2H2010 Technic sets - First comments

Now that the images for the 2H LEGO Technic sets are available a bit everywhere, lets take a closer look on them.

First we get 4 models in a row for the 2H, what hasn't been usual. And lets see if you wont get another late model, like we did last year for the 2H and we also we will on the 1H2010 (8041).

We got first info about three models to come (8051, 8052 and 8053) an later started the rumors about a 4th set, which turned into a magnificent remote controlled 8043 Excavator.
Still don't know what really happened with this poll... , but whatever it was, may have not been a coincidence.

Now taken the previous descriptions and the new images, lets dig into the new models.
So far no new functional parts have been identified in these. Perhaps only a new design for the rims in the bike below.

8051: Motorcycle

This looks a very realistic Race Bike, in the same style of the previous 8420 Street Bike, released in 2005.
It features the same fantastic tires as its predecessor but the rims themselves look to have a new design. Hopefully symmetrical this time.
As before it also get a transmission chain and rear suspension. However I have doubts the the rear shock absorber can be again this magnificent fat 11.5L version, but instead one 6.5L Hard Spring.
Additionally for this new bike version we also get a suspension for the front and steered wheel. Much like in the 8291 Dirt Bike, using 9.5L black abosrbers.
Unlike the 8420 which got a V4 engine, this new bike got 3 cylinders. Most likely a transversal inline V3.
It looks to have two dummy headlights and two panel displays, made of 2x2 round tiles in white.
The bike is predominately red. It has also some of the new small fairing panels (#1 and #2 versions) in black, however mostly covered by red stickers. May you want to not apply them, and get a slightly different version.

The B-model will be a chopper.
The partcount for this model is not yet available, but I estimate it could be in the range of 400-500 parts.

8052: Container Truck

When first red about this I imagined a truck transporting a real container. Well I guessed wrong, but this is still a very cool model.
My belief is that for the size, this a set with a very good playability, while with its "container" loading mechanism it is an original and first ever design into the Technic product line.
It is a model mainly colored blue for the truck cabin and parts of the "container", which is a good chance to get the first blue versions since the new panels line was introduced the last year. As usual the chassis is a combination of black and gray elements but we also get the 11x3 curved panels in a new color (one of the gray shades - Light Bluish Gray, I guess). The final touch is achieved with the application of a few stickers, if you like.
This is a Power Functions set of the box, which includes one conventional PF battery box and one M-Motor, thus in the line of several motorized trucks from the last two years, like 8292 (Cherry Picker) and 8264 (Hauler).
The model offers a reasonable set of functions for the size, which includes the front axle steering through HoG function and a skip with tipping and load/unload functions. Much like the Hook Lift Truck guessed at EB when discussions about this model started, or the Skip Truck by the mythic Jennifer Clark (1, 2).
The skip movement handling is assured by the usage of one Linear Actuator, and the two functions (tipping, load/unload) would require the action of some driving ring mechanism, whose lever is hardly seen at the current image.
For the moment I don't see any evidence supporting the usage of multiple Linear Actuators, unlike suggested by the previous description found.

Can be built into a Dump truck, as B-model.
My best guess for this model partcount, would be around 600-700 parts.

8053: Mobile Crane

At first glance it looks a re-edition from the great 8421 Mobile Crane, from 2005. However it is noticeable the downsize remake from this mythical model and as far as we can see from the box image it doesn't include any PF elements, thus lacking motorized functions out of the box.
Rests to know if it includes any instructions for motorization with the official PF Motor Kit (8293), otherwise I'm sure someone else will do it.
The obvious conclusion is that all the functions are manually operated, like raising and extending the crane, or opening the stabilizers. Probably through a rear wheel like in many other Technic models.

