Those wheels are cool:

Well, the 8043 Motorized Excavator is now "Sold Out" on the USA Shop.Lego.com website. It had a ~27 month run (August 2010-Nov 2012), which is longer than most "flagship" models.

This is useful, but these units are missing from the chart: Power Supply = 9V Torque is in Newton-cm Speed is in RPM Mechanical Power is in Watts

@ piterx: Perhaps you could drive your MOC with the 8879 "Power Functions IR Speed Remote Control" unit, so that you could start off slowly and build up speed without breaking anything:

Welcome to Eurobricks! Your kids are nice to give you some Lego Technic. My son only gives me a hard time!

Great MOC! :thumbup: It is faithful to the real Peterbilt 379s driving on the American Interstate system near here:

[bUMP] As he showed on this previous post in this topic, Grohl (Milan Reindl) added to Rebrickable this Lego 8071 alternate build for his road Scraper. He wrote that it is "My own alternate for 8071. Length-33cm. Functions-Openable door Openable engine cover Working angine Articulated steering Lowering hopper Openable front blade Working Ejector. CAD file created by Baldwin Verhaar."

With summer fast approaching "Down Under", AussieBJ05 posted several YouTube videos of his Lego Technic 4WD vehicle with folding pop-up camper trailer. : Demonstrating the folding mechanisms: : Showing how the camping trailer opens (pops up):

Yes, Lego Mindstorms can really model some interesting ideas!

@ Lipko: Thanks for sharing your LDD .lxf file! You should consider submitting your excellent MOC to Rebrickable.com, where AFOLs who are not members of Eurobricks can see it!

@ Pretzel Robotics: Wow, that 8'x8' arena (shown below) is very spacious for your 6 Lego battlebots! "Lego BattleBot Building Rules and Regulations" "Here is a simple list of all the rules that all Lego BattleBots I create have to follow and abide by. There aren't too many of them, but these rules will help organize my events and give the viewers a sense of why I did certain things with my robots. Robots cannot weigh more than 950 grams. Fights are 3:00 minutes long. Drivers CANNOT interfere with the other robot by changing the channel of their transmitters. Doing so will result in an automatic match loss. Each robot can use 1 Lithium Polymer (LiPo) battery pack and 1 Lego extension cord instead of the standard Lego Power Function battery pack. This results in more destruction and a more exciting battles. Batteries must be protected and cannot be exposed. Batteries cannot exceed 11.1 volts. To prevent destruction of wires attached on Power Functions parts, wires may be taped to the motor, but nothing else. Other than LiPo batteries and tape on wires, non-Lego parts CANNOT be used. A robot cannot be declared immobile until a 10 second countdown is conducted. If the robot cannot show controlled motion after the 10 seconds, the robot is immobile. A robot is immobile if it cannot move in a controlled motion. A robot can only pin another robot for 10 seconds. After 10 seconds, the other robot must be released. If a robot is flipped into a position that prevents it from moving, it is counted out. If 2 robots are stuck together and cannot free themselves, the match will be paused and the robots will be unstuck. If Lego bricks on the arena floor prevent a robot from moving, a 10 second countdown will be conducted. If the robot cannot show controlled motion after the 10 seconds, the robot is immobile. If both robots become immobile at the same time, a judges decision will decide the winner of the match."

Kala82NotFound posted this YouTube video of a Lego Technic rotating pincer made in SR 3D Builder. It shows how one can do various rotations in the program: http://www.youtube.com/watch?v=xhSkbfKyZiE

@ Pretzel Robotics: Let the carnage begin!

@ MarkusOSX: Your Lego Technic 8x8 Trial Truck looks great! Yes, you should take it to the grunewald to test it out on the dirt!

Yes, it really does:

On MOCpages, Senator Chinchilla recently posted numerous pictures of his STUDDED Lego Datsun 240Z model. His shows all of its features:

[bUMP] On his Flickr photoset, Mostlytechnic posted 37 excellent pictures of all three of the Lego 8485 Control Center II 's models. The photoset has pictures of each model in various stages of completion. Here are the finished models: HOVERCRAFT: "The completed hovercraft. The long wires are used to make a wired remote from the control box to the craft. They run through some axles at the top center to keep you from pulling them off. It's a decent idea, but the cables still aren't near long enough to actually use this way. Granted, I'm a 6'3" adult, but I'd have to pretty much crawl to drive it on the floor. A couple flex cables are used at the back to "shroud" the "fan", but otherwise there's no rare parts in this vehicle. From the control box, the red A and B buttons provide forward and reverse (driving just one of the front wheels so that no differential is needed) and the yellow W and E steer the rear sheel." HELICOPTER: "The helicopter itself mounts onto the lift mechanism, and the wires connect to the two 9v connectors on the bottom of the chopper. Now it's a fully functional model. One of the best features is how the lift mechanism is stable at any position. It's pretty well balanced between the copter and the control panel, plus all the pivot points in the lift mechanism are friction pins." DINOSAUR: "Two of those legs, mirror images of each other, attach to the body and the base. They look great, even though they don't actually support any weight. It's a great way to hide the light grey support stand though." Read more about that set in this excellent Blakbird's Technicopedia article.

[bUMP] A few weeks ago, Mahjqa posted this Flickr image on his photostream to show "...how I add tracks to my LDD models. Since track parts don't snap to gears, I use constructions like the one on the left to align the first track link. After that, I use the hinge tool to place additional links."

I like the Mega Bloks wheels that you used:

osuharding1's gives a clue on how to fully motorize a Lego Technic 9397 Logging Truck. He wrote that it is a "brief video demonstration of how I have incorporated additional "power functions" to make "Lego Technic 9397 Logging Truck" fully "remote control".1 XL-motor drives both rear axles 1 M-motor for steering 1 IR Receiver 1 Remote Control 1 Set LEDs"

I like those grippy third-party tires on the Lego 44772 wheels!

In his Flickr photoset, LegoMarat posted 16 pictures and a Flickr video of his Lego Technic 1988 Honda Civic. The DETAILS are extraordinary for a car of this scale! It has front and rear double wishbone suspension; opening doors, bonnet, & hatch; folding seats; dual overhead cam engine; and 4-speed gearbox:
