Maybe it was designed as bad as the mine loader, and they decided not to offer it. -
That's a shame. The fire truck was one of the 1H sets I would have considered buying. The mine loader thingy should've been canceled. That is the worse Technic set Lego has offered in a long time, IMHO.

Technic General Discussion
dhc6twinotter replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The old sampsonite gears may work, but I've not tried it. -
My initial plans wound up being about 25,000, so I've gone back to the drawing board.
-
I think restrictions force us to think more creatively. The builders on EB who can adapt to the different contests are the real pros here, IMHO. I'm used to building motorized MOCs larger than 10,000 studs, so this is going to be a fun but challenging contest for me.

Does anybody here use the 4' LED strip lights like this? http://www.lowes.com/pd_595731-43921-MXL2006-LED2X24K840_1z11k3pZ1z11owhZ1z140qi__?productId=999911231&pl=1 I'm wondering how well they work. I don't like the flicker the many fluorescent lights have, and I'm thinking about going LED once I get my LEGO room set up. I need to find some nice organizers too, and this thread has been great for ideas.

That is awesome. The technical design of this is just fantastic! Love the the way the ramp and upper deck is designed. Brilliant work there.

I wouldn't be surprised if there is no BWE, and all this is a result of confusion caused by the wheeled excavator and bucket wheel excavator names being so close. Maybe that's just wishful thinking on my part, and a BWE doesn't sound that enticing to me. I'd much rather se the Xerion or Volvo as the $200 set.

The engine sits pretty high in the chassis, so my guess is the chain connects the engine to drive shaft. Steering shaft may run inside the chain to HOG steering located on top or rear of trunk. The LA is probably used to open the body of the car upward.

Well, for not knowing these trailers exist, I think you did a pretty fine job building one!
-
That's a very nice truck and trailer! Looks like a fun project! I'm not sure if you are aware, but trailers like this do exist in real life as well: The video gets more interesting at the 3:00 mark.

I think the light blue color is the same that was used in the hotrod last year, as well as the dune buggy thing from this year.

1:10 3:6 16:4 7:3 10:2 18:1 Great job all!

Perhaps two mini turntables are used, with one mounted above the other. Upper rotor would be connected to the lower turntable by an axle that runs through the upper turntable. A single 20t bevel gear with a half stud offset could mesh with both mini turntables. This would be a very simple way to get the counter-rotation with the same speed in each rotor. Does the Chinook B model have a mini turntable on each rotor? I do like the idea of a 28t bevel gear. I could certainly use this. With working transmissions in a few sets this year, I would not be surprised to see new gear ratios.

Sort of. If you use the pole reverser method, each function would have its own pole reverser and motor. Half the pole reverser would be in the off position, and the other half would be on. Another motor is used to determine which half is on or off. So, if you had 8 receivers, you could use 14 pole reverser (doubled up on the receiver outputs), 14 motors, and one additional motor to switch which half of the pole reverser a are in the on position. The top portion of the diagram Blakbird posted has a similar layout for four of the motors. For pneumatics, you could have motors connected to 7 valves. Each valve output (two per valve) is connected to the input on another valve, which is then connected to the cylinders at each function. Half the valves are in the open position, and half the valves closed. A motor is used to determine which valves are open or closed. So, if you were to use pneumatics on all functions, you would have 21 valves. I'm working on a road grader that uses the above method, so I'll have pictures up in a bit.

I like those new panels! Looks like there are yellow and blue available. I wonder if the red handle on the race kart does anything?

The 8043 Excavator is a good example of how this can be achieved. It uses 4 motors to drive 6 functions. It used 3 motors to drive the functions, plus a motor to switch between the functions. I used a similar setup in my Backhoe, although I used 4 motors to drive 8 functions, plus a motor to switch between functions. So, with a single gearbox, you can build a moc that has 14 functions. You would have 7 motors going through a two position gearbox, plus one motor to switch the gearbox. You can also use more then one gearbox for many more functions, but playability gets worse. Banks of PF switches or pneumatic valves can also be used to duplicate functions. Some people have also used a motor to turn on/off battery boxes. Just my $.02.

1 FB, 1 GE, 3 PS, 1PC, 2 PR, and 1 DA. None have been opened yet...lol.
-
I agree with efferman. I would not be surprised to see new RC elements. We may also see a new motor to replace the XL, which has been discounted for a while now. Otherwise, I'm hoping to see the 42039 fenders in new colors.
-
Lol! Actually, the 3.8 motors were really good motors, as were the LS V8s in the GTO and G8. But yeah, if you had anything else under the hood, there was probably good reason to have the hood open. Honestly, it seems that GM only makes good pushrod engines (2.8 V6 being the exception--horrible motor). Just about all the overhead cam motors are rubbish.

Sorry, I meant 13L steering rack (I always wished for a 9L one though!) You can try putting larger gears on the steering rack, but I don't know that the servo is powerful enough for this. You could also try gearing up the servo, which would have the same effect as putting larger gears on the rack, but this adds slop, and slop isn't something you want with a servo. I think it will take some trial and error to figure this out, but that is part of the fun.
-
If you are already using a 9L rack, you can use larger gears on the steering rack. However, using a larger gear on the rack means the servo has to work harder, so this may not be ideal for your 5 axle steering setup. Using a shorter steering arm will also sharpen the steering angle, but your steering arms are already 3L on the front axle, and this is as short as you can go (you could try 2.5 though). I think your only option is to use a larger gear on the rack, and if the servo can't handle it, switch to an L motor. Or, you could build a truck to pull the trailer, and just have the servo connected to the front axle of the truck. The trailer could then have self-steer axles, or no steering axles at all.

There seems to be a bit of misinformation here. Many, if not all, DSLRs now have full auto mode (not that you want to use it though), and the ability to use the screen to view what you are shooting. My nearly five year old Canon T2i can do both. I use my old T2i for taking pictures and video of my Lego creations. I've been pretty happy with the pictures it takes, but I'll be upgrading to something better in the near future. The lens I was using seemed a bit soft, but I picked up a 50mm prime which seems much sharper. Proper lighting is also important for good LEGO photos. I would suggest picking up a DSLR and a 50mm "nifty fifty" prime lense (they are about the cheapest lense out, but they are actually pretty good).
-
Ideally, yes, you would want all steered axles to have varying amounts of steering. If the axles steer at the same angle, then the axle with the most weight on it will probably be the dominant steer axle (I think). For crab steering, you would want all axles to steer, and steer at the same angles.

Modular Building Sets - Rumours and Discussion
dhc6twinotter replied to The Jersey Brick Guy's topic in LEGO Town
I hope either GB or the new modular will be revealed at BrickCon in 2 weeks.
