  1. Well, I do admire your ambition. But I would say that it will be very difficult driving those rear wheels unless you use some sort of final reduction in the hub. A typical axel coming from a differential will be subject to twisting from an XL motor, due to the turning diameter and momentum needed. As a push along model you will have no problem. Have you ever thought about why LEGO do not use wheels of this size? As has been pointed out, you will need to drive from a central differential due to the variation in wheel size. Also have you ever thought about having it front wheel drive only? As if you are having a loader on the tractor, then traction at the front end would not be a problem. Finally, your front linkage top link needs to be reworked, as it will just pull apart under load. Of course I would love to be proved wrong in all these issues. I suppose we are all learning. Happy New Year
  2. The whole model looks good except for the white pin connector on the landing skid. They could have used an additional black 3 long straight connector, just like at the end of the skid, and used a 2long axle to connect to the front bend, and then a shorter axle instead of the 10 long axle used. But I suppose this has to do with part count and warehouse logistics.... Nice Review, but I wont be buying the model.
  3. The first two photos of the Mack Anthem Lego model actually caught me out, as with the scenery and sunlight etc, I did not realise that this was the Lego model. Some really nice photos here. Well done.

    [MOC] Pendulum Waves

    This is the best bit of "Lego Therapy" I have seen for a long time. The project is very well thought out.

    [MOC] Grapple Truck I6

    Despite having a powered rotation, why did you put it in neutral and manually swing the arm when holding the apple?
  6. Really nice looking Scissor Lift. I have one, so I know a little about them. Many of the smaller ones can fit through a standard door frame. The smaller ones are electric/battery powered and the drive wheels are the steering wheels, which can handle an even tighter steering lock than what is available on your model. I am curious though, is it camera distortion or some major stress on components in your video at 2.28? I do realise that there are major stresses on the mechanism of the real one, especially for the first few metres of the lift. Well done anyway.

    Beamless Chassis Design?

    Without the beams, I think you would have a lot of kids who would never finish a model. The build would become so tedious that they would just give up.
  8. 90% or more, it still is very impressive. I think those people have been thinking outside of the box[brick] in many of their solutions. Full credit has to go to the human resources and training teams at Lego, as they have sourced some incredibly able builders and engineers. I think this is a massive promotional lift for Lego Technic, and brings a dynamic form of building into the public arena. It is a great improvement over the previously brick built life size models previously seen.

    Technic Prototype Parts

    I would say that if we went down the route of having no middle stop in the pins, and imagine Lego adopting it, think of all the problems that it would also generate. As previously mentioned, pins could be slightly out of place, causing trouble for the first-time child technic builders, but also we could end up pushing a pin into the belly of a machine, into a gearbox for example, resulting in a major strip down to retrieve it. A life without boundaries is not always the answer, stick with the middle stop and plan your builds better!
  10. Presently I did not have many lime panels. What I had was the metallic green from 8466. I just had to work the panels in where I could. I think we have to look beyond the panel colours, as some builders like myself don't have a full palette of colours or sizes. The pneumatics operated rather fast due to the build up of pressure in the tanks. The operator did not ease the valve slow enough. I was just so glad that the machine was very reliable throughout, as the buggy motor is deeply positioned in the belly of the machine and would have been difficult to access.
  11. I present to you a project which has been sitting completed for some time now. The need for its parts has prompted the video below, before the machine is dismantled. Now before anyone gets too excited, this is a very rough representation of the actual machine. My main focus was on getting power transferred efficiently from a buggy motor to the side mowers, and also permitting the range of movements that are required. This would normally be accomplished with high tension belts, but I had to opt for a continuous driveline with minimum bevel gears, and maintain high efficiency. The pneumatics are pressure controlled through a switch, and facilitate the variable ground clearance on the front axle, as well as the lowering and raising of the side mowers. The batteries were a little depleted at the time of filming. All other functions are described below. Pneumatic compressor - M motor Front mower lift - M motor Front mower operation - M Motor Side mower operation - Buggy motor Mower switch on/off - Micro motor through pole reverser switches Steering - M Motor Drive - 2 XL Motors 2 PF Battery boxes are used, and three PF receivers Enjoy! I would welcome your comments.

    Could do with some Lego flex system parts there.

    Axle colour - which would you prefer?

    I was brought up on the 2L, 4L, 5L, 8L, 10L and 12L axles, all of which were black, and the 2L had no notches! The 3L and 5L came in black, before the odd numbered revolution in LBG. I welcomed the grey colour and even the red 2L, as by looking at a model for a partial strip down, you knew what length each part was, and more lately what each part in a pin hole was. Where possible I do like to co-ordinate the colours on a driveline, or in an ancillary function, and the various colours allows for this to a point. Those tan 4L axles will save significant wear when used with the red 16T clutch wheels, minimising DUST.

    I would say that this set will fly out. it has enough scope if you didn't have any other Technic sets, to be able to build other things. Good mechanics and functions. Will sell better than the BWE.
  15. Reading over everyone's views, I have little to add, but that it is the new features and parts which keep me coming back for more. Longer pneumatic cylinders, curved gear racks from BWE and the newer Class Xerion tyres all keep me interested. Lego technic is always improving in its parts inventories. However as has been pointed out, the quality of the steering geometries and heavy steering, with Unimog and Chiron are the let down. On the whole things are looking good, and over the past ten years I have reared up a few more fans, which can't be bad!