Compared to its larger brother, it includes the same type of chassis with 8 wheels (all steered), but of smaller size, balloon type and black rims this time.
The crane is now raised with a single linear actuator, but we must realize that each LA has a longer reach than one pneumatic cylinder. Thus avoiding the usage of a back-to-back setup similar to the one used with the 8421 pneumatic cylinders. Because this model is smaller, this configuration should also work seamlessly.
The telescopic arm seams to have just two sections, while 8421 had three. However if the description found is correct, this still extends up to 60 centimeters while the 8421 arm extended for 64cm, according to the official description from LEGO. The hook is now made of discrete parts, unlike the steel one used on the previous mobile crane.
The 8421 used the battery box as counter-weight, which makes me wonder what is used in this model to sustain the long arm when extended. Maybe a couple 73090b Boat Weights!?
The four stabilizers open in a star like configuration, which is a debut in terms of official LEGO Technic sets. This system is operated from a gear (wheel) at the backside of the model. The outriggers themselves are also independently and manually operated and each one has its own mechanism with a worm gear used to firmly push the base against the ground. The worm characteristics guarantee that outriggers won't pullback themselves by action of the model weight.
The color used is the typical for this type of machinery (yellow again), however it would have been a good opportunity to make something different, if using of a different color schema. There are also some stickers to be applied in the model, for a more realistic finish.

The visible functions at this moment, are:
  • Raising crane arm
  • Extendable crane arm
  • Lower/raising hook
  • Rotating crane
  • Opening stabilizers, in star like configuration
  • 4 individual adjustable outriggers
  • 4 axle chassis with all steering wheels
Still to become clear, if the model uses any driving ring / gearbox mechanism, to switch among crane functions.

With the B-model instructions, you will be able to build an Harbor Crane.
Again, my best guess goes for about 1200-1400 parts being used in this model.

8043: Excavator

The fourth Technic set for the 2H2010, turned to be a very promising and fully remote controlled Excavator.
A long waited dream, in my personal wishlist.

My first comment goes to the fact that after the release of 8258 (Crane Truck) in 2009, this constitutes an unquestionable break with a presumable evidence claimed by many of us, where TLG seems to have been releasing a major Technic flagship every two years. Probably nothing more than a coincidence, but it has been more or less consistent since at least the year 2001. Such pattern becomes more irregular and less evident as we visit the antecedent years.

This set is a major enlargement to the previous Excavator (8294) from 2008, which was also a tremendous success among fans. It was even MODed to become fully motorized, by many of us.

As we can see from the image above this is a model from a common type of Hydraulic Excavator, with: a tracked undercarriage, cab, main body with engine/hydraulic pump and counterweight, boom, digging arm (dipper) and bucket.
The arm elements (boom, dipper and bucket) are controlled with 4 LEGO Linear Actuators, being two of them used to set the boom position where higher torque forces are applied - They must work in a synchronous setup, by some mechanical artifact (Section 5.3 from TBs Linear Actuators review - Part II).
The used main color for this model is yellow again and we can see several from the new fairing panels being used. Another good opportunity lost, to re-introduce the orange color into the Technic theme, despite I admit that may never happen for a couple of very good reasons...

From the diagrams in the box, it is easily visible this Excavator will feature all possible degrees of freedom in such type of model:
  • Forward/backward drive with turn
  • Cab rotation
  • Articulated Boom
  • Articulated Dipper
  • Articulated Bucket
This new large Excavator has independent articulations for the bucket and dipper, which is also a difference to its recent small brother (8294), where they were tied to work together.

From a simplistic POV this model mechanisms would require 6 motors, to be independent and simultaneously operated. However from the PF orange band in the box we see it differently.
If I’m seeing it right, the list of PF elements this model will include are:
  • 1x PF Battery box (8881)
  • 2x PF IR Receivers (8884) – 4 channels
  • 4x PF M-Motors (8883)
  • 2x PF IR Remotes (8885)
Apparently 2 remotes and 2 receivers, mean 4 channels for control, which together with 4 included motors would allow just 4 simultaneous functions. Unless there is some movement combinations/constraints or a function switching gearbox, these would be the number of functions possible to motorize.
This is however not consistent with what can be expected from such large model, neither with the function diagrams exhibited in the box image, that illustrate all the model possible types of movements…

So we should expect some level of sophistication used by the Designers, to address and solve this challenge or apparent problem.
I’ve just considered two sets of scenarios as being worthy to comment. One with combined functions, thus reducing the number of independent degrees of freedom and another where a set of driving rings are used to switch across the functions controlled by the two remotes.

