No! With a motor you can not feel the friction. The motor has enough power to rotate the wheels. But you can feel the massive friction if you turn the gears by hand!

It seems this is a design bug by LEGO. Maybe LEGO should have asked a mechanical engineer before designing new gears. The design of tooth profiles was compulsory in our basic studies: https://en.wikipedia.org/wiki/Involute_gear The old gray gears from my Technic Sets from 1990 have involute gears. Very smooth and almost frictionless...

In the Crocodile 10277 is a gear combination like the screenshot below. A black "12 Tooth Double Bevel" (32270) and a tan "20 Tooth Double Bevel" (32269) between two technic bricks separated by two plates. My problem: it seems that gear combination don't work smooth. It it keeps stalling, it rattles and it runs very stiffly (high friction). I have tried the same gears from other sets, but the problem remains (sometimes worse, sometimes less bad). What is going on? Are these gears ar not made to use it in this combination? Or is the design of the teeths wrong for this wheels? https://en.wikipedia.org/wiki/Gear#Nomenclature

Yes, monitoring is a good reason for a display. To use it as input interface is also a good reason. Thanks. But animations and games are no normal use cases. What about a small (touch) LCD screen with a technic frame around it as an extra and optional component?

Yes, that is exactly the question I had (not answered yet): why is a display on the hub important for you?

I have no idea, but why is a display on the hub important for you? I think the Spike Hub quite intuitive. 2 seconds boot time, choose your program with left/right buttons and press START! The time to the program start should be shortest with this hub compared to EV3 and NXT. Yes, the NXT also booted fast, but you had to navigate through a multilayer menu to launch a program...

Which motors/sensors are included? On the images I can see a distance sensor and a color sensor and 4 medium angular motors (one motor at each leg of the "thing" in the front).... I see no touch sensors and no large angular motors....

A maker and seller of LEGO copies is angry about an other maker and seller of LEGO copies? What an irony...

That is no argument. They sell these components with a Set and why I should not build my own creations based on these Set? Thanks for the hint with Brick automation. I have never heard of that. I think the reason is I never click on Facebook links during a Google search (I have no Facebook Account) . And it seems the project is presented on Facebook only. Works that with Wine (I use Mac OS and Linux only)? Thanks.

Hm... very strange. At the moment I see no option to run a Technic-Motor on the Technic-Hub!! I purchased the Hub and two motors (XL,L) on Bricklink. The Control+App is useless, there is no "Standalone"-Mode to run or configure the motors for an own model or MOC. The App is only useful If you have the Liebherr and all Motors are connected to the provided slots...

It is possible to pair the Train Remote Controler with the Control+ Hub?

Works this with the new Technic Control+ Hub too?
