New connector in the 21356 River steamboat set, one end has friction and the other doesn't:

So I take it this is like a 4L axle connector, with one stud on the one end having friction for the axle. What I want to know now is how deep the other side is. Does it have a full three studs of sliding space? If so, that'd be a great part for extendable driveshafts  in the future!

That sliding axle connetor will be very useful for truck which need to sliding axle for suspension but to tight for fit large CV joint and to small range of small CV joint.

Huh, interesting! Similar to the engine one in the 'Vette, but missing the one connection

(for instance, some sort of custom car set where you can swap out different types of engines)

In the old days, this would simply be achieved by meshing gears. For example, in set 8448, one can insert the piston engine in the front or in the back. The engine assembly has a gear that meshes with a gear in the chassis.

Oh, for sure, and it's not like that option has gone away. But this provides a nice alternative if you want a modular build of any sort with a continuous axle running between removable sections.

[Carsten Svendsen]

That axle has been a wish of mine for DECADES! It's everything you need to make a proper working PTO on tractors and other equipment. Now we don't have to line up all kinds of weird geometry, and can actually make it like it's meant to be

[SNIPE]

Loving these 2 new parts, the 5L axle joiner will also be able to be used to connect up 1.5L  of excess axle where as a 2L axle joiner could only go on the end because of its center stop. Yes you could use a small CV joint but that had a male axle on one end, and the female half has a 1.5L axle hole without friction, and it hinged.

Like this, as a single example:

This has only 0.5L of the axle inserted  weather you use the top axle joiner configuration or the bottom axle joiner configuration.

I would imagine it would be the full 3 studs deep - I can't see any reason why not.

Curious that the most interesting new technic parts seem to be coming from non-technic sets these days...

This new piece will indeed be great for telescopic drive shafts on trucks. There is the sliding CV joint but the prop shafts on trucks usually use universal joints, so this will be more realistic. Plus there's all the other already mentioned uses like PTOs and modular builds and such. 

[aeh5040]

Looks like we also get a 3-way connector in red in the steamboat, which somehow excites me more than it logically should...

Every possible wheel color with new Tr.Bright green tire

[2GodBDGlory]

Impressively obsessive!

If this comes out in black I can see it being perfect for rollcages and rear wing supports 

[TechnicRCRacer]

Someone found an interesting prototype part I thought was worth mentioning here. Apparently it has an official part number molded inside. It is a rubber track with hard plastic connectors molded in. I have no idea how recent it is and I bet it probably won't be released.

[2GodBDGlory]

Huh, that is very interesting, with the potential for the grip of rubber tracks and the adjustable length of plastic ones!

[johnpolket]

Very cool that I found this. I actually own the two in the picture. There's two others in the wild somewhere, but I got mine on a fb auction. They are from 2013 btw

[msk6003]

Looks like prototype of this

(Even this part came in 2006)

[Takanuinuva]

Prob not the topic to ask this. But it is part related.
Any idea why this part has a spare included in sets? It's not a 1x1 part

It is included due to its low weight.

Fair just feels odd since the 1x2 tiles aren't also spares. I guess that much plastic variation makes that much of a difference.

[Ngoc Nguyen]

Can the 8z gear spin reliably without touching the 12z gear in this setup?

[Zerobricks]

Seems like the 12 tooth is also grinding on the upper beam.

What upper beam? There's no upper beam.

Edited April 9 by Ngoc Nguyen

[Zerobricks]

From the perspective, befoe the 12 tooth bevel gear seemed to be touching the above flip flop beam. Also, yes, the 8 tooth does rub against the bevel gear, it's very easy to build and test yourself.

Also coming in Tan. It might take a while before we get this technic connector in a non-botanical color...