In the first scenario we would have two motors for the drivetrain, a third motor for superstructure rotation and the fourth could drive the boom, dipper and bucket, all together. While possible, this looks very unlikely in such a flagship model.

The second set of scenarios could consist of a manual lever (again very unlikely) to switch functions from 2 motors (2 in 4), while IR remotes control the set of 4 functions engaged in each moment (2+2x2, e.g. cab, boom, dipper and bucket, or 2 for the drivetrain, cab and bucket).
Alternatively yet another and more sophisticated schema could be used, like the one also proposed by Jovel in the comments to this post (while I’ve been writing the sections for each model). One motor would be used to control 3 driving rings (linked and switching simultaneously), while the 3 remaining motors would be used to control the remaining sections (1+2x3):
  • 2 in de drivetrain and 1 for the turntable moving the superstructure (3 in total),
    OR (after using the first motor to switch functions)
  • 1 for each of the 3 arm movements (again 3 in total).
None of these solutions is perfect, once in order to achieve extreme playability from such Excavator, 4 simultaneous functions would be recommended (the 3 arm movements together with superstructure rotation). While this would be possible for the first option in the 2nd scenario, the manual lever is a major drawback for a fully remote controlled model. The alternative (1+2x3) offers just 2 sets of 3 simultaneous movements, which is also far from ideal.
We will see which of these, or if any other solution was chosen to control this model. Despite the 1+2x3 to be my preferred solution.

Considering that at least some motors could be shared between two functions and the respective most probable combinations, the logical place to have all them located would be inside the Excavator main body.
The first consequence from this, is that like in Jennifer Clark JCB JS220 Excavator, two functions would need to be delivered trough the model turntable. If it turns to be the case (most likely), it will be the second time such technique will be used into an official LEGO Technic model after a first appearance into 8258 from 2009.
It would then rests to know if the drivetrain will feature a Differential Drive or a Dual-Differential Drive (DDD). Although I believe the first option to be the one chosen, in order to maximize the power delivered to this large model (presumably heavy) and to make it move easier.

One comment also to the bucket... Since ever it seems LEGO is only delivering well proportioned buckets for small/medium sized excavators (8851, 8837, 8419 and 8047). Anything larger than these, like 8294, is getting wider buckets primarily designed for the LEGO loaders.
I believe this would have been also a very good opportunity for LEGO to give us a modern design from the old bucket (4700) used in 8851 and 8862. While this would make sense for official Technic models too, it would be of great use for many AFOLs trying their own Excavators and Backhoes MOCs.
Nevertheless maybe this can be an hint, for the yet unknown 8043 B-model, that we can expect. Another Loader.

After all, I still dream with a day when LEGO Technic releases a fully remote controlled Excavator, using pneumatic cylinders and more advanced pneumatic elements like PF electro-pneumatic valves. Thus avoiding the usual tethered pneumatic remotes. Such valves could however be also applied into a new generation from the wonderful 8455 Backhoe and many other models based on pneumatic elements…
But as far as it seems, the 8049 (Tractor with Log Loader) was the only pneumatic model to be offered us in 2010.

Can we now guess which where the LEGO Designers, behind each one of these models?
As for the price and partcount who makes their best guess too?  1800 parts... 2000?

Some new findings, may turn obsolete many from the above comments about the 8043 Excavator.
You may find worth reading, this newer post.

