Just now, Jeroen Ottens said:

For 5 holes you'd need more than 2 knobwheels in the same plane. In my experience that doesn't work. The friction @Erik Leppen mentions completely blocks the drivetrain from time to time.
I never properly tested the slack, but I always had the feeling that knobgears have less slack than normal gears (that's maybe also why they have more friction )

I know that I need more than 2 knob wheels; but I was thinking at first place as comparison...my problem is that I have very very limited space and only one train battery box...so I think to place servo somewhere else and put battery box over L-motors...I have a feeling that I'm running in circles...

@I_Igor Regardless of the gear type selection, you will need 3 gears to have the servo output aligned with the steering shaft.  This will create slack, no matter the option. In my experience the only way to avoid this is to have direct steering.

I agree the only way is to integrate it somehow on axle...but it is tall ...

Thank you

I believe it’s used to hang the mosaic sets to the wall.

Indeed but we all know that we will use it as a trailer hitch :)

Also those 1x4L tiles can be used on tank tracks, as see in the LEGO nintendo NES + TV set.

Thank you for fast response; the truth us that I look for solution how to transfer power from PF servo but steering shaft can only be placed 5 holes below servo...and servo is to big to be placed on axle (axle something like on 9398 set without portal hubs)...

What about a 16T gear on the servo, 16T on the steering shaft and put a chain around them.

Actually I made solution with universal joints, but since rear part of real thing is slightly raised I plan to install rear axle one stud lower which should give me enough space...but due to all complications and tough and painful things hoped up I can only hope to find hour or two without distractions to test this idea. Problem with chain is that it actually rubs on beams because it does not fit within one stud width (OK I have old chains from 1970s so perhaps with new it could work...)

Thanks for help Mr Jos (the Boss)

Looks like it is something perfect for the trailer truck, the thing "Fifth Wheel Coupling".
 
Things like this, not sure is it the right name.

Most of the parts of the 42113 Osprey are now available on Bricks & Pieces. Sadly, the rotor blades aren't available yet.

Nonetheless if you search for part 65422, the black rotor blade does does up in the catalog, so there's hope it'll be possible to buy in the near future.

[SNIPE]

Wew I just realized something when building the 42114, you can fit the white linear clutch inside of the black half of a mini turntable

Now you have a 28 tooth bevel/spur gear with  a built in linear clutch.

The white half meshes with the turntable while the DBG half can rotate independantly if theres too much load, otherwise it rotates with the white half, And the turntable and clutch seperate with no damage.

Note that it only wants to go in a certain direction, the opposite way just pops out. It's almost like they were made for each other.

Ill upload the photos and video when my computers start working

nope, the closest you can do is part 48989 connector block with 4 pins.

Did anyone manage to order and then receive 42113-specific parts from B&P? Now they are not visible on the site. I also received a refund to my card which I used to order them on 16th of August (but no email about my order being cancelled, so maybe they are going to charge me again later)

I have question for owners of part 6539 and 18947 (driving rings). Is 6539 slightly narrower in diameter than 18947? Because I am building live axle with diff lock and 18947 touches diff case ;/

So the pin connector is coming in Lime? I can't find any information in which set(s)... anyone knows?

[TechnicRCRacer]

@keymaker6539 is actually larger in diameter than 18947.

Thank you. I'm recreating this solution:

And somehow 6539 is ok in this build (I assume, I do not have it). But 18947 touches diff case (not much, but still). I know that 6539 is shorter - 2 studs but I do not see how it fits there.

I just got my first couple new 28T differentials. I was quite excited about them, and planned to use one in the rear axle of a truck I am working on. It has a solid rear axle, so width isn't a problem. I had been planning on using the integrated part of the differential with a driving ring for locking, and driving the differential perpendicularly with a 12T gear, but I can't come up with anything that can take high torque without skipping between the 12 and 28T gears. Does anyone have any suggestions?

If not, I may just relocate the differential into the frame and run the half-shafts down to the axle, which would allow for easier differential locking.

Thanks!

Use the 7x11 frames, they are perfect for the new diff and locks. I'm working on just such axle now.
