r/legotechnic

Tired of cars now, just saw this recently and I know I must get it.

Comes in small numbered packets.

Built using 927 parts from the original set.

Instructions available on Rebrickable: MOC-270258

Hope you like it

Recieved my Lego set from 1980. Bought it on a auction. Im so happy to have this masterpiece back in my life... Played with it so much when I was young. Designed a wall mount and this is the result !!

On top of the many people trying to fix the gear issue.

I just finish building my set and I have 2 extra black piece (2 extra on top of the extra piece list on brick link)

Check the car all around and found there are 2 missing spots that would fit these 2 pieces - but even the online manual doesn’t mean to have update/confirmed it.

What’s the odd that these 2 pieces indeed is for the space and the instruction missed it?

I recently saw this on instagram..but i can’t find this on their website…does anybody knows where to buy this…?😭

Rebuilt the mog again. I bought the set about a month ago, haven't used technic for 20 years but was always competent.

After building the model exactly to plan I got my box of spares from various education projects I used to run, plus a few new parts that I ordered. Initially I wanted to power the model using remote control. My first attempt was fairly conservative, changing the minimum of parts and shoehorning 4 motors in around all the other bits. I used power functions motors. The first attempt used the original m Motor for the PTO. I upgraded the compressor with a L motor and two piston pumps. The drive motor was an L mounted in the rear frame and, behind that, a servo for the steering. The PTO clutch was also pneumatically operated but I used a small cylinder and it wasn't really up to it, although it was compact. I also made the bed tip to the side but because the motors were in the rear frame i had a compromised cylinder location for the tipping body and wasn't happy. Additionally the L motor wasn't really up.to driving it.

So for the second rebuild I was much more ambitious. I completely dismantled the center section including the gear train and started again. I used an XL drive motor located low down in the rear chassis. I used a servo motor mounted centrally as a load bearing unit, hid an air tank in there, and rebuilt the compressor and pneumatic clutch with a big cylinder. This is less asetically pleasing but it works well and it's really satisfying when you move the pneumatic leaver and the clutch clicks.

This arrangement permitted the relocation of the remote receivers in the center area along with the ability to centrally mount the tipping cylinder in the rear chassis. (I lengthened the model by two studs to fit it in).

I made the cab tip pneumatically as well, which is super satisfying, the leaver is in the front left wheel arch. To fit the cylinder in for the cab tilt i had to move the engine back two studs.

I removed the hand of god steering as steering is now via the servo motor. However it always bugged me that the steering wheel didn't turn with the wheels so I fitted a gear linkage that joins the cab steering wheel to the servo motor. This automatically engages when the cab is lowered.

I also made the bonnet openable, and i needed to "bulk" it anyway to cover the linkage for the steering wheel and pneumatic cylinder for cab tilting.

Finally i ordered the spares for the snowplow attachment which is currently standard and unmodified.

I'm not 100% happy with a lot of it but after a couple of weeks work I need a break. In particular I was limited by experience, by the spares i had, and lack of initial plan - there was a lot of feature creep. So I think it could be built in a much more elegant way. In future I want to modify the snowplow attachment to include the winch, and make the rear stabilizer feet pneumatic.

Overall it's fantastic fun and I think this technic model set is just fantastic from a playability and modification point of view.

This was quite a challenging, but fun build.

While most steps were laid out as clearly as in modern sets, some mirror symmetric steps were not explained at all, only the needed parts and how it should look afterwards. But one step was just a few dozen parts added without listing them or explaining this all together. Figuring this out felt a bit daunting at first, but was doable with a systematic approach and a very rewarding experience. Now I know, why people praise the challenge of the older sets.

The handle on the left side moves the searchlight, the wheel in the middle both rotors (they are connected by an axle) and the right one opens or closes the rear for loading the car.

Some curiousities: This set has both studless and studded beams, really feels like a product of changing times.

Next I'll build the 42038.

I’m aware this is a niche within a niche so I’m not sure how or if anyone would be able to help me out here. This is my first time using BuWizz products and I just gotta say the UI is hella confusing and I’m not sure what I’m doing wrong at this point. As you can see when in the air and turning to the right the wheels don’t return to center and when going left they do, but when placed on the floor it’s the opposite. I did not build this set myself either so I’m unsure if it’s build issue or software issue, either or wouldn’t shock me. If anyone has any knowledge to share it would be greatly appreciated.

How different are the helmet builds from each other? I’m building Piastri’s right now, and it made me curious how much it varies compared to Hamilton’s, Leclerc’s, or the other drivers’ helmets.

Can anyone see a noticeable error on this amg gt3 build. I looked over everything and can’t find an issue but my front wheel arches flare out due to a spacer placed to protect the front light fixtures. I just can’t figure out how there’s such little gap in all the pictures I’ve seen.

Feels like I’ve been working on this beast for 1000 days. Happy to be done soon gap or no gap lol

Look to rebuild one of Lego's set with loose bricks. And notice this part is no longer available on pick a brick. I wonder what will be the best current alternative for it? Don't really need the hole on the panel..

Just saw this online 2 days ago. It's a 6 in 1 Pneumatic set which can be combined together into a larger set. Mainly target towards kids to let them explore how Pneumatic works.