Last Update: 2009.Dec.26 19:45 CET

and finally, the 7939 / 7938: Power Functions Trains (from CITY Theme)

These are the first complete PF trains (out of the box) to be released by LEGO. They succeed the previous RC Trains system, which had already made a break with the “old” 9V Trains system, based on metalic and powered lines.
In 2009 we had a sort of "sneak preview” with the Emerald Night (10194) launch. This was mainly targeted to the AFOL segment and designed to guarantee from those, a good acceptance to the newly proposed trains PF system. However the EN does not include any of the PF elements required to motorize it, which must be acquired in separate kits. This is of course a strategy not suitable for the Trains in the CITY line, targeting boys aged 6-12.

Thus, the new CITY Trains include all the necessary PF elements for their motorization, as we can see from the typical PF orange band seen in the Passenger and Cargo Train boxes.
Each box includes 16 from the new flexible track system together with an assortment of track elements, which differ depending on the train set (Passenger or Cargo).
From the same orange band we can see there are also included one IR Speed Remote Control (8879), one Train motor (8866, the same used in former RC Trains), one PF IR Receiver (8884) and a battery box.
Once we can't see any image from the 10V DC Transformer (8887) on the orange band and the cost from a PF Rechargeable Battery Box (8878) would take a considerable part from each set cost, I guess the battery image is not what it seems to be... Hence I believe we have here being introduced a new PF element - A new type of PF Battery Box with the same form factor of the existing rechargeable version.
If this confirms to be the case, it might take Micro AAA cells, once 6x AA cells won't fit inside. Also it means that with the actual AAA rechargeable batteries available on the market, it would have a similar capacity to the standard LPF LiPo rechargeable battery (1100 mAh) and voltage (7,4V).

At least for some European countries, the expected train sets price is:
  • 7938: 119,95€
  • 7939: 169,95€

Eagerly waiting to know more and the summer to arrive, in order to play with the new Excavator.


Parax said...

So where is the 8041 truck/racer? Is it possible that this catalogue H1? or that 8041 is not h1 or h2?
or have lego changed to Q1/Q2 and Q3/Q4???

Conchas said...

8041 is more likely a 1H late release, or a specific toy store chain semi-exclusive.

Junkstyle Gio said...

The motor is surely going to be a must have for me!
It's a bit sad that it is red. I was looking and hoping for a different colour! (Yellow or Orange...)
More comments surely to follow!

Daniel said...

In the top left-hand corner of 8043, there are two small images showing what the excavator can do (like on all the other PF sets). When you zoom in, the top image clearly shows the three arm movements from a side view. The second image definitely shows the rotation (viewing from above the excavator), but there appears also to be a large white arrow 'underneath' the excavator, pointing in the direction of the tracks (just like on 8275 bulldozer), suggesting that this excavator could be fully remote controlled despite only using 2 PF handsets.

Judging by the shape of the box and size of the pieces relative to the model, I would say 8052 is a similar size (+price) to the 8292 cherry picker. 8053 is going to be much smaller than the mobile crane from 2005 (8241), and I have a feeling that the boom will be raised manually using a linear actuator (I think I can see a grey cylinder under the boom), rather than pneumatics. :(

It's disappointing that the excavator uses a pair of '4 x 4 Liftarm Bent 53.5' between the top linear actuator and the bucket, rather than using a realistic set-up like on 8294 (which uses two pairs of straight beams).

I will definitely buy 8243, and I will decide on 8052 & 8053 once I've seen the instructions.

Daniel said...

Do you know what the 8043 b-model is going be? (I would guess a tracked loader)

Anonymous said...

The 8265 is a 1100 part set.
IMO, the 8053 mobile crane is bigger than the 8265. And so, it have more than parts 1100 or 1200 parts (maybe 1500 or 1600).

Don't you think so ?


Conchas said...

Maybe, I'm using as reference the size from last flagships on even numbered years, whit just a slight increase.

