    Your Best Technic Bargains

    Agreed, I actually think about cutting them flat (I mean the other ones I have in good condition) and making a huge poster out of them...

    Your Best Technic Bargains

    Today's catch, found on a local 2nd hand website, including all instructions: 42042 (with damaged box) 60€ 42053 (with damaged box) 45€ 42065 (with damaged box) 25€ 42033 (no box) 5€ 42045 (no box) 5€ Total 140€

    Compact mechanical inverter

    Thanks @suffocation for the information. It is indeed what I was expecting. Too bad, it would have been quite simple!
  4. I need a mechanical inverter for a current moc, and I was wondering if someone have tried to use the new blue clutch gear to make a compact one like pictured. My concern is that the old driving ring may not be compatible with the new blue gear, and secondly that the driving gear touches the thin bevel gear and generates friction/damages the parts. Since I do not own any blue gear, I was wondering if someone would try.

    Electric cars don't need/have gearboxes because unlike internal combustion engines, electric motors have their maximum torque at low rpm. Check out Tesla cars for example: no gearbox. As @Sariel pointed out, in the case of Lego cars/trucks, a gearbox is only useful to adapt to the load on the motor depending of the driving conditions (slope, trailer, ...). Basically, an electric motor gives its maximum power at moderate rotational speed, whereas a combustion engine has it's peak power at high rpm, around 4000-6000. Basically, cars have gearboxes only to gear down the engine to get moving, because they have low torque at low speed, but once they gained enough speed, the gearing can be increased. Here are typical torque/power for both electric and combustion engine. Torque/power for electric motor: Torque/power for combustion engine:

    Bugatti Chiron W16 engine (mini-sized)

    nice improvement! It looks almost too short or too tall now, but you can probably reduce the height by cutting a little the oil pan underneath...

    42083 - Bugatti Chiron

    @Didumos69, you're totally right, that's why I called it an attempt. Initially I just wanted to check if it was possible to get two rows of pistons closer one from the other than what we can see on the video. Obviously using the technic motor cylinder it is impossible, that's probably why the one from the official video looks way too tall compared to the real engine. Also, I wanted to test the feasibility of having a single crankshaft, because as pointed out by several members here, the one from 42083 is likely to have 3 crankshafts. However I did not spend time to refine the design, it is basically a preliminary sketch where I tried to get all the essential parts where I wanted them to be using the smallest amount of parts. It turned out not so bad so I decided to share it, but did not optimize it at all for structural strength. @Jaromir, I used LDD to model it. I do not plan to build it now, but who knows...

    @JunkstyleGio Thank you, you are definitively better than me for rendering! It looks amazing. Also I just discovered the last LDD update, maybe I should quit and reload the software more often...

    For those interested, I have my version of a W16 single crankshaft here:

    I might share it, but Ldd does not have those curved tiles, so I transferred the design to to add them and render. Also I am pretty new here, so I don't know how to attach a file larger than 0.1MB

    42083 - Bugatti Chiron

    Thought you guys might like my attempt at doing a W16! It is a bit longer than the one visible on the trailer, but has a nicer look IMO. Of course it has a single crankshaft.
