RaZeR Posted October 19, 2009 Posted October 19, 2009 Thanks for the photos! I hope i will buy 8049 Log Loader, because i havn't got pneumatics in past (but now i'm collecting some money to buy...) The boxes if you're interested Thanks! Quote
CloneCommanderDelta7 Posted November 17, 2009 Posted November 17, 2009 3 of the new pneumatics would do great on the 2008 excavator, in fact pneumatics were made for it, as you would be able to control two arms and the bucket without gears all along the arm. Quote
Jetro Posted November 17, 2009 Posted November 17, 2009 Well, that's probably an old discussion, but as much as I like pneumatics, LA's give a more realistic movement to the two functions of the arm, you can easily regulate the degree of expansion/contraction. They are simply different mechanisms with different uses and applications. Quote
Brickthus Posted November 27, 2009 Posted November 27, 2009 (edited) Well, that's probably an old discussion, but as much as I like pneumatics, LA's give a more realistic movement to the two functions of the arm, you can easily regulate the degree of expansion/contraction. They are simply different mechanisms with different uses and applications. You can easily freeze the positions and control them variably without complexity, yes I'll have to try closed loop pneumatics in more applications. That would be the most realistic replacement for hydraulics in real life, except for the compressibility of the air, but the closed loop compensates for that. I quite understand why TLG went with LAs: - to remove complexity from the user (who is aged 7-11). It is in keeping with the 'instant gratification' generation - to complement the PF motors (which helps the business case) I think LAs ticked all the boxes of Quick, Simple, Cheap and Popular, so they were bound to happen! My first excavator kit was 8851. I thought it simpler than the one in the 8888 ideas book, which used gears, but that was all there was before the first pneumatics! I think it would not be wise for Lego to place one big pump to motor. Because it will result in air to flow in waves...cylinders will work in waves, too. It is better for a model to have multiple pumps, to provide constant airflow to fed cylinders.One big cylinder in good for manual pumping, but it requres gearing down, thus speed of pumping is reduced and air flow is even more flowing in waves I agree that smooth air delivery is a good thing. I use a car tyre air compressor for some pneumatic models and it's noisy with having only one cylinder. It needs 4 Amps at 12V too so a lot of power seems to be wasted! My swash plate pump currently has 2 mini compressors but I have run one with 6 and there is room for more on the frame. It uses an XL motor, which is powerful enough, partly because it is compressing only one pump at the maximum pressure point at a time. It is also a variable output pump because a lever can set the travel of the mini compressors by changing the swash angle. These pumps are used for real on aircraft engines and early 90s car diesel engines. Mark Edited November 27, 2009 by Mark Bellis Quote

Yes it is an old discussion but that won't stop me from saying PNEUMATICS ARE BEST FOR A KAGILLION REASONS over and over again Quote
Jetro Posted November 27, 2009 Posted November 27, 2009 Oh and I completely agree with you. Pneumatics anytime. As for air supply, what about this Quote
allanp Posted November 28, 2009 Posted November 28, 2009 Oh and I completely agree with you. Pneumatics anytime. As for air supply, what about this That's awsome! For a huge MOC excavator I have used one PF XL motor and 8 pumps which I recently purchased from bricklink to power the pneumatics and the power was simply epic! The SPEED and CONTROL and RESPONSIVENESS and SHEER BRUTE POWER of the thing was just so increadably life-like and ultra cool! Your compressor has TWO XL motors so I bet that's really powerful . All I have to do is build the compressor into a much smaller and compact unit which will enable me to fit it into the model around the 3 gearboxes. After I finish that I can start working on the closed loop pneumatic power steering concept. Quote
steele Posted December 1, 2009 Posted December 1, 2009 Not sure if this is news, but I bought 8046 at TRU today, and saw 8045 and 8049. Quote

steele Posted December 1, 2009 Posted December 1, 2009 (edited) Ok, here's a few (it's nighttime now so the flash was about the only light source). Tried to take pics of the more interesting bits. The hook at the rear is attached to a pulley that only has "friction" as a mechanism---it is simply held in place quite stiffly, and the gear is only so you can get a grip to force it to rotate. The rotor mechanism works very smoothly---you can make the entire system work by rotating any of the parts (rotor, tail rotor, or the actual gear you're supposed to use) (this one didn't turn out well despite several attempts to get a good shot of the hook and pulley---the pulley is easier to see in the previous pic) BTW, all of the "Y" rotor pieces are pearl silver. Also, a 3-long axle with stud in dark tan. (2 of them actually) Edited December 1, 2009 by steele Quote
tomacwhite Posted December 1, 2009 Posted December 1, 2009 Nice, looks great :) I wonder if these are available in the UK yet, has anyone seen them? Quote
merman Posted December 4, 2009 Posted December 4, 2009 I just bought and built 8047. It took about 40 minutes. Very cute little set. I made a lot of pictures and will write a review, but no time at the moment. Here is a picture of all the new parts: The back of the new gear: The partlist: Quote

merman Posted December 11, 2009 Posted December 11, 2009 (edited) 8041 looks like a Racers set: http://209.85.229.132/search?q=cache:TZT2Y...=clnk&gl=nl even though this is the B-model and it is on the Lego technic site! The first image of the 8041 B-model Edited December 11, 2009 by merman Quote

This B-model doesn't look very inspired. V8 engine though. Ready for a quick round of motor racing? The real chain transmission maked the 3 Cylinder engine work. The front and back suspension, new wheels and standard make this motorcycle hyper realistic. Can also be built into a chopper Could we be seeing some new type of transmission in the motorcycle??? Or is that just simply saying that the chain turns the engine? Seriously though, how many motorcycles do we need? Quote
Milan Posted December 11, 2009 Posted December 11, 2009 These truck sounds very nice... Hope we will have more infos about them! Quote

Blakbird Posted December 11, 2009 Posted December 11, 2009 Finally another racing truck so I have something to sit next to my lonely Silver Champion alternate model on the shelf. I quite like it. It has the same Rhino logo as the 8285 tow truck, so I'm guessing this is a Uwe Wabra design. It is hard to tell from the picture, but I am hoping that this thing has the slighter fatter tires from the Nitro Muscle set. Nowhere else to get them. They are practically the same size as the 8880 tires, but not quite. Quote
JunkstyleGio Posted December 11, 2009 Posted December 11, 2009 Does anyone have an idea on what is written on the left side next to the red brick? WANTED...... Or maybe LIMITED......? Quote
Blakbird Posted December 11, 2009 Posted December 11, 2009 (edited) Does anyone have an idea on what is written on the left side next to the red brick?WANTED...... Or maybe LIMITED......? Looks like "Limited Edition", whatever that is supposed to mean. Here's the alternate model: There are some good things here including the new large panels in black. Edited December 11, 2009 by Blakbird Quote
Milan Posted December 11, 2009 Posted December 11, 2009 Yeah, it is "Limited Edition". Which means, more expensive. Quote