Otherwise it would approach too much the biggest flagships 1800 partcount.
I don't think it has the size or complexity to justify such number.
However I won't be surprised if it have about 1300 parts. Maybe I get the figures in the post revised.

Anonymous said...

This is how I think the 8043 excavator will be controlled :

There will be one motor that controles 3 driving rings switches ( these 3 are linked and switching all at the same time ).
Now you use the other 3 motors for
A) 2 for the tracks ( 1 each ) and 1 for the turntable,
OR ( by switching using the first motor )
B) one for each arm movement ( again 3 in total ).


Anio said...

@ Jovel : I think that the excavator won't be controlled as you explained because you can't use the turntable and the arm at the same time. The model is remoted controlled and so it MUST have an excellent playability. :)


Sugarfree said...

What do you think, how much coast it Crane and Excavator?

falcom4 said...

sorry for my English, i thought "cost" but i wrote "coast" sorry :/

Anonymous said...

Okey, then give me a better solution. If you look close you can see gears in the bottom ( don't now the right name for it )
so the tracks must be driven by PF.

Anio said...

@ Jovel : Indeed, it seems there is a tan 20t on the chassis. So, the tracks may be driven by PF.
To have effective mechanisms (and so a playable set), mechanisms must be "simple".
So I would say :
3 M for the arm (as you explained)
1 M for the turntable
and 2 XL to drive.

BUT : it seems there is no XL on the box and only 2 IR receivers. :/

Maybe TLG will change the box, as they did with the 8258 (M => XL). Or maybe the tracks aren't motorized. :/

danogo said...

6 PF motors would be great but surprising.

Maybe allknowing Conchas is going to tell us in the still 'work in progress' details of the 8043... because judging by the other details, he knows more then the blurred pics can say :-)

Anio said...

@ Danogo : I had exactly the same impression when I read Conchas's comments on the models, but I dared not say ! ^^

Rob said...

Regarding the trains, Lego probably isn't including a photo of the transformer because it is different for each country. Given the high price of the sets, these may well include the new rechargeable battery. And yes, the box does say "batteries not included," but this could be merely for the hand-held IR control unit.

Efferman said...

I found the building instructions of the 8041 B-model on It seemxs the Race truck will com in the first half of 2010
part 1
part 2

Conchas said...


It would have been difficult to take one image from an angle, where the plug won't be visible for that purpose. ;)

Conchas said...


Great that you have found the missing instructions parts, from 8041 B-model. :)

LordGalewind said...

"First we get 4 models in a row for the 2H, what hasn't been usual. And lets see if you wont get another late model, like we did last year for the 2H and we also we will on the 1H2010 (8041)."

Hmmm...could you be hiding something from us Fernando?

All in all these are great looking sets. TECHNIC has really come to a point in the studless era where both function and style are both of good quality. I can't help but feel though, I've seen all this somewhere else though...does 8420, 8421, 8292, and 8275 ring a bell?

Conchas said...

No, I'm not hiding anything here!

It is just an association of ideas from the recent experience (2H2009 and 1H2010).
But it could perfectly not repeat, since we already have an impressive assortment for the 2H.

Anonymous said...

I also believe the excavator uses a studded turntable. In this case, it's harder to make but better.


arezey said...

Hmm. The Race Truck seems also something I need to get my hands on.. finally a good assortment of panels in an affordable set! Anybody else with me that the B-Model again seems better than the A-Model?

I'm especially drooling for those black panel plates... - *and* those wheels! :) Are those wheels completely new or have they been used before?

Conchas said...

I do prefer the main model.

The tires seem to be the same as in 4993.
If so, the wheels have been used in many sets, inclusive Technic ones, like: 8435, 8048, 8274, 8295,...

It looks the wheels are: 41896 (43,2mm D. x 26mm)

arezey said...

Dah - I did mean the tires, not the wheels... I always mix those two words up. :P
But then no - the tires ( are not new and have been used before.

Efferman said...

