  1. They are compatible, just tested it
  2. Hi, Herewith I would like to present my modern day interpretation of the classic 8480 Spaceshuttle: I started this model already 2020 (!) based on the idea that I could use the PU motor to select four positions in a function selector gearbox. In each position I can then run two functions simultaneously by adding two more motors. At the time I had the naive hope that LEGO would provide a proper PU development environment where I could make and share profiles with others. That never happened as we all know... So after a few years of waiting I decided to redesign the model for PF motors as well. The function selection now needs to be done manually as the PF servo motor can only be used for three positions and not four, so that couldn't be used. The functions are thus divided in four groups: - Landing gear bay doors + Landing gear - Cargo doors + Robot arm lift - Robot arm rotation + Satelite solarcells - Pitch controls + Roll controls Here is a simple gif to show the landing gear and landing gear bay doors in open and closed position: The cargobay is jampacked with the PU box, the robotarm and a satelite: The robotarm can rotate and lift, and the solarpanels can fold themselves out with a double hinge mechanism. In the PF version the batterybox is moved into the stand as it didn't fit inside the cargobay. In hindsight that would have been a more elegant solution for the PU version as well, but at the time I wanted to keep everything inside the model, just like the 8480 version. The pitch & roll controls use a mechanical subtractor mechanism to combine the two signals to move the elevons on the back of the wings. All in all it was a very interesting model to design. The function density is super high, which I always like. Too bad that the PU support has been so lackluster. A friend of mine has made a fantastic control profile in the SBrickPro application, but sadly also that application is still in beta and profiles can't be shared. Thoughts, comments and feedback is welcome as always. Oh, and instructions are available on my website for both versions.
  3. Is there a big gearrack in the back that is connected at the bottom of the links that connect to the top of the rear boom? The links that are just in front of the bigger links going to the counterweight. If so, it can be used to adjust the angle of the rear boom, but that will also change the height of the counterweights…

    [WIP] Pagani Huayra

    Hi, Here is another update: There is still some work to do, but the end is in sight. I finally solved the gearbox issues. It is now shifting in the right order with a snappy shift. I used 2L rubber blocks for the pretensioning of the stepper mechanism. The gearshifts 4->5 and 5->4 do require the most force, but when applied in the right way even those two work. You can see the aeroflaps on the left side activated, as the car is steering left. The rear clamshell doesn't have a opening linkage yet (which will be a challenge as it probably needs to be a 4-link system instead of a simple hinge). The front clamshell has some parts that need further securing. The suitcases are still missing
  5. No updates on this one I am sorry to say. It is still on my backlog and I am still intending to finish this model. The moment I will start again with this I will post it here.

    [WIP] Pagani Huayra

    Sorry for not posting anything sooner. This build has not been progressing as fast as I had hoped. Before going into that here is a photo of the current state of affairs: It is not very clear from the photo, but most of the yellow you see is actually bright light orange (basically all, except for the chairs, the flexaxles and the instrument panel). It is one of the cleanest interiors I ever designed I think. The reason for the long delay in the update has been the gearbox. I started the design with a transversal mounted gearbox (like I had in my 1:10 version as well), but when I tested it in real life the friction was just prohibitive and it was cracking gears in half of the gears. This set me back big time as I had designed the chassis around the gearbox. So I started the whole process again, but now with a more regular oriented gearbox. However, since the D/N/R switcher is controlled by the gearshift stick I needed to place that part in transversal orientation. Which was a pain the a**, as the engine is longitudinal oriented, so that requiredat least two 90 degree bevel gear connections. The location of that D/N/R switcher was another headache. I first wanted to put it below the engine, but that pushed the whole engine up, which made it interfere with the cross tubing above it. Then I tried to put it behind the engine, but the space there was too tight and blocked even more of the tubing. In a moment of inspiration I decided to rotate the whole D/N/R switch 90 degrees (to make it longitudinal) and place it between the shocks of the rear suspension just above the diff. This solved all the space issues around the engine (and by rearranging the gears I could even move the engine one stud lower), but as I now had to add a linkage between the driving axle for the D/N/R switch I could no longer use the white axle-connector to keep the switch engaged in D/N/R positions. So I had to make a mechanism to keep the switch locked in three positions (I currently have no photo of this mechanism, I'll post it when I have it). So I finally thought I was out of the woods with this gearbox, but then I found out that the stepper mechanism doesn't properly engage. It is a variant of the Porsche stepper mechanism, which is a bit more fickly than the Bugatti/Ferrari version. I still have to solve this issue, but once that is done I am pretty far as the bodywork is actually quite far. All in all, I am quite pleased with the state of the design as it is now. The chassis is incredibly stiff due to the use of two 3x19 frames per side (hidden from view behind the 3x13 curved panels), I am really fond of the interior design and the outer shell is starting to flow as well. The front suspension can be lowered, there are working fans in the front (the eagle eyed reader may have spotted that already) and the aeroflaps are working both in the front and the rear. Hopefully I'll have some time in the coming weeks to make more photos to show a bit more of the progress.

    Wow That is just gorgeous. Instantly recognizable! Very, very well sculpted. And buildable in multiple colours is the cherry on the top! This is Firas Abu-Jaber level I recon...
  8. When I worked there we did about one (flagship) model per year with two designers. Don't underestimate the number of iterations required to meet all the requirements that need to be met. I've made literally hundreds of variations of the same model to get it perfect. Of course my experience is now nearly 25 year old, so I would expect that things work differently now.
  9. LvdH answered already: I use Brickset to list the new parts. There they also indicate whether parts are available on PaB as well: The list isn't 100% accurate in that respect though, I found the small red helicopter blade on PaB, while Brickset lists it as March release that is not available yet.
  10. The January parts have appeared again on PaB...
  11. I like your thinking. Could that softer material have anything to do with their quest to get away from oil based plastic?
  12. Shouldn’t all the replies be hidden by spoilers? Or answered via PM? Otherwise @allanp’s friend might infer what’s going on…
  13. Wow! This is like a supercharged 8258. That crane is just insane. Very well done. Do you have a photo of the engine as well?
