[MOC]- Soviet Tracked Vehicle BWSM 80
Samolot posted a topic in LEGO Technic, Model Team and Scale Modeling
BWSM 80 was a prototype of a "sanitary" vehicle created by combining the DT 75 bulldozer with a GAZ 53 cab. I've found its picture in the RU-net already a few years ago, but it waited for its turn in a folder with inspirations. It used to be orange Porsche that I could build Zila 130 now from blue Bugatti I made Gaz 53. I wonder if a new secular tradition was created? Three weeks of holiday in the countryside was enough to build this 60 cm model. There were several challenges in the construction. Weight, the model could not be too heavy because it had to rise and ride on tracks. It determined the entire construction. I could not use too many PFs, a complicated suspension, fake engine under the hood and details of the interior. The biggest challenge arose, how to use the two PF-L to master the drive in three variants. 1 Only wheels 2 Only caterpillars 3 Wheels and tracks simultaneously For a good balance, the motors and Battery Pack are at the end of the vehicle. In front of the PF L motors there is a system of three gear boxes, two of them transferring the drive from the PF l motors directly to the caterpillars or to the rear wheels (one motor ) and the front axle turning (the second motor). The right motor, however, is attached to the second gearbox in front of the drive wheels of the caterpillars. With it, you can drive the right caterpillar "from the front" simultaneously with the wheels. To drive left caterpillar you need, the fourth box which is placed at a 90-degree angle to the others and uses a blue 2o zgear from Bugatti. It is just transferring power from the right engine to the left caterpillar. A completely different challenge was to make this 2.5 kilogram move efficiently on relatively short caterpillars. Obtaining the right stiffness required a lot of mass tests. The model lifts up a single PF M handle thanks to a double worm gear with toothed wheels with z 40 and two clutch z 24. Another difficulty was the fact that when lifting, you have to compensate with the tensioning wheel changing the caterpillar tension. I got the desired effect thanks to the system which, when moving the main lifting arm by 9 studs, shifts the drive wheel axis by only 5 studs. In addition, the tension is supported by four small shock absorbers. To make the vehicle lightweight I decided to simplify the suspension and the use of leaf springs, there are also no extras such as the fake engine under the hood or the detailed interior of the cabin. I only added lights in the front. I hope you like it and I look forward to your comments.

This diorama shows three different scenes from the movie Saving Private Ryan. All the action is taking place on Ramelle bridge at the same time (just for the purpose of this diorama), although in the movie there was a longer time frame between these scenes. The first scene is in the middle section, when Captain Miller on the bridge shoots with his Colt into Tiger I tank, just a second before P-51 destroys the tank. The second one is right after Tiger I explodes and German soldiers starts to run. Corporal Upham captures a small group of soldiers. Among the captured soldiers, Corporal Upham recognizes one German soldier who was captured and let go previously. The third sequence shows the arrival of the allies.