The best compromise to remote the excavator is imho the following method:
One motor per function of the Arm and Turntable, and a manual Switch who swir´tches between two Digging Functions and the Tracks. This would be the most realism with four M-Motors. but where is the Problem? Didnt we have not enough Motors and IR-Receivers at home? :)

arezey said...

"Didnt we have not enough Motors and IR-Receivers at home? :)" Absolutely not! Zero is nowhere near enough. :)

It seems I'm going to miss this flagship too... but hopefully will get some IR pieces from S@H. Hopefully.

So currently I'm out for 8046 Helicopter, 8047 Compact Excavator, 8049 Tractor with Log Loader, 8052 Container Truck and hopefully 8041 Race Truck. And also 8884&8885. :P
And maybe something else if I've got enough money left.

Anonymous said...

Im going to wager that there are three motors to control the digging boom and one motor that controls either the tracks or the superstructure rotation through a driving ring which is probably manual. Through some kind of clutch when the tracks move forward they are both engaged, and when they reverse only one is engages creating a turning motion. The (very grainy) picture seems to look to me like the tracks only turn one way and in reverse. This would solve the four motor dillema

Anonymous said...

There is a white arrow behind the tracks as well showing that it could reverse as well. Unless there is only one motor powering it, or that the two are on one channel then it would be safe to say that turning as well.

As for the Excavator itself, I would love to buy it if it isn't too expensive (well that is a huge factor) and whether there are any mechanical problems.

It seems to be the best excavator yet in the 'looks' department alone. I can hope that it can stand up to the gearing as well (My Front Loader almost burnt out my M-motor from stress alone)

Daniel said...

This set is going to be remote controlled, so there will definitely be no driving rings to switch between separate functions, because it would completely ruin the playability!

There will definitely be at least 4 motors in this set: 1 controlling superstructure rotation, and 3 controlling arm movements. I predict that the tracks will not be motorized at all, despite there being a large white arrow suggesting track movement. These are the reasons why I think this:

a)there appears to only be two receivers (I don't mean IR controllers) shown on the box.

b)there are no XL motors shown on the box, and M motors may struggle to move the excavator.

C)if PF XL motors are used, the number of motors exceeds the official 'limit' of the PF battery box (that is either: 2x XL or 4x Medium). 8275 did exceed the limit, but it was only possible to control a maximum of 2 XL motors at the same time, because of using only 1 remote. If PF XL motors are used in the excavator, it will be possible to control 2x PF XL AND 2x PF Medium at the same time, exceeding the official battery box 'limit'.

d)6 motors and 3 receivers would make this set very expensive.

Conchas said...


just remark b) makes think about.

mpj said...

My opinion about the excavator:

OPTION 1) it will not have motorized tracks...

OPTION 2) look at the IR Remote Control on the box. Are you sure is it the same IR Remote Control? Look carefully at the picture.

Conchas said...

Hi mpj, Thanks for the heads up!

I've zoomed it till 800% and it definitely doesn't look the same... ;D

Will write about in a separate post!

Andre said...

If the IR remote isn´t the same it´s good and bad...
It may offer new ways to improve playability and better technical solutions but on the other hand it makes the old IR remote control obsolete...

mpj said...

Anyway in my experience building a big fully remoted controlled excavator, the movement of the tracks is always very difficult, expecially with M motors.
So maybe there are "new" IR remote controls for better playability of the arm, but still no tracks movement...
Let's wait and see!

Gavin said...

Hi to you all. As the picture is not real clear it is hard to tell if this will have motorised track movement or not. However if you look at it a bit there appeares to be gears present inside the track srockets, they would not be there if there was no motorised drive, it was not done on 8294, so if this has not got motorised tracks then why do it?

Would it be possible also that two battery boxes are in use in this model? It would sort the motors per box problem as suggested by Daniel? Maybe two of the new rechargeable ones?

This is a very interesting development and maybe targeted at AFOL like they have in other lines, so the parts / price maybe higher than we have seen before.
