  1. Wow! The design is very well composed, using a high density of panels. The drivetrain does not use differentials, right? Does that affect the performance while cornering? When I tried this, the battery box would always shut down becaues of the extra load.
  2. I want to show you some more details of the bus. The bellows are more complex than they look from the outside. The maccaroni pieces at the top need to rotate freely, while the axles have to hold the liftarms and the maccaroni pieces at the bottom. This would be very easy, if 22l axles existed. we came up with a combination of end stop axles, frictionless pins and thin liftarms with axle holes. The 1x5 liftarms simulate the extra bellows that the real bus has in the lower part of the interior. We came up with a super compact i6 fake engine, 3x2x9 studs, which did not make it into the final model. The pistons are crank parts and the crankshaft (actually camshaft) is made out of headlight bricks. It was ment to be powered micro motor, directly from the battery box. Two of our favorite details are the camouflage u-joint and camouflage s-brick:

    Attachments -- and how to delete them

    Could someone delete both attachments from the first post in this thread?
  4. Yes, they are. The weels are always the first part when we build a new model. The bus ended up being 21 studs wide, because we wanted the corridor between the weels to be 5 studs wide. 19 studs would probably be more accurate.
  5. Done. Here are the pictures:
  6. I just uploaded one picture. Is there any possibility to upload pictures bigger than 0.1MB? While kneeling down, the air has to pass a half engaged switch. While kneeling up, the air can get straight into to the cylinders. In the beginning of the building instructions there is a pneumatic plan, which might help you.
  7. It has been quite a while since I last posted here. But this Project seems to be worth sharing with you. At 9869 parts and 8.4 kg, it is by far our largest project. The goal was to include motorized driving and pneumatic suspension without using any of the interior space. So yes, it has a real low floor going through the whole length. RC-functions: - The third axle is driven using 4 PF L motors, 2 CaDA metal u-joints and the new LEGO heavy duty diff. We destroyed many parts while prototyping. We tried to include a 2-speed gearbox, off-center diff, no diff at all and single wheel drive. The current setup is the only one which was working in the end. - The first axle is steered by a PF servo, located under the driver seat. - The bus has two separate pneumatic systems. One for the suspension and one for the doors. Both have their own manometer and pump, actuated by a PF L motor. The suspension system has 2 air tanks, the door system has 1. - The left suspension can be raised manually with a switch in the driver's cabin. The right side is operated by a PF servo. We included a check valve to enable slow kneeling. The switches are connected in such a way that the pressure in the air tanks is always kept while kneeling. The suspension system uses 22 small pneumatic cylinders and 10 shock absorbers. - The doors are also operated by a PF servo. The second and third door can be disabled separately from the driver's cabin. The system has a total of 6 cylinders. - We managed to hide a micro motor under a seat behind the first axle. It is used to unfold the wheelchair ramp. We used a red 9244a u-joint to hide the mechanism in the side wall. - A total of 8 LED pairs is used for the lighting. The functions are controlled by 4 s-bricks. For power supply we use one 84599 rechargeable battery box and one buwizz brick. The bus uses 14 extension wires and 14+ meters of hose. One of the hardest challenges was to prevent the bus from bending. The floor is only 2 studs thick and has weak spots over each axle. The roof is responsible for the rigidity while only being connected to the lower section with a few liftarms. It also houses most of the technic. There are several tight spots where every millimeter is used for hoses and wires. Problems: The suspension system is very unreliable. Many of the small cylinders leak if they are unevenly loaded. We had to buy more of them than we need and still the kneeling does not work every time. The front and rear section are only connected with one turntable in the roof and one pin in the floor which makes it hard to pick the bus up. The building time was 3 years with many breaks. We wanted to replicate the exact version of the bus which is used in Munich. Unfortunately all articulated buses with 3 doors were retired during the building process. It is very disappointing that we could not build it in blue because LEGO thinks it is a good idea to use 5 different shades of blue than releasing all basic parts in one color. As usual we published free building instructions at rebrickable: If you want to watch the instructions for entertainment, we also have a video version: You can find a very ugly pneumatic plan in the instructions. The bellows are a further developed version of Sariel's design: Also big shout out to the incredible CapaCity L by krolli:
  8. Do we already know the main color(s) of 42099? Was the set shown in Nuremberg dbg like the leaked pictures?
  9. We had slipping gears only when driving against a wall. Surprisingly we had no problems with the u-joints. The axels are also in good condition because we lubricated the whole transmission.
  10. Sorry, I have no idea how to upload pictures bigger than 0.1MB. I just posted some LDD renders of the drivetrain on Instagram. You will get a deeper look inside of the model when the building instructions are finished.
  11. The fast mode makes the Tesla pretty much double the speed compared to the slow mode. Buwizz also allows propotional speed which means the model drives in any speed you want from 0 to the maximal speed.
  12. Hey guys! After working on this model for more than 6 months, we finally want to show you our new Tesla Model S: Manual functions: - openable doors, trunk and frunk (front trunk) - foldable rear jumpseats RC functions controlled by 2x Buwizz brick: - RWD (8x PF l motor) - steering (1x PF servo motor) The biggest challenge was to bring the whole power to the wheels. The differential is powered from both sides and we use old style 9244a u-joints. What is your opinion about this high count of motors? Do more motors really make the model faster or do they only increase the weight and part wear?
  13. Thanks! It´s not a scaled model of a real snow groomer.
  14. Hey guys! Our latest project is finished. We hope you like it Remote controlled functions: - drive, steering - 4 XL motors - turn the crane - 1 M motor - winch - 1 M motor - 6 pneumatic functions - 4 servo motors Motorized functions: - raise the tracks - 1 L motor - pneumatic compressor - 2 L motors - PF lights
  15. Wow! You added so many functions to this set. Very clever to use a linear accurator for the pneumatic switches!
