    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
  4. 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.

    Porsche Carrera GT

    Thanks for all the nice words :D Thanks, here are some :) Actually, I didn't notice it :/ Not now, but maybe in some time.
  6. Porsche Carrera GT Specifications Scale 1:8,5 Length 67s / width 29s / height 17s (54/23,5/13,5 cm) Weight: 2500 g Front suspension: independent pushrod Rear Suspension: independent multilink pushrod RWD Functions Driving - 2L Steering - Servo Moving spoiler - M LED headlights Working steering wheel V10 dummy Openable doors, hood, trunk Removable roof – like the original After a longer break I would like to present the Porsche Carrera GT. In my opinion it’s the best Porsche ever made. My nick commits, so I decided to build it ;) Original car was produced in 2004-2007, had V10 engine with power 612KM and the maximum speed at 330km/h. The construction isn’t very complicated. Porsche is driven by 2L motors with ratio 1,4. It eliminates resistance, which would be in the gearbox. Thanks to that the car is quite fast. My first decision was to place the Battery Box in the middle of the model for easy battery replacement. That’s why I had to build the frame a bit different, because in the place where usually were liftarms, now is Battery Box. The spoiler is moved by 2 mini linear actuators driven by M motor. The front and rear suspension is similar to the original one: independent pushrod. It works same as in F1 cars. In front there is also Ackerman geometry. For depreciation I used 2 springs from yellow 6.5L absorbers (in front) and 2 yellow absorbers 6.5L per wheel (in rear). Suspension would have worked a bit better, but it’s imitated by the original, and in the real Porsche all the links are form metal, here are plastic. The steering is really simple – servo, gear 12 and gear rack. I’m generally satisfied with the model, it looks and drives quite good, but the suspension would have worked a bit better ;) Pictures – of course with comparison to 42056 Gallery

    Solaris Urbino 12 IV

    Thanks for nice words :) I didn't use hub parts, beacuse they don't affect on the sagging. They also cause that the rear axle is wider.
  8. Welcome, I'd like to present a bus Solaris Urbino 12 IV. Specifications Scale 1:15 Length 103s / width 23s / height 27s (83/18/22 cm) Weight: 5,4 kg Front suspension: Independent, double-wishbone Rear suspension: Live axle Suspension with kneeling system RWD 2-speed gearbox AA+AAA Battery Boxes 7 motors Functions Driving - 2XLs Steering - L Opening doors - M Kneeling system - L + Servo Changing gears - M LED headlights Working steering wheel History Some time ago I decided to build a bus. I chose Solaris, beacuse it's a polish concern, which is producing buses and trams. I started building in mid-Febraury, and I finished it few days ago. Chassis The biggest challenge was to construct a strong chassis. We need to remember that it's a low-floor bus. The drive motors and the gearbox are (like the real one) located veritically on the left, behind the rear axle. It's causing big stress and I had to overcome it by the chassis. It consist of 3 parts: at the bottom there is a floor 2s thick, built from panels 5x11 and frames; at the top there are beams 3x3s on each side of the bus, they are built from liftarms. These two elements are combined by 7 rungs. The construction of the chassis is similar to the hulls of ships and planes. Drivetrain The bus is driven by 2 XLs. Gearbox ratio: I - 12,6:1 II - 4,2:1 The gearbox is built from frames, using 2 gear 24, 1 gear 12 and 1 gear 36. The gears are changed by M motor and mini linear actuator. The biggest problem was to lead the drive from gearbox to the axle. It is the weakest point of the bus - 2 universal joints, connected to the gearbox and to the axle, under a load break. Steering For steering I used L motor with reduction 14,4:1. It propels the gear rack 1x13 and also the steering wheel. Suspension Front suspension is independent with 2 yellow 6.5L absorbers per wheel. Rear is live axle. It has 1 grey and 5 yellow 6.5L absorbers (1 grey and 2 yellow for the right side and 3 yellow for the left side). Opening doors + kneeling system The doors are opened by M motor, reducted by 40:1. The drive is transmitted by liftarms used as links. The kneeling system is realised by 2 medium pneumatic cylinders. The pneumatic wires are connected only from one side, so the bus can rise using the absorbers. L motor drives the compressor and servo opens the valve with reduction 3:1. These 3 motors are electrically coupled, so in each door there is a gear with clucth. Thanks to that, the compressor doesn't stop at any time.