So after a rather poor start I decided to totally reimagine and rebuild the Mercedes truck of the future. It all started with a random idea of routing 4 functions through a turntable like this: After fiddling around in LDD for few hours I came up with an 8 function gearbox powered by a single RC motor: The functions shown are: Orange - RC motor drive Lime - Horizontal extending od outriggers Yellow - Vertical extending of outriggerd Violet - Slide and tip of the bed White - Rotation of main arm superstructure Light gray- Rotation of claws Red - Lift of main arm Warm gold - Movement of claws Dark gray - Rotation of scondary arm After this rather unusual design process it was time to think of the basic shape of the model. I was inspired by the 42038 arctic truck's layout, but I wanted to add my own twist to the formula... Here's the result: Here you can see the massive cran arm used to pick up various loads: The truck uses four of the biggest Lego wheels in front and 4 tracks in the rear: As you can see all tracks and wheels have fully functional spring (and additional pendular for the tracks) suspension. Also notice the massive bed tipping angle. The truck also has a fake V8 piston engine driven by the tracks: And a prestige sand-colored interrior: Steering is done via HOG and the spare tyre behind the cab: Here's the description of the concept idea: _________________________________________________________________________________________________________________________________________________________________________________________________ This is my model for the future 2045 Mercedes-Benz competition. I named it Antos and it has several features: The engine is Euro 11 compliant 6-stroke aqua-diesel-electric hybrid. The additional 2 strokes inject water into the hot engine with expands as steam adding another work cycle. The engine also powers an electrical generator which is used to power the truck's front wheels. Front wheels also act as a generator while braking, therebye returning the electrical power back to the batteries. Tracks are driven directly by the diesel engine. For optimal performance the front is equiped with many air surfaces which reduce drag. Because this is an offroad truck, the massive wheels and 4 tracks in the rear provide it with massive traction area, which reduces ground pressure and preserves ground vegetation. The multi-functional arm and bed are driven by a single motor using a mechanical multiplexer mechanism. The Lego modes uses solid axle suspension in front, suspension on all 4 rear tracks, a fake V8 piston engine driven by rear tracks A powerfull RC motor powers the 8 functions. I managed to reute 4 functions through the turntable in order to fully motorize all arm functions. Total number of gears used for arm and bed (not including steering and fake engine gears)is over 130 making this one of my most complex switchboxes to date. The front was slightly inspired by the Unimog 400's sloped cab, but with added wings and a lower bumper. The idea for the tracks and arm actually came from the 2014 Lego technic arctic vehicle. The rear bumper is in a shape of a V in order to allow the bed to slide out and tilt. Interrior is detailed with seats, steering wheel and handles in prestige sand color. __________________________________________________________________________________________________________________________________________________________________________________________________ And as usual here's a short 3 minute video. (3 minutes is max time so you may pause some text) I hope you guys like the truck, I personaly think its a very retro-futuristic beefed up advanced half-track concept and in that sense something different and original.

[TC7] Bandits - The Sandstormer
MajklSpajkl posted a topic in LEGO Technic, Model Team and Scale Modeling
Greetings fellow combatants! I would like to introduce you one mean notorious bandit: The Sandstormer! As you can see, it's a half-track, roaring over the dried salt-lakes plains, camouflaged into a supplies transporter, but when the heat turns up, it transforms into... ...flying assault bomber called "The Storm"... ...and remotely controlled tracked ground unit called "Sand Wrath", which is guided by the co-pilot on the bomber. PLOT Bandits! Fear not, air support is here! We shall stand victorious and no enforcer will ever be safe in the Desert!!! But first let's take a closer look on this monstrosity, forged in the heart of the Desert by some crooked eyes mechanic called Furious Majkl. If you'd known him, you wouldn't be surprised that some things didn't came out just as they should, but this poor fella couldn't do any better on such a short notice and with a gun on his head. The Dusty Lord of the Desert was ruthless, as the day of the final battle with the Enforcers was aproaching with a speed of the sandstorm... The necessity for an airborne unit among Bandits was great and what is more devastating than a heavy bomber, carrying deadly cargo. In order to keep it secret, the idea was, that