Current state: More photos coming later. Does it look like a Chinook to you?

Just so you wait. I'm working on the finishing touch of the model and I'll show you how cramped the interior is.

9 studs. While this B model is only 7 stud wide.

I was about to reply to his comment to say that I will try the normal 2-function independent gearbox first. But then I started building the body and learned that there is no space for a gearbox, sadly.

It turns out that the whole plan for a motorized ramp is a pipe dream. The battery box takes up all the space in the body. There is barely enough space left for the rotor drive axle.

What's the best candidate for the B-model of a dual rotor military transport aircraft? Another dual rotor military transport aircraft, of course! In this case, a CH-47 Chinook. Given my fortunate access to the 42113 and the lack of a satisfactory Technic tandem rotor helicopter (42052 B isn't quite aesthetically appealing), I have decide to build a CH-47 Chinook from the parts of 42113. I will use this thread to record my progress through the design and the build. This is my first MOC ever, so I don't expect myself to finish the build any time soon. My plan for the thing is as follows: Size: The set is supposed to be scaled around the rotor blade, which is 19L long. But since the blades are not upright in the blueprint, I scale the model around the distance between the two rotors. The measurements are very auspicious for the build, as they are approximately odd units of studs. Some quick numbers: - Body length: 42 studs - Front rotor length: 7 studs - Rear rotor length: 13 studs - Body height: 7 studs - Inner body width: 7 studs - Total body width: 9 studs - Piece count: Less than 1000 pieces. 42052 B uses the biggest rotor blade and uses 1002 pieces, it's clear that this model will have less pieces than that. Color scheme: Grey and Orange. There used to be a real-life Chinook with this color scheme, used in the Vietnam War. Functions: Retractable landing gears is a common feature that appears in most mid-scale Technic aircrafts: 9396 A, 42025 A, 42066 A, 42113 A. However, since the real Chinook doesn't have retractable landing gears, that function won't be included. There is no string in the set, so no motorized winch either. That leaves only two functions for motorization: spinning blade and lowering rear ramp. As far as I know the rotors in helicopters only spin in one direction, so I intend to create a 2-switch modal gearbox: Motor -> First switch -> Second switch The first switch will switch between the spinning blades and enabling the second switch. The second switch will be a multi-direction gearbox that controls the rear ramp. That means when the blades are spinning, the second switch is disabled and the ramp isn't moving, while when the ramp is moving, the blades aren't spinning. This design is similar to 42055 B-model's gearbox. As a MOC thread is should demonstrate some level of serious intent toward the build and should not merely express wishful thinking, I will conclude this introductory post with a photo of 2 hours of disassembling the Osprey. As this is my first time designing a MOC, I'm completely clueless of the design process. Now that I've chosen the scale, which part should I start first? I'd love to hear inputs from you. That's it for today. Next update coming soon.

Yes

I did that.

But then, even if this thing has three rear axles and supposedly one front axle, it's still a four-axle midscale truck, like 42112 or 42108. Neither of them has a part count close to 2000 parts. An alternative model of 42108 in the form of an American style tow truck with three rear axles has a piece count of 1171 https://rebrickable.com/mocs/MOC-43434/timtimgo/42108-american-tow-truck-alternate-build/#details

Me after reading the leaked info, to Zetros: How dare you stand where they (42043, 8110) stood?

This thing is explicitly 18+ , like the Ferrari 42125.

https://www.lego.com/en-au/product/the-batman-batmobile-42127 Go nuts.

The real machine has 3 forward and 3 backward gears. I think TLG may implement that.

To sum up

With 2017 pieces, this thing is amost certain to come with a second vehicle. None of the Technic tow trucks so far has that many pieces. Even the biggest one so far, 42070, only gas 1700+ pieces.

So, 1379 pieces, but at the same price at the 2017-piece Tow Truck. I'd say it's this set that has manual pneumatics.

I was about to say so as well.

9397 is on at the same scale, yes.

Just to put thing in context, this thing is even more expensive than the Porsche 42056, which has a retail price of 300 EUR. It's treading in the premium supercar's price tag range. It'd better have something that make deserve that price tag.

I think no one has mentioned that this set has the coveted valve from 42080 as well.

Meanwhile 8275 has 1384 pieces.

2108 pcs and 329.99 EUR means this thing is basically a beefed up and licensed 42099. C+ is most likely confirmed. A Technic hub only has 4 ports. Two are for drive and steer. It doesn't make sense for a crane to only have 2 RC functions. A minimum viable crane at least has 3 functions: slewing arm, raising arm, and moving winch. Unless... This thing uses 8043 gearbox. It can do a gearbox with 4 motors, and one of them controls a mode switch. In the drive mode the other three motors control drive, steer, and front winch. In the crane mode the other three motors control slewing arm, raising arm, lowering crane winch.

@T Lego Any chance you may update the design with new panels from the 42125 Ferrari?

According to a photo from Grohl's FB page, these two sets are designed by Kasper Hansen. A quick Google search reveals that he joined TLG as a Lego Technic designer in 2019. https://www.linkedin.com/in/kasper-rene-hansen/

Unpossible!
