  1. I'd like to share my most recent model - 1:10.5 replica of 1969 Ford Mustang Boss 429. Boss 429 was the high performance variant of first generation Mustang, equipped with a powerful 7.0 V8 engine. Only 1359 were made, and now there is one more :D

    Watch it in all its glory:

    Functions:

    • RC drive - RWD with differential, 2x L motors
    • RC transmission - 4 speeds, sequential, M motor
    • Detailed V8 engine replica with fan connected directly to propulsion motors
    • RC steering - with moving steering wheel, M motor
    • Front suspension - double wishbone
    • Rear suspension - floating axle
    • Openable hood with lock controlled from the cabin
    • Openable doors with locks
    • Openable trunk
    • Adjustable seats (sliding forward - backward and seatback angle adjustment)
    • RC front lights

    Please watch the video to see this machine in action and for more details.

    I am quite happy with how I managed to include all the functions without compromising on proportions and interior in a relatively small model (46cm long). The biggest challenges were to fit piston engine over the suspension with the blue air intake under the hood without lifting it (as the result I had to make the hood hollow below the external air intake but still it was tight) and to fit interior over the gearbox. For that purpose I made the transmission very flat with gear shifting shaft actually crossing the drive shaft... (can be seen in action in the video - 2:30)

     

    I hope you liked this model.


  2. After 42099 and the whole new PU system, I'm here with a MOC that uses something a bit older - RC system. After all these years it is still the most powerful 100% LEGO solution.

    Watch it in all its glory:

     

    Features:

    • RC drive - 2x RC motor, geared 3:1 (slower output)
    • RC steering
    • Front suspension - double wishbone, soft, long travel, positive caster angle, 7 stud ground clearance
    • Rear suspension - floating axle, soft, long travel, 5.5 stud ground clearance

    Please watch the video to see this machine in action and for more details.

    I hope you liked this model.

    The drilling rig is able to lower itself under own power, but to lift the rig it needs a little help (from a crane...) to hoist it past the dead point of the LA's. When the rig is past that it can be lifted under own power.

    Maybe you could add an aditional LA, even small, at a different angle. It could be used only at the beginning of lifting process. At the next part of lifting it doesn't have to be connected at all. What do you think?


  4. I' ve made a scale model of semi-trailer truck with a trailer. It's in 1:60 scale, so wouldn't look out of place in a minifigure scale Lego City. But it is remotely controlled.


    Video:


    Functions:

    • drive (truck RWD) - L motor
    • steering (with right geometry) -  Servo motor
    • remotely openable trailer's cargo door - M motor


    Everything is controlled remotely using SBrick, powered by standard 8881 battery box.

    Internals of the trailer, door opening mechanism, battery box and sbrick were packed here:

  5. I' ve decided to make an alternative model for 42054 CLAAS XERION 5000 TRAC VC set. I' ve wanted to design something different from all those excellent c models already made, so I made a truck capable of off-road conditions, with crane and many other functions. 

    The result:

    Functions:

    • rear axle drive with 4 piston engine
    • steering
    • live axle suspension
    • side outriggers
    • cabin tilting
    • rear PTO (power take off)
    • crane arm rotation
    • crane arm 1st stage elevation
    • crane arm 2nd stage elevation
    • grabber closing/opening

    Please watch the video to see this machine in action and for more details.

    Main.jpg

    This model is powered by one m motor with rotation direction selection. It powers main selector, crane selector. and PTO. Main selector switches between worm gear powered functions and arm rotation. When worm gear functions are selected, there is another switch to choose between outriggers and cabin tilting. The crane selector switches between 1st and 2nd stage elevation.

     

    I had to use some interesting (I think) solutions because of parts selection in 42054 set:

    Piston engine

    There are no piston engine parts in the set, so i made them from some connectors. You can see it working in the video.

    Suspension

    There are no shock absorbers or wishbones too. So I' ve made a suspension based on twisting axles:

    susp1.png

    Every wishbone is suspended independly. 3 of those connected to axle make a well-working long travel soft off-road suspension:

    Grabber

    There was a grabber in original set, but when building the grabber I've already used the worm gear for more important functions, so I' ve designed a different locking mechanism:

    grab2.png

    Turning the green axle makes the red grabber frame move up and down and becouse of engaging the blue knob gear with h-frame opening and closing blue grabber.

    Instructions are already available here on rebrickable!

  6. I' ve made a model of a Snowmobile. I've tried to make it as detailed as possible.

    Video:


    Functions:
    - Driven tracks (L motor)
    - Steered skids linked to handlebar with Ackermann geometry and positive caster angle (M motor)
    - Front double wishbone suspension
    - Realistic rear suspension

    Everything is controlled remotely using SBrick.