    Mitsubishi Lancer Evo X 1:8

    No, it doesn't. It's all my idea :) Yes, there is a little friction, but it doesn't influence on driving and doesn't pop out. And yes, it looks like that, because of McPherson. I know about that, but the center pillar is based on that part. If I were to make the roof shorter, I should use these pieces,but when I saw it's price, I decided not to buy it :D Thanks for nice words :)
  11. Welcome everybody :) Today I’d like to present my new MOC. Mitsubishi Lancer Evo X Specifications Scale 1:8 Length 74s / width 31s / height 21,5s (60/24,5/17 cm) Weight: 3700 g Front suspension: McPherson struts with realistic geometry – Caster, Camber and Ackerman Rear suspension: independent, multilink 4x4 drive 4-speed gearbox AA + AAA Battery Box 6 motors Functions Driving (2 XL + L) Steering (L) Changing gears (M) Locking central diffrential (M) Led headlights (switch) Working steering wheel Opened bonnet Opened trunk Opened doors (front with lock) History From a long time I wanted to build Lancer Evo. When I saw Impreza WRX STi built by Pipasseyoyo, I knew that I have to make his “eternal rival” – Evo. What’s more I prefer Lancer than Impreza :) I started building at the end of the May. It went quite fast and after one week the chassis was done. Unfortunately I created the body not as fast, because I finished it few days ago. Drivetrain The Mitsubishi is driven by two XLs and one L motor. The XLs are connected with the gearbox. It uses the new driving rings. Then from the other side the drive from gearbox goes to the differential, and from the second one an axle from L motor with reduction 3:1. The differential powers the central differential, which transmits the power to the axles. It is a bit complicated, so there are some diagrams :) Gearbox ratio: I 5:1 II 3:1 III 1,67:1 IV 1:1 The changing gears mechanism is based on that presented by Sariel few months ago. It is powered by M motor. For locking the differential I used M Motor with reduction 3:1. Steering For steering I used L motor, which propel the gear rack 1x13 with ratio 9,6:1. Suspension In the front there are McPherson struts. I tried to imitate them correctly, tahat’s why there is a geometry – Caster, Camber and Ackerman. For depreciation I used 9.5L absorber (from Unimog) and grey 6.5L. In the rear there is multilink independent suspension. I used 9.5L absorber (from Unimog) and yellow 6.5L. Some photos Gallery

    Fiat 126p 1:8

    Welcome everybody :) Today I’d like to present my new MOC, which was built especially for a contest on LugPol. Fiat 126p Specifications Scale 1:8 Length 51s / width 23s / height 19s (41/18/15 cm) Weight: 2040 g Independent suspension Rear wheel drive RWD 4-speed sequential gearbox AAA Battery Box 88880 Functions Driving (RC) Steering (Servo) Changing gears (L) Front LED lights (switch) R2 dummy Working steering wheel Opened bonnet and trunk Opened doors with lock History I started the building of the model at the beginning of the December, to the Christmas I built chassis, later I created the body. Because of creating the Fiat, I canceled my previous project – Mercedes SLS, becuse it wouldn't fit in the rules of the competition. If you don't know, how the original car looks like, here are the pictures. Drivetrain Fiat is driven by single RC motor. The gearbox is based on Sheepo's one from Veyron. Gearbox ratio: I 5:1 II 3:1 III 1,67:1 IV 1:1 To change gears I used 1 L motor. The ratio is 8:1 (worm gear). Fiat is a bit slow, because at the beginning I didn't want to exceed 1,5 kg of weight, and I hadn't got enough time to improve gear ratio or use 2 Xls. Steering For steering I used servo motor, which propel the gear rack 1x7 with ratio 1,67:1. Suspension The front and rear suspension is independent. I tried to make the rear like the real one, what you can see in the picture. Some photos Gallery

    Porsche 918 Spyder 1:10

    Thanks for the suggestion, I will use it in my next MOCs. Actually, I didn't know about it :) No, I haven't. The differential is located in the frame 5x7 and there are two bevel gears in both sides of the differential. Thank you all for your nice words :)
  14. Welcome everybody :) Today I’d like to present my new MOC, which was built especially for a contest on LugPol. Porsche 918 Spyder Specifications: Scale 1:10 Length 58s / width 27s / height 13s (46,4/21,6/10,4 cm) Weight: 1800 g Independent suspension 4 steered wheels 4 wheel drive Functions: Driving (RC) Steering (Servo) Tilting spoiler during turning V8 dummy LED headlights Openable mask, bonnet and doors History I started the building of the model 2 weeks ago. In the first week I created the chassis and in the second week the body. The main goal was to build a sports car driven by RC motor with four wheel drive. I was watching different car models, I wanted to build a Lamborghini, but at the Brickshelf there are lots of them. So I decided to build Porsche 918 Spyder, which, similarly as new 911, has 4 wheel steered. The contest assumed that you can use only 2 motors. So to the maximum use of motors I decided to built a spoiler which works like the Pagani Huayra’s one – during turning one side of the spoiler goes up, e.g. the car turn left and the left side of spoiler goes up. Driving Porsche is driven by single RC motor from the slower output with ratio 5,5:1. There are driven four wheels using three diffrentials. Steering To steer I used servo motor. There are two steered axles: the first with ratio 1:1 and second with 2,8:1. To the axle responsible for steering of the rear wheels there is a connection to the spoiler which goes up during turning. Suspension The independent suspension is based on the Lego arms. On each front wheel there is one spring from the yellow absorber 6,5L and a rubber band connected to the arms. In the rear wheels for depreciation there is used one yellow absorber 6,5L for each wheel. Some photos Gallery