the combat vessel turns airborne from a somewhat common desert vehicle whit big enough sides to turn into wings - logical choice: A truck. Next, the choise of on ground propulsion system - treads, can there be anything more universal? A half-track! Lets take a look at the specs: NORMAL MODE - HALF-TRACK ("The Sandstormer") Dimensions: L/W/H = 54 cm / 20,5 cm / 20,5 cm (67,5 / 25,5 / 25,5 studs) Weight: 3,2 kg Main features: Drive (tracks - 1x PF L motor each = 2 all together) & steering (1x PF L motor) Battle options: Two double huge miniguns on front + 2 double barrel machine guns behind the front bumper when lowered + Infantry reaper on front bumper when lowered. BATTLE MODE - FLYING ASSAULT BOMBER ("The Storm") + REMOTELY CONTROLLED GROUND UNIT ("Sand Wrath") The Storm: L/W/H = 66 cm / 78 cm (wingspan) / 17,5 cm (once airborne) (82,5 /97,5 / 22 studs) Weight: 2,3 kg Power: Nuclear AAA BB core (+good ol' kerosene of course) Transformation: 1. The sides rise up and turn into wings - 1x PF M motor drives 2 large LA's that firstly push the whole panels sideways and then they rise them into horizontal position. 2. Risen wings rotate into final position and the tail extends - 1x PF M motor (suffering as hell due friction, but there is just no space for anything bigger) 3. Tail wings and middle wings are put into final position manually (tail wings by a worm gear) 4. The Storm and the Sand Wrath separate: Two "claws" operated by small pneumatic cylinders driven by an auto pump (1x PF M motor) release the ground unit so it is set free. The rear landing gear is of-course already in position for take-off (1x PF M-motor drives two large LA's) 5. Once the Storm is airborne, the front two wheels are turned downwards (1x PF L motor) so that the wheels turn into extra thrusters for faster rising. 6. Armaments: As the wings unfold, they are already weapons-hot, carrying triple rocket launchers on each wing and a double laser gun on each side near the hull. In addition the front hood can be risen and two huge miniguns pop-out, escourted by two double machine guns when the front bumper is lowered. Total mayhem is achieved by a hydrogen drop bomb, which is carried inbetween the front wheels, which turn upwards to deploy the deadly cargo... As already said, the constructor - Furious Majkl was in a hurry, therefore the fuel lines for the thrusters on the main wings is supplied via "external" hoses, which makes it somehow vulnerable, but it is a minor problem due to huge fire power not letting anyone near those "blood" vessels. The Sand Wrath: L/W/H = 24,5 cm / 20,5 cm / 20 cm (with mini gun in top position) (31 / 25,5 / 25 studs) Weight: 0,9 kg Power: Nuclear AAA BB core (and some good ol' diesel) Drive: 2x PF L motor, 1 for each track Transformation: Once detached from the main unit, it goes berserk and due to each track being pendulary suspended, there is no obstacle it cannot overcome (well almost, due to lack of road wheels sometimes overcoming obstacles in reverse is a problem ) But still, it is a lot of fun to drive it remotely from far above on the Storm - yes, the Sand Wrath holds no crew, just deadly weapons... Armaments: The connection platform with the Storm turns into a huge minigun and underneath it there are two deadly long range cannons. For close combats, pursuits and drive-bys it reveals additional double machineguns on the sides of the tracks. That would be all the glorry for this war machine, you can check some details/mess from following photos of the guts below... Pneumatic autovalve... And now to conclude this epic poetry with the ugly truth about this model: There is still a ton of things to improve: I, well Furious Majkl of the Desert seems to have a leaking small pneumatic cylinder and that results in a rather poor functioning of the detaching claws betwen the two units. Perhapse the small pump just cannot provide enough presure - I've tried with big manual pump and it work like a charm. To me, this detail is the biggest fail of the whole MOC. You can realise, that remotely reataching both units back together is even worse . Oh well, it's only LEGO they say, you can't achieve it all, they say... Seems they're right though. Anyway, this attachement detail should be reworked totaly. Another rather "notsoamazing" thing is driving the normal mode vehicle. Slipping tracks are the least of the problems. What remains is steering of course. Due to rotating design of the wheels around the longitudinal axis the front is rather flimsy - you all know how little bending the turntables can take. Well, since this baby is one heavy child, I had to use stroller wheels on the bottom of the belly, so it can steer and drive at least a little... Nevertheless, I hope you like this lovely "pile" of bricks that me, myself and Furious Majkl of the Desert put together Best regards and good look to all you feisty petrol-head warriors! Make sure to vote for your favourite contestant, because those without a voting ticket will be left in the Desert! I must thank my friend Peter for letting me use his camera and studio and for helping me a bit with the setup , I couldn't have done it in my tiny LEGO room ! Here's another to go... ...and finally - the video! -
