  1. You've definitely have a great idea; however, I can see a few problems thus far. Firstly, all of the axles would have the same steering angle; however, if you can squeeze a space for gearing the servomotor, this wouldn't be a problem. Secondly, servomotors are 25USD each, which means that even on an 8x8x8 you'd spend 100USD on servos. A potential solution would be to to have an axle on top of the assembly that connects all other axles to all of the gear-racks.
  2. Search this topic: FYI I am working on a twinsteer front axle without drive using linkages and "leafsprings" so I will send you the LXF when I am finished.
  3. Very impressive at this scale! Did you ask yourself should you, before thinking about how it could be done? As a non-powered model, why would you add a function that is derived from movement? Don't get me wrong, you must have done some amazing work to fit all of this stuff into such a small scale, but do you think it makes sense? On a side note your front "leaf springs" look fragile, as the axle could pop out of the connector piece given a sufficient force. The added weight of a cabin may cause problems; however, the lack of heavy pf elements may make your system feasible. I have been experimenting with lego leaf springs for over a year now, so I thought I'd just give you my opinion.
  4. Simply beautiful! Your solution for the 3 wide windows is great!
  5. Simple: use gears to change the maximum deflection of the servo. 8 and 24 tooth gears will reduce the deflection angle by 1/3, so 30 degrees. Remember that two gears will offset the return position of the servo, so add 3 or more to solve this problem. Keep in mind that more gears increase backlash, which decreases the accuracy of your steering system.
  6. Your work is very inspiring and make it look like child's play. Wait, you actually asked the manufacturer to send you detailed information about the design? What was the premise on which you sent the email. Did you mention that you were making a LEGO model? I seriously hope that you get a response! One small observation, The 1x3 tile adjacent to the fake drive sprocket looks like it will just fall off as it is only held on by one stud. You might consider replacing it with a 2x3 tile, if possible.
  7. The body looks great, but the bogies are disproportionate. I think the frontmost axle on each bogie looks like it is one stud too close to the front. However the buffers are fine where they are.
  8. With that type of traverse speed your tank could be repurposed as a g force simulator. In all seriousness, I really love it! Did any of the four Buggy motors overheat after driving the tank around for some time?
  9. Stunning footage! Great video and such a unique idea. Thank you for sharing! Was there any problem with the train in the colder temperatures?
  10. Thank you both very much! After waiting 2.5 weeks for the ball bearings to arrive the package contained a letter from the seller stating that they were out of stock and an appeasement "gift." Two weeks later I received the bearings and began experimenting on how to modify my existing rolling stock. I decided on using a technic brick 1x2 with 2 holes, but quickly found out that the bearings could not be pressed in by hand. I used some pliers to squeeze them into the brick and fitted the metal axle in to adjust the bearing so that it was flush with the side face of the brick. This was NOT fun, but the result was worth the time and effort. I don't have or want a youtube account, so you will have to download the video from my bricksafe. Thanks for reading.
  11. Looks very realistic. How durable/sturdy is the virtual pivot axle. It appears that the lift arms could easily pop off of the wheel hubs. In your video you shifted gears without stopping; how smooth was this gear change while in motion,?
  12. Superb work! The tram depot is gorgeous; I'd love to have one myself. However, I think the other station is a little bit bland. You could add the clipboards as white 1x1 tiles to the side of the building and the electronic sign below the roof as shown in the last picture on the second post.
  13. You've got some great fire appliances! I'd like to point out that the wheels the on-road trucks look a bit too wide. I think substituting this part would make them more realistic. I know they don't fit on to the rims in LDD but in real life they fit snugly.
  14. Looks like you've got the overall shape; however, I feel the model is a little bit bland. For instance you might add a cap on the fuel tank, a latch on the toolbox below the trailer, mudflaps, hubcaps on the rear wheels, or the hydraulic and electric hookups on the rear of the cabin. From your photos, it appears that you have the space to add a cabin interior, but I might be wrong about this. For a model this size you could certainly spend a little time to significantly improve the overall appearance of the model.
