Features drive by a single cylinder engine, clutch, steering and front suspension.


This moc was designed to be shown at Fana’briques 2011, the most important lego exhibition in France. The aim was to built a “kinematic” moc in order to have parts in motion. The other aim was to have visible gears to get a more attractive vehicle. Consequently, the moc is powered by a single pneumatic cylinder engine which provides 1w of power (at 3 bars of pressure). The basic principle is based on old steam vehicles or tractors. Then, a remoted clucth by a small cylinder provides the power on the rear wheel (with the main chain). The steering is operated by the steering wheel in the cab with a 8t/screw and lever system (through the chassis). The front suspension is made with a flex part on a live axle. Finally I have had details like the centrifugal governor or the tank (which hides the Air-tank).


Concerning the driving, a hand pump with 4 pumps gives power to the engine. The engine runs smoothly thanks to the inertia wheel. The engine is quite reliable, during 3 days of exhibition, the engine have run without problem. Through this moc, I think the LPE moc is a good example for a demonstration of what it is possible to do in lego (such as in an exhibition).

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