Hello Everyone! Been a while since I posted a 'complete' MOC (Tries to keep a straight face) I present to you McLeach's Truck! This has been a long time in the making and a very very frustrating build. Originally this was going to be my entry into the TC6, but just ran out of time due to too many problems. This truck is from the movie The Rescuers DownUnder, A great movie if you haven't seen it. The first movie to feature cutting edge 3d animation of the time and still looks not too bad today. The movie bombed at the box office due to being released along side Home Alone.... This MOC features drive using 2x L Motors, and steering using a servo. The crane with in the movie fires net rockets and can be used to lift stuff with a hook, is powered by 2 M Motors. As I said this was a terrible build and tho looks good, doesn't function too well. Copying the movie truck its clear the animators didn't really concentrate of actual mechanics. haha. The truck in the movie gives new definition to the term "floating axle" Never the less I did my best to copy it. More pics here. https://flic.kr/s/aHskbQkgQh

Hi everyone! Having been inspired by Matthias Riedel's Blacktron MOCs, I've been making some builds using the same colour scheme. Namely Black, Dark Bley and Trans Neon Green, which is inspired by the Rench minifig from Raid VPR (5981-1) and the Space Villain minifig (8803-6). I want to say in advance that I was very unhappy with my photography. Sorry about that! Some Notes! - The halftrack is originally by Matthias Riedel: http://www.flickr.com/photos/mr_blacktron/ - The crawler is based on a Nova Crawler, which is an alternate build of the Exo-Force kit, Supernova (7712), inspired by Matthias Riedel's blacktron MOC of same: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=412775 - The racer is a recolour of the Agents kit, Infearno Interception (70162). - The walker is an updated Sub Orbital Guardian (6878-1) from Blacktron II. - The fighter is a recolour of the Ice Planet 2002 set Blizzard Baron (6879). - The submersible is a MOC with it's main design forms coming from the Aquazone set, Crystal Scavenger (2160-1). Many more pics in my Flickr album: I've also ordered components for 8 more Neo Blacktron minifigs, and am eagerly anticipating their arrival! Comments welcome!

Hey Everyone! Here is my entry so far. (WIP) Pics 2 posts down. I haven't been too well, and this weekend was the first time I built in 5 weeks so I am very behind with this project. https://www.flickr.c...th/16349961667/ Not sure if I will get it done, if someone could give me an hour countdown Euro time, that would be great! Cheers.

[MOC] Sd.Kfz. 9 18t Famo 1/15 (RC) halftrack
Tommy Styrvoky posted a topic in LEGO Technic, Model Team and Scale Modeling
Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr This is my first halftrack, and it turned out pretty well. The Sd.Kfz (Sonderkraftfahrzeug) stands for special purpose vehicle, this vehicle is the largest halftrack that was produced in large quantities during World War II. It was used to haul heavy gun emplacements like the 15cm, 17cm, 21cm, and 24cm ; it was also used to tow damaged vehicles, one Sd.kfz 9 could pull 28 tons of weight. This allowed one vehicle to easily pull a Pz. IV and lighter variants but for larger tanks like the tiger and panther series, it would require 3 of these to pull one of them. My model is powered by 2 XL motors that drive a 1:3 ratio then a 12:20 for the final drive ratio .The chassis is composed of studless parts so its a very rigid construct, on top of that is a studded cab and bed assembly. There are 3 M motors (winch, engine, steering). Features of my model -torsion bar suspension for interleaved road wheels -front axle is a live axle suspension -utilizes a braked differential for ease of turning long tracks -headlights -continuously idling V6 engine -steering wheel rotates when steered -motorized winch -folding windshield -easy removal of battery box Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr the steering box and the braked differential, the rear rack and pinion applies pressure on one of the 2 disk brakes Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr Lego Sd.Kfz. 9 18t Famo 1/15 (RC) by Tommy Styrvoky, on Flickr this is how strong the chassis is ( it weighs approximately 10 lb's) Lego Sd.Kfz. 9 Famo 18t 1/15 (RC) by Tommy Styrvoky, on Flickr -
I was just playing around with some parts when I decided I wanted to make a M3 halftrack (which, btw is something I have wanted to do for ages). During the built I also decided to make it all purist, so here you have it, pretty neat design, and completely purist, I even made a brick-built browning, just like the good´Ol days ;-) Lego M3 Halftrack [MOC] by =DoNe=, on Flickr Oh and before I forget, more pictures can be found on my MOCpage: http://mocpages.com/moc.php/370183
