Two 42099 sets and about 1400 pcs used, 5 pounds and 21 inches in length. In total two technics hubs, 3 XL motors, 2 L motors. Everything controlled via BrickController2 and a Nintendo Pro controller, works extremely well. A very good crawler with lots of torque, it can go up and down sofas without little effort. Common 42099 mod performed where output gearing is switched around for more torque. Standard diff between all wheel pairs but the two rear axles purposefully without central diff, two XL motors drive the four rear wheels together for high torque. Very simple building instructions: Build one complete 42099, then build an extra front axle with steering and motor and attach in forward facing direction aft of rear axle. Quite a lot improvisation here but doable with time to play around. Technics hubs moved down and to the sides for better weight distribution, easy to change batteries without removing the hubs. If you want fixed drive between the two rearmost axles the easiest is to flip one differential inside one gearcase so it spins the opposite way, that way you can have a straight axle between two rearmost wheel pairs. With BrickController2 you can fine tune how much the rear axle steers in relation to the front axle, currently it's set to about 50%. Had lots of fun with this one and drives great!

What a shame they don't make them anymore. Anyone knows why?

Andrew Woodman said in a 2016 interview:

>It’s an emotional attachment for many people, a lot of the younger kids want to imagine a figure or driver in their model. When they get older they imagine it’s them in the model, so the figure doesn’t play such an important role. But for us the figure became came quite restrictive in terms of model scale and model size. Nowadays we prefer to create models that are the right scale for our building system, so while the figure definitely has some kind of story telling aspect for the younger kids, I think the figure has had its time…

I can't find a legit reason in here

Hello, I’ve noticed that there’s one part of my build that I notice is different, the red rod is sticking out more than it does in the manual. The other parts on the other side of it, the black L shaped piece is also not fully plugged in too. But the gears still all turn just fine so far. I’m just afraid that if I continue I’m going to have to take it apart anyways. Could someone tell me if I should continue building or just take it apart and fix it? The grey rod on the top of the L shaped piece might be too long I think and is making the red rod on the other side protrude. Any help is appreciated. You’ll be able to see in the picture the skin color piece is not fully in the black L shaped piece either. (But once again all the gears turn just fine)

I build a lot of random technic stuff (usually per my daughter's request). This time I was prototyping a cat tail that would move multiple joints in the same direction through a single mechanism. It didn't work out the way I wanted (it works, but the secondary joint moves very subtly, and there's no third joint), so I ended up making it into a scorpion instead. It has individual motors for the wheels, and one for the tail, and the last one for the hand grips. The small motor can't drive the grip well unless on fresh batteries, but on full charge the grip strength is enough to grab my finger and hold its own weight. Anyway this is a really fun RC toy. It's very challenging to steer though, especially when the goal is to pick up toys off the floor and move them around. It has a mouth space for eating random stuff too when it gets hungry. 😆

My second best suspension project

Do you guys like it? And don't mind the World Cup there lol

Hello !
I’m new to this Reddit, but I’ve been looking for where to ask that and fell down here

I’ve been doing legos for years now, and I’m of course used to the spare parts being the small ones

BUT
I recently bought the Technic 2022 Ford GT (42154) and through the build, on the end of the 4th bag, im left with some spares
But two that seems too big for usual spare parts, and in a pair.
I’ve been looking through the page over and over, did the build of that bag again, looked everywhere that part appears, and they’re all in their place

So is it normal to have these parts in a pair for spare ? Or did I miss something ?

Thank youuu
