Here is the second part of the review with all the details of the Control+ profile and a quick comparison with the Liebherr - kzbin.info/www/bejne/aGileHh4q6aFlc0

[@R1pp3d]

I feel like there's always a compromise between building experience and playabillity, adding a motor for every function makes the build less interesting imo, but makes the set more functional. I don't really have a strong opinion on this set other than that it's expensive.

[@Ntgaming26]

i think that if it wasnt using those mechanical pistons but pneumatic pistons and 1 motor plus a pump for making air pressure you could have better function but also a more interesting build

[@michaelfoulis7438]

@@Ntgaming26 If they found a way of making it powerful enough to move parts of the model and work through the app it would be much cheaper and better

Another amazing review! Endless apprise for remaining so UNBIASED all these years when it comes to reviewing Technic sets! Even though you get early review models from the Lego group. Also, the amount of work you put into each review to make it so detailed is beyond imaginable. Thank you.

[@Richard1855]

I work for a Caterpillar Dealer in Australia and CAT (that's what the manufacturer is called by dealers) has informed us that they are changing the naming convention of the entire product line. So this bulldozer, or correctly called Track Type Tractor, will now be named D11; distinguishing it from the proceeding model D11T. CAT have dropped the alphabet at the end, going forward. A bit of trivia for you. Thoroughly enjoyed your video and comments on this model. Looking forward to your next video.

[@RacingBrick]

Thanks for the information! Based on this the box design should be changed to the version we see online

[@thecarspot8768]

@@RacingBrick not trying to be rude but this is fake as lego said a few days ago that this happened s not one of their sets and you can tell because it shows on the front of the box that they don’t have an app to remote control any of their remote control vehicles but they have a controller instead and that’s how you you tell this is fake lego technic set

[@francis9131]

I feel like they should have motorized the ripper tilt and made the ladder manual. I do like how they managed to get 6 functions out of 4 motors (saving the cost of 2 motors and an extra hub). Overall, the looks are amazing. The price tag, not so much.

[@chrisbushnell2378]

The ladder is motor driven on the real thing though

[@cthunter41]

The T denotes the model version in the US. I believe T is the latest offering of the D11. Awesome model and great build! Told my wife this is what I want for Christmas

Finally a set to use as the basis for a MOC to recreate the House robots from Robot Wars!!! 😂🤣😂

[@Cricketbadger987]

I was already getting Shunt and behemoth vibes watching this 😂

[@ygrbooks]

Thanks for this video. I have just finished building the RC-Bulldozer by Happy Build® 22011: 7 motors, two hubs, RC (and some kind of "Control+" if you so wish), rechargeable batteries and excellent parts at a price of €180. It is a MOC that went into serial production, so it is not perfect in all aspects of the build, but it works fine. This means that I will not ever be needing the Lego version as it has fewer functions, no RC, no rechargeable batteries, fewer motors (which you are not free to use for whatever you want unless you buy additional stuff), just one hub, a sticker sheet (but no Cat prints - if I understand you correctly) and costs the princely sum of €450. It is just a no-brainer.

[@whatiswrongwithwhatihadwankers]

Is Happy a lego product, if not I don't get your point.

[@bami2]

Great review, went really into the details here.

[@robl39]

In my opinion, this is the #2 Technic set of all time (#1 going to the Bucket Wheel Excavator). This is a must have for any Technic fan.

D11T would correct for CAT's latest model. The black on the blade would a CAT Carry Dozer option. Can't wait to get this.

D11t is another configuration of the d11 with the acert 32 engine. It is the correct nomenclature for this dozer…

[@leochin9649]

thank you master, waited for looooooooong time

[@dennisberg2474]

Very cool, but I agree a $350 price would be far more appropriate than $450

[@willemlu]

Thanks for another great review! Normally I skip the building part of reviews, but your modular build approach with explanations is very interesting, so I watched the whole video. Excellent idea! 👍 Another overpriced Lego Technic set. For this price it should have had extra hub/motors to power additional functions. A shame, but at least it is a true flagship set …

[@fishbrix3809]

true

[@Starling_54]

Dang, that box is huge

[@TheMetalButcher]

Blade shouldn't tilt forward back, but side to side. It should only have an actuator on one side and fixed on the other. I guess that would have added a fair few parts.

[@TheDethsight]

My second favorite technic set I've built! (first being the rough terrain crane). now, if only we got something in this price range THIS year, rather than the insanely overpriced Liebherr crawler crane. half the piece count as this set but has all the hubs and motors lol. i'd rather get the Liebherr excavator or bucket wheel excavator for $700.

[@parazels83]

This is a one of the best Technic sets ever. Much better, than the excavator.

