    Audi R8 Spyder RWD - 42083 B model

    Thank you all for the nice words :D You are right about the side line, espesciallly at the rear. In real Audi the whole rear descends under a low angle, in mine only the engine cover. The limitation were the flat mudguards and the convertible roof mechanism, which took a bit of place. Yes, you are right. I want to make a RC version in dark blue. I think yes. If you remove the gearbox, there would be enough place for motors and worm gear with the clutch gear.

    Audi R8 Spyder RWD - 42083 B model

    Thanks :D Yeah, the two tones color was an impediment. After designing whole car I changed color of few elements to make it look more consistent.
  3. Audi R8 Spyder Specifications Length/width/height: 71s / 29s / 18s (57/25/25 cm) Scale: 1:8 Weight: 2293g Parts: 2701 Features Front and rear independent suspension 4-speed sequential gearbox Working V10 engine RWD Steered wheels by HOG Working steering wheel Convertible roof Openable doors, hood and engine bay A suitcase in the trunk Recently, a lot of alternative models have been created, so I decided to make mine :) I bought the 42083 in last year. I am big fan of automotive and supercars, so for me it was obligatory. After building the main model, I thouht that it would be cool to build something else. I set myself few goals: use only the parts from the set, improve the suspension and transmission (in Chiron it doesn't work perfect), reproduce reasonably realistic look and make a working convertible roof. At the beginning, I was building the Lamborghini Huracan. I built the chassis and the rear part of bodywork, but when I started building the front it was really hard to model it. In the Huracan the front nose goes really low, with a large angle from the bonnet. With using Chiron's mudguards there was a huge hole between them and the nose. It wasn't looking good, so I decided to make a different model. I haven't had to think long. Lamborghini Huracan and Audi R8 are quite similar. They belong the same group, both have V10 engine and similar dimensions. I started the building of Audi this time from the front, it looked quite good, so I was continuing the building of Audi R8. Here are some WIP photos. The car has steered front axle, by using the HOG with working steering wheel. There is no AWD, so the steering radius is quite good. In the front and in the rear there is independent suspension, in both based on liftarms 1x7. This is due the fact that with longer wishbones there is bigger leverage and the suspension is stiffer. For this reason too, there is no Quattro transmission, short wishbones used in Chiron create too little leverage, and trying to extend them ends up with a colission of the inside part of the wheel with the wishbone. Under the fake V10 there is a gearbox with "only" four gears. This is due to use the driving rings as a exauhst tips and maximum lowering of the V10 to place above it the roof. In my opinion more gears doesn't make sense, beacuse in 8-speed gearbox you can't see the difference in rpm of the pistons between next gears. The gears are changed sequentialy by a lever in the middle tunnel. In the mechanism there is a lock to prevent shifting from 1st to 4th gear and vice versa. The system of the gear change works on similar principle as in other MOCs of supercars - Charbel's McLaren 720s or T-Lego's Lamborghini Centenario. I think that this placing of the lever is better to use than the paddle shifters, esspecially that there is no roof. I think that the best feature is the convertible roof. Designing appropiate geometry of movement of the roof and engine cover was quite a big challange. I started the work from designing the movement of the roof itself, which had to avoid the seats. The next problem was the engine cover, which firstly had to move while opening the roof, and secondly I wanted to make it openable to show the engine bay. At the end I had to synchronize both movements so that the both elements do not block each other. The roof and the engine cover slide out with using some links, built from liftarms and connectors. The whole convertible roof mechanism took me above two weeks. While building it was important to me to replicate the details well. In the interior there are pedals, air-conditioning and at the driver's side a wall in the middle tunnel. In the real Audi R8 Spyder you can not look inside the engine bay, there is only a little cover at the end of the car, where are the basic fluids. However, I made openable rear cover to show the fake V10. I tried at my best to build the engine bay, and under the rear cover there is even an oil plug :) Chiron comparison. Thank you very much to Audi Poznań Franowo ASO for the interest and allowing me to take few photos with the real Audi R8. I am happy with this model. Despite limited amounts of parts the car is not bad. I plan to make a RC version in one color. Don't forget to watch the video! The Gallery Rebrickable

    Thanks for all the nice words ? You are right, they are the only one for a normal, non-supercar vehicle. There are also 94.3x38, but they fit to a much larger scale.

    Yes, the polski fiat is Fiat 125p. There is also Fiat 125, which looks a little different (square front lights instead of round ones).

