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.

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.

1:10 scale Pagani Huayra

A red and black beauty with medium stone grey accents. Breathtakingly detailed and packed with functionality. Released as an exclusive limited run of only ten sets. Delivered in a high quality German packaging container. Here is my latest model, a 1:10 replica of the Pagani Huayra.

The Pagani Huayra

This model is like no other model. It has over 2700 parts. It features an 8 speed gearbox that is controlled through the gear shift stick in the center console in exactly the same way as the real car. It’s clamshell bonnets can open to reveal the cantilevered suspension setups on all wheels. A detailed V8 engine sits in the back, surrounded by all the tubing and piping to feed air and fuel to this hungry monster. Hand of god wheels are placed discretely in the model to operate the chairs, the gearbox, the steering and the drive height adjustment of the front wheels.

The aerobrakes in the front and back are moving like the real car when going through a corner. In every part of the car the design is replicating the details from the real car. From the iconic ellipse-shaped front lights to the quadruple exhausts. The interior is decorated in warm, dark hues of brown, grey and gold. The chairs are fully adjustable.

The model uses flexaxles in abundance to recreate the smooth curves of the original car. Despite the curves and angles in the bodywork the model is extremely stiff and can lifted by the roof without fear of it breaking apart. The stiffness of the structure is generated in the same way as the real car through a monocoque structure surrounding the cockpit.

The smooth lines running from the front to the back are clearly visible in this shot

The instructions will be printed in full colour on glossy paper, while the parts will be packed in a high-quality German storage system. This set is limited to ten copies due to some of the rare parts used in this model. It can be ordered through the webshop and will be delivered with free shipping.

F14A Tomcat

With the lockdown keeping us all confined to our homes giving us way too much spare time I decided to release the instructions of the Tomcat I built a couple of years ago. At nearly 4000 pieces and with a myriad of functions it is a build that will keep you occupied for quite some time I hope. You can buy the instructions in my webshop. When you have two sets of 42066 you’ll have about half of the pieces needed to build this model.

I wrote a longer article on all the functions here, but here is a short summary of the functionality:

  • Motorized landing gear
  • Motorized landing gear bay doors
  • Motorized Gatling gun
  • Motorized onboard pneumatic pump
  • Motorized swing wings
  • Motorized cockpit canopy
  • Pneumatic arrester hook
  • Pneumatic air brakes in the wing and on the fuselage
  • Pneumatic leading edge slats
  • Pneumatic intake bleed doors
  • Pneumatic delta wings
  • Pneumatic switch to choose between the inboard pneumatic pump and the of board manual pneumatic pump
  • Manual joystick that is connected to the control surfaces
    • Differentially operating elevons
    • Both rudders
  • Manual ejection system. This will eject the canopy and the two chairs

Stay home, stay safe.

Liebherr LTM11200 WIP


Time for another update on my Liebherr crane. I have made a first version of the 4 stage boom. The thing is massive! It weighs over 4 kg, it has 90 long panels (3×11 curved, 3×11 flat, 5×11 flat) in it and it reaches 2.5 m when fully extended.

This is the fully extended position

Due to the weight it is now impossible to lift the boom with just the cilinders. So I added a system with rope and pullies to lift the boom. There is some fearsome bending of axles in the current setup when the boom is lifted, but it works.

I devised a new way of extending the boom to maximize the size of the inner sections, but also this system is struggling with the sheer weight of it all.

Rotating the superstructure has also become impossible with out a helping hand.

On the plus side, the whole crane can stand on it’s own when fully extended, which is an awesome sight. Also the speed of the ropes is not as slow as I feared.

Even though it looks finished, it is not. There are still quite some things to improve:

  • The rope for lifting the boom and the extention of the cilinders need to go to the same group of RC operations (if you remember there are 4 sets of 3 functions each in the superstructure).
  • A driving mechanism for extending the inner sections needs to be made that is strong enough (at least it is self braking now)
  • The structure where the pulleys in the rear are connected to needs to be strengthened (there are even some form-locked constructions that are being pried apart)
  • The stabilizer arms need to lift further upwards
  • The small LA’s in the stabilizer arms need to be replaced with big LA’s (that will bring the total amount of big LA’s in this model to 12)
  • The rope for the hook needs to be properly guided along the boom
  • The legs to put the boom on when moving the boom from the carrier to a transport wagon need to be designed and added

Here is the heavy road configuration version (without the extra pulleys to lift the boom):

Finally I am pleased to announce that the work on instructions has started. So please stay tuned.

Leg godt,