[@M3dicayne]

4:39 Nope. That's just a differential with only 3 gears. You can even add another frictionless gear and it works like a charm. Also, I don't like Lego's price at all at this point for a technically incorrect version where the drivetrain is just on the wrong wheel...

[@leokimvideo]

BUT CAN A MINIFIGURE DRIVE IT

[@JSLEnterprises]

My last technic model in my youth was 8857 (the street chopper from 93, however I still have the set in its alternate dragster form); unlike that one, I find all these new sets have blue, red, orage, and a plethora of other multi-color parts, which is fine if you're semi-blind from age, or if you're attention span is that of a goldfish where you cant focus on any specific area to notice the details when its all the same or similar color. Given that these are 18+ builds, that cost upwards of $500, 1) they should have same-color-parts for where they go in the overall, 2) All pieces that currently get stickers should have actually been printed (like the Ferrari)

[@Wichelroede]

I’m starting to find your reviews better than Sariel’s. No bad word about Sariel’s reviews, however! It’s just the spoken text, I guess.

[@Konacrusher]

He's also much, much more likeable.

[@Polsnulspace]

This is top of my list at the moment but it still needs to drop in price quite a bit before I make my move. I'm hoping for £260-£270 just like the Liebherr Excavator did.

[@Karl_Johansson]

It would be more fun to if lego made more of a thing with these great designs.

[@ianjones7486]

A very cool model and a great representation of the real thing. It's a little large as the Leibherr is considerably bigger but I cannot wait to get mine. I do work in open cut coal mining so these are wonderful items.

[@DennisDinges]

Are there any rumours about the next big lego technic product that comes after this bulldozer? 2022? Maybe a big hauler as seen in the mines around the world?

[@catzzzz1450]

Of course,there are lots of romours on KZbin or other websites about Lego Technic will be releasing the most expensive set ever,its the Liebherr LR 13000 which the biggest crawler crane in real life,the price will be ridiculously 600$ and coming this summer

[@GtPDDV]

I noticed that if your technic set includes tracks, you WILL have 2 spare

[@Osomeguy]

Thanks for another thorough review! Looks like a pretty cool set but definitely overpriced, especially compared to the Liebherr which has 3 more motors and 1 more hub. I know they did it for authenticity but it's a shame the tracks are yellow because that limits MOC applications

[@RacingBrick]

[@xaytana]

The track tensioners are a surprise, probably the last thing I expected from this. Still a disappointment that the blade lift doesn't have a new xxl linear actuator, and instead a half fake actuator. The collision of the blade with the fake portion of the actuator is an absolute joke, reminds me of the Osprey's destruction of gears, or the Zetros' rear diff carrier allowing for gears to unmesh under stress; poor design is really starting to become a consistent theme, isn't it? The ripper is also a disappointment. I'm also still disappointed that Lego decided to throw the 18+ tax on this when the price could've instead covered a second hub and given us blade lift, blade tilt, ripper lift, and ripper tilt as separate, simultaneous functions. The design is alright, I guess, some of the techniques are a bit odd, though. What I'm curious about now is the performance of the new tracks, especially on hard, smooth surfaces. I'm also curious about compatibility with the rubber pieces that Lego uses as a bandaid for their poor track design.

[@paologalbiati3782]

The rubber pieces are useless because they can't touch the ground. Sariel show it in his review.

[@jakesnyder2667]

@@paologalbiati3782 Ah, yes, mention another content creator entirely, where there's a fairly large chance that a person hasn't watched that creator's video or doesn't even know of said creator. Hmm, I wonder why the original comment mentioned the rubber pieces in the first place _on this video_ when they could've just watched Sariel instead. Maybe it would've been better for this content creator to have shown this flaw in the original video that this comment exists on. Also, Sariel only showed the rubber studs, not the much taller rubber bars, and I wouldn't be surprised if the bars are tall enough to surpass the new track flanges. Rub a couple of your brain cells together, this is simple logic, it's not that hard to figure out.

[@adrianprepelita8683]

The model is great! What else can you expect from Markus? The price? Again, 50-$70 more than it should have cost. I would much prefer to put some money away and get this instead of the Zetros.

[@miketechnic5.0]

idem

[@ArtisticPerfection]

Half of the dozer ops I’ve ever worked with have never put their ripper in the ground, so as long as it lifts in the air, then I’d say it’s pretty accurate XD The angled seat, the bogie suspension, the cannon track tensioner and the blade stabiliser bar were all nice touches. I like the big front grill as well. I’m sure the blade tilt will have electronic limiters built into the controls in the final release, the blade on the real thing doesn’t tilt back anywhere near that far. If the base plate of the blade is parallel to the ground, then it’s rolled back too far
