I meant something like this: The cabin would work perfectly there.

42030 because of the huge amount and variety of PF parts.

Looks very good so far and I like the unique cab style. You could probably build an american style fire truck with that. Now you just need to make it fully remote controlled

Very cool. Gonna build it when I have some time. Thanks.

True. I guess one could use those foam fillers from regular RC tyres. Would probably help a lot. I think this would generally be good to use anyway on soft tyres.

Is it again based on your 5 axle 8258?

That is because the tyre bends in the middle section where it sits flat. That comes because of the soft rubber.

Watching YouTube videos through a proxy sucks somehow ;)

I'd say, make the body lighter. Or add more wheels to compensate for additional weight.

Common advice: Don't use friction pins on moving parts like this.

You probably have to think about functional steering first

Nice review. That made me laugh. And by the way, you mounted some of the rotor blades the wrong way.

These new tyres might also be useful to build a old-school muscle car. You know, like those muscle cars with the balloony rear tyres. Like this Dodge Charger:

I thought about that, too. But today I had a different idea for the crab. Looks promising for now. Perhaps I need to rework it once more. Basically the frame of 2x4 bent liftarms lies on the upper side of the rail and the 2x1 liftarm with axlehole provide some stability on the lower side. It is run by a 16T gear. The new red 8T slider gear has no function. It is just there, so the worm gear does not slide back and forth. Here is another view: Next step is to get this properly driven and the 32L axle attached to the boom. Here is the .lxf Suggestions are welcome.

Hi fellow addicts. A word beforehand, if I call the mechanism wrong, please correct me. I am currently still developing some kind of hooklift container truck as a C-model of 42009. This is more challenging than I thought. At first I had the idea of building a hooklift mechanism as it is common on trucks. But what I came up with was either too unstable or too bulky. So I was thinking about this a lot, then laid it aside for a while. Now I am back at it and have a new idea. I saw some other container trucks, the work with a simple hoist mechanism, but that seems somewhat inapropriate and I will only consider this as last resort. And then I came up with a idea of some kind of a boom that can extend. My idea was, that the "platform" can extend by half and the "hook" travels the hole length so the tipped platform can take on the containers. Still super complicated and probably impossible with the given parts. Now I have this boom idea tha is basically a boom like on the crane, but instead of extending, I have a crab going the whole length. Containers will be put off and on through tilting the boom and the traveling crab. I have a prototype, but before continuing, I wanted to ask if someone has a brilliant idea to make the crab more stable or rigid. As it is now, it will probably fail under load. Here is a picture of the boom center: The boom itself will be wider later to provide good travel for the container and to secure the crab to the sides. And here is the prototype crab: The wheels roll on the side liftarms of the boom. The 32L axle drives the wormgear, which then lets the crab travel via the gear racks of the boom. I would have shown this combined, but LDD wouldn't let me. The question is: How can I improve the crab to be more stable? Also there is a height difference. So if the 32L axle would rest in the black 3L pin with center pinhole, that would be awesome. I know the height difference could be solved by driving a 8T gear through the worm gear which sits on the same axle with a 12T double bevel gear which drives the gear racks. Getting the 32L axle to the same level as the pinholes of the boom would be brilliant. Also, here is the LDD file! Thanks in advance for all the help!

We have such pre-paid credit cards here in germany, but it's just like a regular CC. Only difference: You need to fill it before using instead of paying at the end of the month. Still the same hassle as a regular card.

In cases like this, I wish I had a credit card so I could back the project

I only have the MB Trac as lxf in my Brickshelf. The Dropbox Link for the 8110 Iveco Model should work again. You were lucky I checked this thread ;)

That's why I said theoretically. I know that the plain physical factors are restricting this a lot. Still, this would all be very interesting. Isn't there someone with way too much money who can try this?

That is really really cool. And a great idea. Well done I wonder how high you could theoretically build before the batteries die

Sweet. I also find it impressive how much you pack into such "small" scale

I usually build all B models. And this particular one was really fun. I even dare to say, it is more interesting then the crane - in regards to mechanisms. And even if it doesn't look to good, it works pretty well.

When I got the 9396 I also built the B model after a while and had in display for quite some time. I really liked it because of the intermeshing blades and all. I think I will rebuild one of the two models soon.

Answer to both: I did mean the 9398 wheels. But, in the video he just held them next to the pickup for comparison. I just wondered what the Pickup looks like with these wheels mounted on it. But, in the meantime I saw the comparison picture of rm8 ;)

I think, automatic backup works a lot better in cases like this. Things you have to start manually tend to be forgotten, in which case no backup usually is near as good as manual backup.
