Here is my next model, a 1:10 scale replica of the BMW X3. This model was made as a non-exclusive commission. It is my first model that uses SBricks to control the model.

A view with the iconic grille

My customer wanted to have a model that would have both a manual mode as well as an RC mode. And since the BMW X3 is a four wheel drive car with multiple drivetrain settings he would like to get that replicated as well. So inside there are four motors that are used to drive (2L motors), steer (1 M motor) and select the drive mode (1 servo motor).

The drive modes that can be selected are:

  • manual mode
  • rear wheel drive
  • rear drive with driven center differential (effectively giving a 75-25 power distribution between rear and front axle)
  • four wheel drive

Next to the motors the model is also equipped with eight LEDs for the front and rear lights. The outer LEDs function as indicator lights as well as normal lights. Everything is controlled through an SBrick profile on your smartphone.

PDF Instructions are available in my webshop. JaapTechnic has made stickers for this model, these are available on his website. The partslist can be found on Rebrickable. A custom profile for the SBricks can be found on the SBrick site.

Large helicopter


I’d like to present my latest model. This time it is large motorized helicopter. It has a rotorspan (if that is a word) of one meter and also the body is one meter long. It has all the controls that you expect in a helicopter:
– Collective pitch control
– Cycling pitch control
– Anti-torque tail rotor control

Side view with the doors closed and landinggear retracted

The controls can be operated manually either from the cockpit (cyclic sticks, collective levers and anti-torque pedals) or through small HoG knobs on the rear underside of the main fuselage. It is also possible to add four servo motors to the model to control all these functions remotely via IR.

Furthermore this helicopter is equipped with a retractable rope at the side, a fully articulated camera/searchlight under the nose and a retractable landinggear. All these functions are motorized as well and remotely controlled via IR.

The camera/searchlight in the front can rotate 180 degrees side-to-side and 360 degrees front-to-back

Finally the doors in the front can open as well as the sidedoors that can slide backwards to give access to the spacious interior. When closed these doors sit completely flush with the fuselage.

The model is so large that it is difficult to get proper photos of it, that’s why I chose in this case to only show renders.

Instructions for this model can be bought in my webshop. The partslist can be found on Rebrickable. Please note that the four servomotors and two of the IR receivers are only needed if you want to have motorized flight surface controls. If you are fine with manual flight surface controls you can omit these motors. You’d still need the four M-motors and the remaining two IR remotes and receivers to control all the other functions.

Finally, be warned that unauthorized reproduction of this model, its instructions or its pictures is illegal and you run the risk of being prosecuted for it when you do it anyway.

Bladerunner spinner


Time for a post on a quick model I have finished some time ago, but didn’t get around to post about. It is the Spinner of the movie Bladerunner.

Bladerunner Spinner
In fly modus

The model is motorized with three functions:
– Opening left door
– Opening right door
– Switching between fly modus and drive modus

The last function is actually a bit more intricated. It consists of the following movements:
– First the covers around the front wheels move outwards
– Then the covers rotate 90 degrees
– And at the same time the front wheels come down

In drive modus with open doors

I also made a video of it.

Instructions are available in the shop.

Liebherr LTM11200


After nearly 10 months of hard work I am finally able to present the LEGO Technic replica of the Liebherr LTM11200 crane. It is one of the biggest roadworthy cranes in the world and I have tried to do it justice in LEGO as well.

This is actually a redesign of the model I made in 2013. At that time I had designed the carrier, the superstructure and the outer section of the boom. I have gone through the entire design, updated it to improve on the weak points of the original design and updated it to the newer parts that are now available. I also designed the complete boom from the ground up.

When I started this model I wanted to make it the most complex remote controlled model that I could think of. At the same time I didn’t want to exceed the limitations that the LEGO PF system set. Which meant no more than 8 motors could be used in the model.

They are equally divided between the carrier and the superstructure. In the carrier one motor is used for switching, whereas the other three are used to drive different functions depending on the position of that switch. It has two positions. In position 1 the three motors are used for driving, steering and switching the steeringmode (you can steer normally, or you can crabsteer). In position 2 the three motors are used to expand the outriggers, elongate the outriggers and finally extend the outrigger feet.

In the superstructure a similar setup is used, only this time there are four positions for the switch. Which gives 12 different functions that can be remotely controlled. Of these 12 functions 8 are located in the superstructure itself:

  • Rotating the superstructure *
  • Raising/lowering the counterweight
  • Raising/lowering the hook
  • Raising/lowering the boom via the cylinders
  • Raising/lowering the boom via the rope-and-pulley system
  • Raising/lowering the arm of the operator cabin
  • Rotating the arm of the operator cabin
  • Tilting the operator cabin

And 4 functions are routed onto the boom:

  • Extending the 4 section boom *
  • Spreading the stabilizer arms
  • Tilting the stabilizer arms *
  • Raising/lowering the supporting legs (needed in case the boom has to be transported separately from the rest of the crane)

This model was always intended to push the edge of the possibilities with LEGO Technic. And unfortunately that edge pushed back. The model is incredibly complex (as an example: it uses over 300 gears) and doing all that in plastic proved to be too difficult for some functions. The functions with an asterisk require manual assistance when operating. And believe me, even though lifting the boom is possible by combining the cylinders and the rope-pulley system, it is really scary to see how much force is going through all that plastic.

Nevertheless, I feel that this model does not meet my quality standards. I therefor decided that I will offer instructions at 50% of the intended price, which means you can buy the instructions for 37.50 euros instead of 75 euros. You will be able to pay full price for the instructions if you want to encourage me to keep pushing the Technic boundaries with my upcoming models.

A big thank has to go to Merlijn Wissink who spend a huge amount of time on making the instructions. The instructions are done to LEGO standards and fill a book of 1174 pages. We did our best to make sure that every step is clear, but as you can imagine I might have missed something. Please let me know if there is anything unclear and I’ll try to explain what was intended.

The partslist on Rebrickable was also compiled with the utmost care, but also here errors could have been made by me. If you find out there is a piece missing (or too much), please let me know and I will update the list.

I hope you enjoy building and playing with this model as much as I did designing it. The end result is a nearly one meter long mammoth that can reach up to 2.5 m high. It is by far not the biggest crane made out of LEGO Technic, but it sure is one of the most complex.

Leg godt,

Alfa Romeo 4C Spider

Alfa Romeo 4C Spider

The inspiration for this model came from a colleague of mine who purchased the Alfa Romeo 4C. I searched the internet for pictures of his car and then I found this spider version in gorgeous white with Italian race stripes. For some reason I can’t phantom now I thought it a good idea to make the car fully remote controlled.

The Alfa Romeo 4C spider has the following features:
– Independent suspension on all wheels
– Openable hood/hatch/doorsar4c-007_
– V4 fake engine
And the following functions are remote controlled:
– Drive
– Steering
– 4 speed sequential gearbox
– Seats forward/backwards
– Seatrest recline forwards/backwards

I have made instructions for this model that are available for free (but be warned that this model uses a lot of rare parts). On the building instruction page you can order the instructions.


Here is a video which shows all the functions.
