mm), but not freely. Fixing clip act as spring forcing returning to center of ridge. Also - endings of driving rings, where driving ring contact with inner surface of clutch gear - they are different too.
-
Like rear axles at trucks. Two wheels instead of one.
-
I've done some tests with simple 6-speed gearbox. Tested it with hands at each gear in both directions. All 3 variants generate a lot of resistance when lower (higher) gear selected. Both variants with new 3L driving ring works smooth enough, but in comparsion with old parts - there's not only resistance caused by gear ratios, but also some uneven friction. At least i feel like that. And feels like 3rd variant works without any friction at all, after trying 1st and 2nd. And i didn't notice significant difference between 1st and 2nd variants. Also - 3rd variant works ok just being assembled anyhow. 1st and 2nd variant can completely stall if gears pushed too close to each other.
-
Meditative model. Great idea, almost simple)
-
I may join... Is gearboxes allowed? Is double wheels are allowed?

Great truck, i like details of the engine. -
Wow, great observations. More than one mind is better for solving complex problems) So, better to avoid using new clutch parts whenever it's possible. At least when getting from LEGO as much as possible is needed.

Very cool model, instantly recognizble. I like how clean all this looks, especially wheel arches. And i like steering setup - looks like real)
