TT Monster Truck

A small and powerful truck powered by PFS. Including building instructions.


After building my Lada Niva, I have chosen to improve the drivetrain and the problem about the friction on axles. The main problem was the weight. Without U-join, we mustn’t have a lot of weight, thus I chose to reduce the weight at the minimum, I couldn’t do that on a truck such as the Lada, so I developed a new truck,  lighter and smaller. Considering the small available width, I have chosen to keep pendular suspension on the rear but put a rigid axle without suspension on the front.


The truck is powered by a PFS XL motor with 12/20 12/20 reduction (approximately 1 km/h). The steering is operated by a M motor with a worm gear and a lever, no rack pinion. The fake engine L2 is placed under the bonnet and is driven by the front axle. The final weight is 900g, that is not enough to generate lot of friction on the steering axle (also driven axle). Therefore, the drivetrain is very powerful and effective (TTools said 0.43 in general and 0.96 for drivetrain) and without U-join (in order to prevent the broken U-join). I have also put lights from e-Lite kit.

The building instructions are available. You can watch them by browsing my webiste or

    just finished building this and it is AMAZING!
    cant wait for the next trial truck with instructions!


    Hello, having the picture one by on is a personal choice which enable me to control the broadcasting of my work. So I won’t create folder such as MediaFire. Nevertheless for the HD instructions, I provide for you a PDF which group all rendering. You can also watch the instructions at Brickshelf and use Brickshelf Backup software to download a whole gallery. To finish, If you read the FAQ, you will know that I don’t create instruction if the moc is more than 2-month old, that is the case here. Regards.

    Hello ,

    Can you make the building instruction in a folder to MediaFire.
    I think that everyone will prefer it from watching the photos to the web one-one.

    Am i able to transform it a little.Personal use onle.

    Thanks you very much.

    Bonjour !

    Je suis fan de vos créations. Et j’aimerai parler avec vous à propos des trial trucks en LEGO. Prenez donc mon adresse MSN s’il vous plait 🙂
