In the set up with one motor and no linear clutch, there is not enough torque so the gears would skip instead.

Again, this is not necessarily true. If the motor does not have enough torque, it could just stall, without skipping the gears. Depends on whether it's easier to skip the gears or stall the motor.

I think the weakest link is the linear clutch you introduced, and the LAs have a stronger clutch (they have to lift heavy weights, so a weak clutch would make them useless).

I'll try the hard coupled motors with no linear clutch to see how they perform then.

They should perform better, the question is how do you know that? If the single motor was struggling with the boom, the two motors should be able to lift it with no (or less) struggle. But if the single motor was not struggling, only slow, then you won't see the difference.

I'll remove the linear clutch and test 1 motor vs 2 hard coupled motors.

You were right. I rebuilt the 42215 gearbox with two hard-coupled motors, this time without the linear clutch to the base LAs.

The two motors showed sufficient torque to lift the arm at playable speed.

Good to hear that there's improvement!

Someone made a 2x2 technic pin, I found it on Reddit. It's pretty cursed lol.

[Auroralampinen]

Sorry, i have no attachment to among us nor i have played that. But that looks like among us;). 

[NV Lego technic]

Cursed as it is, the bar hole is kinda clever. If Lego made that part they wouldn't have thought of that.

[2GodBDGlory]

Dang, that is weird! I do see how it could be useful, though, to allow a structural liftarm and a pivot to inhabit the same space!

[pleegwat]

Looks like a low-friction version could be useful as a higher-load slip bearing.

Quite a few important Technic pieces are being discontinued at the PaB store, so now's the last chance to get them. Full list here:

Ok, why the planetary gear wheel hub is getting discontinued. And most of the liebherr crane parts(weights and spools) also were single use apparently because they are also being discontinued 

[Zerobricks]

I guess that means none of the 2026 sets is using any of the listed parts? I'm also worried about planetary and portal hubs being discountinied, they have been one of the most versatile parts ever released. But we have seen the PU L motor being discountinied and return in the past, so I'm staying hopeful.

Maybee we could be optimistic and hope that planetary hubs will be in Audi hub housing.

Oh wow, they are phasing out a bunch of parts that were only introduced lately. But I hope that's in favor of releasing new parts! I guess they are thinking that Bricklink will take care of storing all the older parts..

I hope so too! I mean the planetary hub is surely the part that makes much of the bigger RC models possible, so why would they get rid of it completely? I really hope a new version will be introduced, and not that they would be toning down RC stuff..

[2GodBDGlory]

Wow! Most of those losses aren't unexpected, but the planetary hub would certainly be a blow. I suppose if Lego isn't releasing real Control+ sets anymore, they might not need them? Hopefully it's just going to be a recolor or a mold change, though.

That being said, planetary hubs were really expensive on there, and I think I've now bought 4 off Bricklink and 8 clones off AliExpress, so there will still be places to get them

Unfortunatelly if they will be discontinued prices would raise since people have speculative nature...

...but lets hope for better...

Frictionless 3 module long pin is now yet again available in light bluish grey, it appears in the Gameboy switch detail.
