Good day! I hadn't any inspiration for Pentax, so I decided to make a quick project. And here is the result, a mini car powered by RC buggy motor. With most of the bodywork removed: Dragged axle on rear.The RC motor works as a reinforcement for the rear axle. Double wishbone on front with return-to-center ONLY CHASSIS REAR AXLE Some progress photos on Tumblr I hope you like it, the video will come soon.

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. -
This is my first ever completed Technic MOC, originally inspired by Piterx' Lancia Fulvia but much simpler. It's not quite done, but I anticipate being able to spend very little time on Lego in the next year or two, so it's as finished as it's probably going to get. There is no gearbox or interior, and there are a number of things I'd change if I had the time - but overall I'm pretty pleased with it. The 037 was the last rear wheel drive rally car to win the WRC, in 1983. It raced in the infamous Group B category, which had few restrictions on vehicle design and engine power; as a result, the overpowered cars were in a number of fatal accidents, and ultimately Group B was abolished. While it lasted, though, Group B saw some spectacular driving and some extremely fast and loud cars. The Martini Racing stripes are done with washi tape (fancy Japanese colored masking tape), which works OK except where the tape crosses pin holes. It actually looks better in person than in photos. As in the original vehicle, the hood and rear lift up, and the doors open and more or less lock in place: Also like the original, the model is mid-engined. I used 1 RC motor geared 12:20 from the fast output. Until I put the bodywork on, the car could do handbrake turns and drift on wood floors, but now that the vehicle weighs 1030g, it can't drift and can only rarely do handbrake turns. I'm especially happy with the front axle, which includes a decent wheel lock, caster, unequal length wishbones, near-Ackerman steering, and a scrub radius of nearly zero. My thanks to all of those here who offered advice on suspension - I learned an enormous amount from you all. Steering is by servo, which offers return to center, reasonable speed, and high torque. I use a basic remote because the train remote is too slow for me to keep the car from crashing; the downside to that is that proportional steering is impossible. Wheel lock, steering, and scrub radius: Caster: The hub is held together by the 4L axle with stop (and the half bush on it), which turns out to be a more robust solution than I'd expected: The rear suspension is a modification of Thirdwigg's floating differential. It works well, with one caveat. Every once in a while, the 3L axle driving the 20t gear slips towards the differential a bit, and once when this happened a 3L u-joint got destroyed by torsion. The rear suspension is hard and has limited travel, and the suspension arms are tilted up even at rest; I would fix that if I had time. And of course the obligatory under-chassis shot: -
Hey everyone, quick question......My field has very little to do with anything in the technical sciences, that is perhaps why I love building with Technic so much... it gets me out of my realm of experience. But real quick, I have been interested in several older parts for a while, such as the RC buggy motor, micromotor, motors for the 9v system, and others. I was in my dark ages during these times so I have none of these, but I have no problem buying some --- even if they are costly. I just think that it would be fun to try some builds with such parts. However, my question is regarding part degradation over time. Is this something that I should be concerned about. I mean, some of these parts are nearing 10-15 years old. I understand aging brick..... but electrical components are a little more finicky. I know many still use them with success, so I am not really looking for answers such as "I still use them with no problem" - more like someone with in-depth knowledge of how such materials behavior through time or stand up to time. Again, it is not as though I previously bought them and have gotten use out of them for years. I would be barely acquire them, so unless I can expect a long life, as fun as it sounds to get them perhaps I should pass. Anyone with some in depth knowledge or experience on the matter?
