Those honestly might not cost much more than the crazy expensive original rims these days!

I actually did get it to work in one of my older MOCs, but it was an awful lot of trouble, so I never returned to the design, preferring to use wedge belt wheels as brake discs, and foregoing hubs. (See around the 5:06 mark in this video: https://www.youtube.com/watch?v=eql3xzet69U&t=43s) I agree that the new rims should make this much more practical!

I'm trying to wrap my head around how the rotor head is working. It looks like that five-sided part is mounted on a vertical, rotating beam, and there seems to be a bush mounted on that beam to keep the five-sided part from sagging down. It could be that the five-sided part can slide up and down on the beam while being driven, but I can't figure out how it would be controlled, so I'm guessing there must be another bush or something above the five-sider to keep it locked to the beam's height. The beam then would likely be driven from below, but be free to move up and down from there. Perhaps it goes through the center of a turntable, being driven by some square build on the top half of the turntable, and raised and lowered from below, through the center of the turntable. If this whole assembly is lifted, and all those links coming from the rotor blades are attached to something of fixed height at the bottom, we would have a collective pitch control. Of course, leaks did mention having cyclical control as well, and there's no reason it couldn't have it--if those links were attached to some kind of tilting swashplate in the helicopter body, we would end up with both cyclical and collective. I can't say I expect this, though... It'll be interesting to see how close this guessed mechanism is to reality!

Here's another drivetrain model for my series, this time a relatively simple one. It's a model of the drivetrain of the seventh-generation Chevrolet Corvette ZR1, and has a few different features. It's got a manually operated friction clutch, a realistic joystick-operated 7+R manual transmission, a friction-based adjustable rear differential lock, and a simple adaptation of the Corvette transverse leaf spring suspension. Features: V8 piston engine, driven by a PF L-motor Worm gear operated friction clutch Joystick operated 7+R manual transmission Friction-based adjustable rear differential lock controlled by worm gear Transverse "leaf spring" double wishbone independent suspension. You may notice that this gearbox is really long, but that's really just a limitation of the Lego parts. For comparison, I think this might be a good opportunity to show off some of my 3D-printed gearbox parts. Using them, I could have made the gearbox only this long! Overall, I was fairly happy with the model, but there wasn't anything super interesting about it, in my opinion. https://bricksafe.com/pages/2GodBDGlory/corvette-zr1-drivetrain-model

I don't think the hose itself is an issue, because it can theoretically be fit into the box; but I think if the plastic nozzle on the top of that cylinder is protruding, it is probably not ok, because it cannot be manipulated to fit.

I watched this earlier today! It's an amazing piece of work, beautifully overcomplicated and precise, with a great steampunk feel to it. I want one on my wall now!

Ah, but you forget to count the left and right variants of the triangle panel separately, so it would be a total of nine, beating out the BMW!

Does anyone know if/how the new 14T gears can be meshed with each other? It looks like they should be able to, but likely at an unusual spacing, probably a half stud off in two axes.

Wow! I was afraid replacing the System would destroy this model, but it still looks great!

I love your geartrain for the outriggers! You're using two unusual gears in there with the 14T (A personal favorite part of mine) and the 20T idler to make a very clever, compact mechanism.

Amazing MOC! Those outriggers look much more substantial.

I think I did something similar when I built the set, and then, just for kicks, I slapped a couple buggy motors on the sides and made a bizarre hybrid. It was a nightmare running both pu and pf simultaneously, but it was never supposed to be a good idea!

I did it the same way @johnnymmentioned, with the 20t single bevel idler gear inside it. The profile fits nicely!

I've done a design like that before in very high-powered models, with an extra 12T gear at the back as an idler, making a full square of gears to distribute the forces.

I'm happy to see some progress! That's an unusual differential lock you've got there! I've never seen those Bohrok eyes used to shift driving rings before, and it's not common to see both sides of the differential have their own driving ring. Really you'd just need one side to have the driving ring, and just lock its axle to a fixed gear on the other side, but your design does look a bit more efficient when unlocked, because the locking shaft would be undriven.

And 2008 didn't really have anything in the price range of 2005-2007 or 2009-present

Very impressive! I love the fact that you used the Control+ electronics for it rather than the Mindstorms ones; C+ seems to have most of the programmability of Mindstorms, but its inclusion in so many sets that don't need its programmability make it cheap!

Calipers that would slot into the hubs? That'd be interesting to see!

Yeah, this thing is sweet! Massive functionality, and good looks. I do think it looked a bit more refined before you added the rotating cab, with the pneumatic outriggers, but I think this unique function is worth it. If possible, I'd like to see the outriggers appearance change a bit, though. The arm itself on them looks a little too simple, so if you could add a foot or something, I think it would look better.

For 99% of models you'll be right, but having a larger gap between rim and disc will allow for more options to make the brakes functional, which could be neat to see in MOCs. I tried once with Porsche rims in a model, but it was very challenging and didn't work great. This could at least be a side advantage of the disadvantage!

It's possible, but I think it's more likely that those black spots are just decoration on the rim itself, representing the five lug nuts on the real car.

At this point, I wouldn't expect it to end up as a limited edition. It seems like bad business sense for Lego, and would just be a break from tradition. Sometimes we hear a lot of strange things in early leaks, and I wonder if this might be one of them. It sounds like the real car is a limited edition of 599, could confusion have come from that? Who knows, though!

Looks like the roof might be made of the same part in black. Also these in lbg!
