Hi! I present my entry to the Rebrick Porsche contest, a 962 C Le Mans racecar. In this moc I tried out some newly developed techniques. I was happy that I could finish it before the deadline, many, many working hours, days, "sleepless" nights were required to make it. If I had to choose, the 962 C is my dream Porsche, it exists. A legendary Le Mans racer, the first race car with real ground effect, and a road version was also produced in the nineties. I tried to design everything to represent the real car, both esthetically and in functionality. I put every information, explanation into the video, so here I list the main features: - Full independent suspension, in the rear with rocker arms and angled springs - 4 speed sequential transmission with indicator in the cockpit - Automatic friction disk clutch - works when a gear change happens - Working front brakes with small pneumatic cylinders and air tank - Brake pedal works, too - Openable doors and removable rear cover - HOG steering and working steering wheel - Kingpin inclination, Ackermann geometry - Real boxer crankshaft (instead of 180°V) Details: Antenna, interior, engine, turbos, rear view mirrors, headlights, windshield wipers, fuel caps, fire extinguisher, instrument panel, radiators, etc. Video: Pictures: Gallery: https://www.flickr.c...157668905453474 Hope you like it. Comments, questions are appreciated, as always.
I everyone, I start a WIP topic to show you frequently my progress on the Bugatti Chiron. Here we are. I wanted to create a new supercar (or megacar) before I finished my dual clutch gearbox. I love Bugatti brand and the new Chiron is so beautiful so I decided to create and design this car in Lego. I don't have finished instructions of the gearbox because it's very long :( All the features attended : A 7 speeds + reverse sequential dual clutch gearbox ( You can't see it on the picture because I'm working on the instruction) It's placed under the w16 engine Variable hight suspension on the front and on the rear Working pfs direction 4x4 transmission Working spoiler A manual gearbox to select between two rc functions (move the spoiler or move the suspensions) A global clutch to disconnect the car from the 4 L motors pfs. Typically ti will be possible two switch between a manual and a RC mode A hog for the manual mode Manual doors and roof I will add the real specifications soon. So, what I've already done now: The new dual clutch gearbox Rear axle Front axle Under chassis A mini functions gearbox 2 speeds W16 realistic motor The global clutch transmission I decided to begin the global design of the car because it the most difficult to create IMO just after the working transmission :) When I will be satisfied by the design, I will add the missing features and add others maybe. I think It's the best way to build a supercar. If the design is bad, even you have the best mechanic created, nobody care. I choose blue obviously ;) I've already ordered a lot of blue pieces on BL. Stay tune and do not hesitate to comment ;)
Hi everyone! This is my first MOC. Besides the gearbox, it´s my own design. 4 RC functions: 1. Drive (L-motor) 2. Steering (L-motor) 3. Cabin tilt (L-motor) 4. Sequential gearbox N+1+2+3 (Servo-motor) The gearbox is a modified version of a gearbox constructed by DurianObried. The shift mechanism is a modified version of Jaco4´s design. It works very well and shifts gear fast. Front and rear suspension, small turning radius and working steering wheel. More pictures on Brickshelf. http://www.brickshel...ry.cgi?f=565719 Here is a picture on the gearbox shift mechanism. To the left you can see the servomotor shifting the gearbox.
I just found a way to do a shifting system witch doesn't use any rubber band. Basically , it's the same system as my Porsche 919 but I replace the bands by these connectors. Some people don't like having bands inside a car (including me ), so this allow even more possibilities. The system is really reliable and works really smoothly.
