Ever since I took part in ACC races at the latest Lowlug meeting,I've become addicted to racing with self-made LEGO-racecars. First I made a very simple RC chassis x2(which was really ugly), and improvised a race-track in my own attic. There I raced against my brotheruntil the batteries were completely empty. So I just had to make small racecars that would also look nice. This is the first in a series of at least 2 small racecars. The drivetrain is derived from my E.R.T.W.D..And in contrast to my previous RC car, the Little Devil, it features return-to-centre steeringwhich makes the car more controllable. It uses thetechnic axle connector rectangular triple spring-loaded to return the steering axle to neutral position. Although it was built as small as possible, I did manage to include quite some featuresof which the rotating steering wheel is my favorite. It also has working frontlights and rearlights. The doors can be opened. But they have a small lock, so they won't open during driving.
The trunk opens as well, giving a nice view of the drivetrain. Since it has to endure some racing-abuse, it was made as strong as possible.And to protect the front, the bumper was fitted with shock-absorbers. So driving this thing and crashing into something (which happens regularly) is pretty safe. The choice of wheels was a consequence of a number of aspects: initially all the wheelswere of the 62.4 x 20 S type, but this resulted in weird-looking cars with wheels that were to big. So I switched to model team wheels for the front. But I kept the big rear-wheels because smaller wheelswould require more gearing in the drivetrain. Eventually the big wheels give it a powerfull look. Some technical data:Lenth: 38 studsWidth: 17 studsHeight: 14 studsNumber of parts: 728 (including the remote controller)Drivetrain: XL-motor with 3:1 speed increase. I've made complete step-by-step building instructions.They instructions can be downloaded from the Yellow racecar instructios-page.

Winners will be chosen purely on the number of votes acquired.A LMP1 Race Car built for the Techlug Contest #27, featured suspensions, fake engine, steering, openable doors and rear bonnet with nice bodywork. The Contest of Techlug #27 was opened on the 1th February 2015. I hesitated for a long time to participate because I was a kind of bored by car and it was not my favorite subject so far. But after watching some pictures about prototype on LMP1 Race Car, slowly I decided to participate to see what I can make and what I can propose. Here are the basic expectation and rules for the contest : The basic idea is to make better than the #42039 Lego LMP1 regarding the bodywork and design.
Then I have started to build the chassis using special suspensions as real LMP1 Car, and next make the bodywork, with plenty of work on it, I manage to make something nice and homogeneous I think. The contest focused on the design, I have implemented the minimum for the functions : Engine, suspensions, steering and openable parts. The front axle is equipped with double wishbones with suspensions inside the frame and connecting rod. When the suspension is compressed, the connecting rod makes rotate a lever which pushes the shock absorbers. This system is the same as real LMP1 Car and is nicer than the shock absorbers directly connected to the wishbone. It enables me also to have a very thin suspension and makes a lower design at the front, contributing the sportsmanship design. Next the rear suspensions are based on the same principle. A connecting rod is connected to the lower wishbone, which makes rotate a lever connected to the shock absorbers. The difference is as I have not enough place to place the spring in the same position, I have placed them perpendicular to the rear.
The engine is connected to the rear axle with a differential and 20 tooth gear, then a 12th gear and two 16t/16t gears. The engine is directly connected to the rear axle. The steering is also simple, a rack with a pinion is connected to the HOG with bevel gear. Note that there is also a return to the steering wheel with 16t spur gears and U-join. This connection has been removed for the Contest due to the amount of parts and because it has been considered as an exotic function. In any case, for the instructions, I have reestablished it. Now we arrive to the interesting parts, the openable doors. This openable doors look like similar to Lamborghini style. They are controlled by the rear liftarm on each side. This liftarm is connected to a long connecting rod which is connected to an other lever with a 5L ball connecting rod attached to the doors. Then the doors is attached to the chassis with a perpendicular connector which enables the doors the lift up and slightly move on the righ or left.
This details about doors is very nice to see, and all connecting rod is equipped with friction pin which allows the doors to keep up. Concerning the rear bonnet openable, it is made with one part which can rotate on the rear near the air intake. A system of liftarm with friction pins enables the rear bonnet to not fall and the rear and be set up. Note that all rear bonnet can lift up, including the wheel arch raises to. The bodywork and design have been the most difficult thing to do. I have tried to have a visual identity with nice shape, and homogeneous design (shape colors choice of parts). The first has been the front face which makes the identity of the car. I have start to choose the front bumber with many connectors and middle bulge in black. Then a white hood with plunging shape and on each side the light which are surround by flex. Consequently the front face is aggressive but with smooth and curvy design. Then I have designed the middle side. I have tested many possibilities, but the better was this simple panels 5×11 which make a nice slowly slope which is connected to the rear wheel arch.
Underneath this side, there are two panels, one for making a intake and other to surround the shape. This slow slope is one of the visual identity of this creations, and has received many congrats for people on forum and youtube. At the rear, I have continue with ther flex arch build with flex and 5L beam which is connected to the rear panel. I have added a big air intake underneath and 4 exhaust pipe. The global design is surrounded with a line of connector in black which break the empty place. Two small red ligh is placed under the big 3×11 curved panels and a big wing with central pole in white. These shapes and part give a nice design to the rear face despite the relative simplicity. Note that the exhaust pipe remain stable when the rear bonnet is opened. The rear bonnet shape is connected to the cockpit with a curved slope with white panel. Concerning the empty space between the shark wing and cockpit, I didn’t succeed to find something nice and homogeneous to fill this empty place so I have chosen to make this empty space useful to see the engine running.
That is why I have added a white flex, in order to suggest a glass wall. The cockpit is quite standard, it is made with curvy white panel and is connected to the windscreen and then attached to the front white panel on the hood. I have chosen to make the windscreen with connectors, in order to have maximum rigidity to have a real survival cell. I have also chosen to have a windscreen and global design regarding the shape and smooth (not sharp line, big appendix and so on) because my inspiration was not the last LPM1 RaceCar but some GT car or old LPM1 like the Toyota GTone of Nissan R390. That is why I have not chosen to reproduce the cokpit and windscreen of recent LMP1 car (very thin, like a water drop) but with GT style. I have made the building instructions as a 119 pages PDF with photo sequence. Including Bil Of Material at the end. Then I have contacting the excellent Thorsten Speltz who have already made some instructions for me including the Citroen 2CV or the Honda RA 300.
He has made an awesome work for the building instructions ! Therefore, I can propose you two versions of the building instructions, A buying version with professional looking instructions made by Thorsten Speltz, and a free photo sequence instructions. Both will enable you to rebuild it, but buying the professional looking instructions is the best way to support my work an Thorsten Speltz to ! See as jpg file from rebrickable : Or in jpg file from computer rendering : You can also see it and download it in HTML table : Or check it online with rebrickable : By using the next up paypal button, you will get the building instruction in PDF (35mo) for 5€.
