Hello all! It's been a while, I posted here anything, but now I'll try to upload my works more recently. I start with this Unimog 401, which is the oldest Unimog with Merecdes-Benz star. This one has also an "Ochsenkopf" (ox head) in the hood, which was later removed in the next generations. The building time took about 2 weeks at all, and this is my first model which got the special dark green color, to get close to the original's painting. I ordered several types of these bricks, more models will come in this color. I chosed for building the 1:7 scale, with the 108 mm RC4WD rock crusher XT wheels. They aren't Lego, but as far as I can see nowadays it's normal in tyres, and the look is better imho with these. Goals: Llooking and working authentically, as close as possible to the real thing, beside of off-road capabilities and remote control. Main functions: Motorized: driving, steering, gear change Automatic: steering wheel, piston engine, PTO in front and rear Manual functions: openable hood, doors, rear side Working: One Lego PF L motor drives, one M steers. The 2 speed linear gearbox is operated by a M motor. Steering wheel and suspension also works. The original has rigid axles with torque tubes, so I chosed also them. Four of 8466's springs were taken apart, so I got 4 coil springs to get the authentical look in machinery of axles. I also attached differential imitating disks. The rear view mirrors work a little. One L motor drives the whole thing, it's sliding in two axles, because of the 2 speed (1:3 and 1:1 ratios) linear gearbox. This way there is no need for driveshaft length adjuster between the driving motor, and the incoming axle of the gearbox, but the rear PTO has one from 6 holed pulleys. There is a PTO also in the front with a pulley, like in the original. The working L4 piston engine has mini pistons from 2L axles and half bushes. Details: I wanted to build as details as possible both inside and outside, like: detailed interior, steering wheel, stickers (for instruments too), gear change levers in the cab, handbrake lever, mudguards seen from inside, fuel tank, number plates, lights, seats, rear wood cover, detailed engine room, tanks for brake, exhaust, etc. Pictures I made it in the winter season, that's why you can see snow as background: https://www.flickr.c...157667176594155 http://www.brickshel...ry.cgi?f=563725 With dark green wheel covers: There are anti-roll bars to prevent rolling, the vertical 6L links connect them with the axles: The diff imitators: Of course I made a video, too: Hope you like it.
Hi! I made a few crawlers until now, and I wanted to create something new, with more fun. So I decided to add a lot of power in a lightweight chassis to be the crawler fast, but also capable. My goal was to make the most simple and effective Lego rock crawler: http://www.brickshel...ry.cgi?f=538615 I used a flexible frame as suspension, this helps to keep it lighter, there is no need for a lot of parts to create a 4 link or other suspension. As you can see below in the video, this "suspension" also works well on terrain. Has LiPo battery, and V2 IR receiver. There are two receivers, two XL motor is connected to each, there are 4 XL motors in total. After the motor's output, a 24:12 gearing (deceleration) is built in, so the wheel spins about 85 rpm, which allows to reach 1,7 km/h. The wheelbase-width ratio is similar to real RC crawlers. I tried to add a big ground clearance, there was no problem with it. It's an advantage of this flexible chassis, there is nothing under the middle of the vehicle. The wheels are RC4WD 1,9" Rock Crusher XT's, their weight helps a lot of the stabilization of the vehicle. The XL motors are placed low, they also help to have a better center of gravity. I added a simple body, with more crawler-like look, than in my previous crawlers. Steering: One M motor steers the two XL motors in the front axle. These motors are connected to mini turntables to be more stable and robust. The steering ratio is 5:1. http://www.brickshel...16_1280x960.jpg I used strong pins from 8842 to make stronger connections in the axles. All the motors and the main parts are connected together with these: Weight: 1105 g. I don't know yet the number of pieces, but it can be about 200.