    Fiat 125p

    Fiat 125p Specifications: Length/width/height: 58s/23s/20s Scale: 1:9,5 Weight: 2268 grams Parts count: 3066 2x L motor 2x servo motor 1x sbrick Power supply: 1x8881 BB/1x8878 BB/1xBuwizz Features: Driving - 2x L motor Steering - servo motor 4-speed gearbox - I (1:2,08) II (1,67:1) III (1,25:1) IV (0,8:1) Changing gears - servo motor Front independent suspension Rear floating suspensionWorking inline 4 cylinders engine Working steering wheel Adjustable front seats Openable doors (front with lock) Openable bonnet from inside Openable trunk Removable bodywork Front and rear LED lights I came up with the idea of building Fiat 125p at the beginning of this year. I started the build in the March, and after two months the model is ready. For driving I used two L motors, which powers the fourspeed gearbox. I wanted to make it as low as possible to have enough space for interior. Apart from the gears it is 2 studs high, thanks to use the Chiron’s orange brick. The gears are changed using servo motor and a simple stepper. Gear shifting is reliable in 80% cases while driving and 100% while it's stoped. This is probably due to friction while driving. Most often second gear does not want to shift to third. This gears are on both sides of the gearbox, it probably results from that. I changed axles and lubricated the driving rings, but the effort was the same. Gearbox ratio: I 2,08:1 II 1,67:1 III 1,25:1 IV 0,8:1 The car drives quite smoothly. In the fourth gear it reaches 4 kph, while powering by buwizz in ludicrous mode. For steering there is servo, which also moves the steering wheel. What I chose as one of my goals was removable bodywork. It required a slighty different build of the chassis and completely different build of the bodywork. The most important was to route the wires correctly from the front of car (2x L motor, servo and lights) to the rear, where there is sbrick. It required using two extension wires 20cm and 50cm. Time for manual functions. Fiat has got front doors with lock. It has similar construction as in my previous MOCs, it works thanks to a rubber. The front seats are adjustable in probably the easiest way. There are no any worms or gear racks, the adjustment works thanks to a lever, which moves the seat. It works similar to wishbones in suspension. On the passagner’s site there is a lever to open the bonnet. Unfortunately on the driver’s side there wasn’t enough space, due to the steering wheel and wires. Bonnet and trunk has got hinges to prevent it from falling down. While building the bodywork the most important was to provide it with adequate rigidity, because it is another part. The roof gives the stiffness, which (first time in my MOC) performs the function of strengthening the body work, just like in a real car. Most of the work was with the body line. Looking from upside on Fiat, it is a bit rounded: narrows at the front and rear of the car, and widens in the middle. I solved it through not entirely legal connection: liftarm 15 at slight angle. The door frames also required a little bit of effort. I tried to use as few as possible this, because of it’s terrible price in red. Curiosities: 1. The pistons are moving in the same order as in the real engine. 2. The air filter also bolts the body to the chassis. After turning it the lock in the front is released, and after removing axles in the middle and in the rear, you can remove the whole bodwork. This is the first model to which I made instructions. It required some patience with stud.io and LDcad.

    Liebherr HS 8040

    Thanks for kind words :D

    Liebherr HS 8040

    Liebherr HS 8040 Specification Length 40s / width 23-29s / height 21s (32/18-23/17 cm) – without boom Scale: 1:18 Maximum height depending on the lenght of the boom I 70 cm – equivalent 11m II 87 cm – equivalent 14m III 102 cm – equivalent 17m IV 121 cm – equivalent 20m Weight: 2945-4014g Power supply 2xBB 8878 Controlled by two sbricks 2x M 3x L 2x XL Functions Driving - 2 Ls Track sliding - M Rotation of the uppercarriage - M Lifting boom by a winch – L Two winches for moving the bucket – 2 XLs Today, I’d like to present you a dragline excavator Liebherr HS 8040. I came up with the idea of building such a machine after watching a movie from Brick Creek exhibition. The whole construction was made in about two months. For driving I used two L motors, which power both tracks with ratio 1,67:1. Because of that ratio the excavator is pretty fast (maybe too fast for such a machine). Because of variable track spacing there is no space to add other gear reduction, while maintaining the stability of the structure. The tracks are slided by four small linear actuators, driven by M motor. The mechanism of retracting tracks is based on guides of three studs height and one width. They come into the undercarrige, based on two cnostructions made of 5x7 frames, and connected by the system of sliding tracks. Details in photos below. The uppercarriage is mainly based on frames, connected by liftarms and housing made of technic panels. For rotation I used M motor with ratio 120:1. Three winches are made in similar way: the string is wound on a sleeve on an axle, between two 36 gears, driven by 12 gears. For lifting boom there is one L motor, and for moving the bucket there are two XL motors. I used modular counterweight, like in the real excavator. In the lightest configuartion it weighs 319 grams and consists of a battery box and back cover of the excavator. The heaviest configuartion of the counterweight it weighs 1140 grams. It consists of the lighter configuration and additional battery box, cover and lead weights (8x70g), which are protected against movement while driving the excavator. Boom is a simply, durable construction made with liftarms. Most angular connections are „legal”, but because of the narrowing of the first and the last section of boom, not all of them are. But they fits with no problem. Boom configuartions: I) I + IV: 30s + 44s, max height of the excavator 70 cm II) I + II + IV: 30s + 21s + 44s, max height of the excavator 87 cm III) I + II + IV: 30s + 42s + 44s, max height of the excavator 102 cm IV) I + II + III + IV: 30s + 21s + 42s + 44s, max height of the excavator 121 cm I built two buckets: a dragline bucket and a clamshell bucket. The excavator can be also used as a crane, but while lifting heavier element it would require bigger counterweight. Before I started the building, I wanted to make something fully modular. I think it worked out :) Operating the excavator is not easy, it requires a little of experience, which I am achieving. This type of machine is designed primarily to dig below the ground on which it stands (f.e. dredging water reservoirs), that’s why it’s hard to dig from a flat surface.

