    On my list is the LVS truck that the U.S. Marines use. It doesn't have a huge amount of functions, but I find the modular characteristics of the truck interesting. Odd steering too. The MMRS that dr_spock posted is one of the projects I'm working on at the moment.

    I really like your Mack Granite. I drove a tandem axle day cab Mack and a Volvo sleeper, and I've got a soft spot for the Macks. You've nailed the look of the Granite.

    This is great! Getting the weight in just the right spot must have been a challenge. It's funny that you posted this too, because I was contemplating an attempt to build the rollgolf.

    This is really great! The bounce mechanism is ingineous, and I really like how you are able to move the rear axle forward to control the height of the bounce. Getting the center of gravity just right for this must of been tricky. Well done! Great camera work too, and I particularly like the shot in the water.

    I hate to be a party-pooper, but there is no way a 7' long plane is going to take off with Lego RC motors. Probably won't even have enough thrust to roll forward. Good luck with the project!

    Dassault makes some amazing jets! If I ever buy a jet, a 7x or 8x would be it (or maybe a Pilatus PC-24). As far as your 5x goes, I think minifigure scale is too small. My vote is something large enough that will allow a full set of moving flight controls and retractable landing gear. Are you planning a brick built plane, or something built using Technic panels? Not sure if this will be helpful, but here is a thread about the Super Cub I built: http://www.eurobricks.com/forum/index.php?showtopic=68476 It's great to see the possibility of another aircraft moc being built!

    Welcome to the forum! Before I start the build process, I usually make a list of the function and motors I want to use. Sometimes, I make sketches to figure out the motor placement and overall layout of things. If I have more than eight functions, I list which functions to group together in a gearbox. Once I start to build, I usually start with the most difficult section(s). If I'm building a large moc, I usually bounce back and forth between difficult sections. I find that if I can't figure something out, setting it aside and coming back later usually gives me some new ideas. If I were building a truck, I would probably start at the axles/suspension, then chassis and drive motor placement, then whatever special functions it has, then the cab design. As for building tecniques, building a few sets will give an idea how pieces and gears fit together. I usually start at the base of my moc and work up, although when building with studless parts, I do have to think about the vertical structure as well. I hope that helps.

    I think a beam should be added on the bottom and the proper 12t gear used. That's the only way LEGO would configure this.

    Great topic! I build a camera vehicle to film my Super Cub, and they are great for interesting shots. The one I built was no where near as nice as this one though.
  10. dhc6twinotter
    That's awesome! Really wish I could have made it Brick Magic this year. It would have been great to see you all and your mocs.
  11. dhc6twinotter
    Only thing I can think of would be long gear racks, particularly when used in boom extensions. Connecting a long row of 1x4 racks together on 1x16 bricks is easier than studless beams.

    The new Ferris wheel set has a few.

    Lego has finally made 6x6 yellow dishes! Woohoo! These should look good inside black or yellow rims. I've been wishing for these a long time.
  14. dhc6twinotter
    I ordered the PS and PC about a month ago, and I just received a message saying they had shipped. Woohoo!
  15. dhc6twinotter
    The flex system.

    If you can afford both 42009 and 42030, you will have an excellent assortment of parts to start with. You could build all sorts of awesome things, so long as it's yellow.

    The most common method seems to be a mechanical gearbox, but there are other options as well. There was a thread a while back that went off topic (partly my fault) where we ended up talking about various ways to multiply functions. We discussed gearboxes, like what is in 8043; banks of PF switches, like saberwing mentioned above; and using banks of pneumatic valves, similar to what I'm using in my current project (I'll post a WIP soon).

    All the large trucks and buses I've driven had the steering link (drag link) connected to the left knuckle, but I haven't studied truck steering enough to know how common this setup is. I do know the Freightliner Cascadia had an optional rack and pinion steering package, but it was problematic, and I'm not sure if it is still available. Volvo and Prevost have optional IFS on their buses, and probably other manufacturers as well. The Chevrolet minibus I used to drive had IFS and rack and pinion steering. Connecting the draglink to the tie rod was pretty common in older vehicles. The Toyota 4Runner I used to own had this setup. That all being said, I don't expect Lego to build a realistic suspension for the sets they offer, especially when they have to take into account scale and durability. Just the fact that they have suspension on 42043 is impressive, and I find their rear axle setup quite ingenious, even if the links have a small amount of sideways stress. Building a dual drive tandem axle with a fully articulated suspension is not that easy, and I think Lego has done a pretty good job, all things considered.
  19. dhc6twinotter
    You are correct, most trucks don't have independent suspensions, and most have solid axles. 42043 is similar to the real Arocs in this regard, however, the linkage set up on 42043 is very different than any real truck I have seen or driven. I'm skeptical because the links don't appear to account for any sideways motion that would occur when the axles get crossed up. It looks like a few other suspension parts may be stressed as well, but I'll have to study some better pictures to really tell for sure. Just my $.02.

    I'm looking forward to purchasing this model. This looks like a fantastic model. The longer cylinders will come in handy. I'm a bit sceptial of the suspension design, and it does't appear to allow a full range of motion. That being said, I'll reserve final judgement for when I see the model.
  21. dhc6twinotter
    I'm currently working on a road grader, F4U Corsair, and a forwarder (on hold for a while). I'm also working on a fully articulated tandem drive axle assembly for a yet to be determined truck. I may end up with two different axle designs. Other projects in the planning stages include two different tow trucks, a feller buncher, telehandler, AC700 crane, four different trucks, and some other things I'll probably never build.

    My Piper Super Cub uses a variable pitch mechanism that uses a differential to adjust pitch. It works very well and is very precise, especially if geared down a bit. Might work for your application.
  23. dhc6twinotter
    This is fantastic! Very clean lines, and I love all the details, especially the sway bar on the rear suspension.
  24. dhc6twinotter
    This is fantastic. I love everything about it. Looks like there is a SBC motor in it.
  25. dhc6twinotter
    I'm sure 42006 could be modified to work like an excavator, but I'm not sure you could do it using parts solely from the set. You may need to add some parts.