    Volvo H9X

    Volvo H9X Specification of the excavator Length 60s / width 31s / height 20s (47/24,5/16 cm) - without excavator arm Max dimensions of excavator arm: 60x35 cm(length x width) Weight: 3637 g Front suspension: none Rear suspension: none AWD Steered both axles Power - 2x 8878 BB 3x M 4xL 2x XL 3x Servo Specification of the trailer Length 55s / width 25s / height 17s (44/20/13,5 cm) Weight: 1398 g Power: 1x 8881 BB 1x XL Functions Driving - 2x XL Steering - M Gearbox - M Lifting the blade - M Excavator rotation - L Movement of the arm - 3L + 3 Servos Lifting the trailer's tipping bed - XL Today, I want to present wheeled excavator Volvo H9X with trailer. Model was built for Lego contest „Build the construction machines of the future”. Later it received many improvements… In short: it is wheeled excavator without operator’s cabin. I didn’t pattern the model on any real machine. As a scale I took Claas’s wheels. For driving there are two XL motors, which drive the 4 wheels, through two-speed gearbox. First gear ratio is 5:1, and second 1,8:1. The gears are changed by M motor and two 1x7 racks. Both axles are steered by M motor with gear ratio 3:1. In the front there are blade, driven by another M motor. In the upper part of the excavator there are three comperssors for three pnematic functions. First, which drives the four big pnematic cylinders, consists of L motor and two pnematic pumps. Next two compressors are the same (L motor + one pump) and they drive the pneumatic cylinders for moving second section of the arm and the bucket. The valves are steered by three Servos. For excavator rotation I used L motor with gear ratio 155:1. In the front there are double Led lights, powered by a switch. The trailer is a simple liftarm construction. The bed is tipped by one linear actuator driven by XL motor. It is powered by switch, because of lack of free channels on the IR receivers. Gallery

    Lancia Delta Integrale

    As said pagicence it allows easier drifting and more fun. Using differential also gives better steering angle. The difference in speed of wheel I tried to reduce by using 8878 BB for rear - with voltage 7,2V and gear ratio 1:3, and in front by using 8800 BB - 9V and gear ratio 1:2,15 With Lego powerfunction it isn't possible to do that, maybe with EV3, but I don't think so. Thanks for all nice words, using 3Ls for such small model gives really a lot of fun

    Lancia Delta Integrale

    Wow, it had to be cool experience to drive real Delta Integrale I_Igor is right, all clips are in original speed
  14. Lancia Delta Integrale Specification Scale 1:14 Length 37s / width 19s / height 13s (54/23,5/13,5 cm) Weight: 1050 g Front suspension: none Rear suspension: none AWD Functions Driving - 3L Steering - Servo Today, I want to present Lancia Delta Integrale. I’m sure that everyone know the original one, which won many rallies. There was few versions of Integrale: from norma road cars to monster with power of hundreds hp. This model is usual one. My main goal was to build small, fast car, which gives a lot of fun. The construction is quite simple. Lancia is driven by 3Ls - 2Ls for rear, powered by 8878 BB and IR receiver V2, and one L for front, powered by 8800 BB. For steering (with Ackermann geometry) I used servo.
