After two months and maybe 30 lift-offs, my set has stopped working smoothly (though it never really worked smoothly to begin with). The string produces way too much friction; every time I played with it, the set seemed like it wanted to pull itself apart, and now it has started to halt entirely, especially during the "descent". Frustrated, I disassembled it only to find the CV joint basically grated. This is the first time I’ve seen something like this in 30 years of building. Quite disappointed by LEGO’s standards lately. Honestly, this set is poorly engineered; the structural alignment relies on long axles that come out of the box already bent. On top of that, the string is too thick for the 49283 pulley (at least in my set). The "crankshaft" that transmits power to the "gearbox" is held by a 32013 that relies only on a blue 43093 pin, which basically comes off after five lift-offs. Has LEGO stopped giving sets to children to evaluate if they actually stay together after some play?

If anyone is building this set, pay close attention to the suspensions. Some of the suspension pivots use friction pins; on the front axle, you might not even notice the issue until it's too late. I personally couldn't stand the squeaky sound and the lack of rebound—especially in the front—so I’ve disassembled it. I'm currently reassembling the model with a few 'bugfixes.' I'll share the results once I’ve finished the rebuild.

Yeah, something like a 2 stud long axle connector with axle orientation shifted by 120° at each end would be needed to offset each pair of opposing crankshafts (the cam is another thing). I guess they did something like a crankshaft offset by 180° for each pair of opposing pistons (so 6 crankshafts for 6 pistons instead of the usual 3 for 6), but the offset of the symmetry axis between each pair would be 0 90 180, so basically first and last pair would be the same.

Yep, that’s what I meant! Sorry if my English isn’t perfect.The orientation of each pair of crankshafts would be exactly 180°, if I’m not mistaken.

Mmm correct firing order of the cylinders... I wonder if Milan used 6 #4368 cranks instead of 3, with each opposing pair of cranks rotated 180° to each other, to achieve true boxer-style synchronized firing. The fact that the pistons aren’t aligned is actually another accuracy bonus for a boxer engine!

Hi, I'm a new member from Italy. I've been a LEGO fan since I was a little kid and I never really stopped building with bricks, but after the release of the Saturn V 2130, my purchases became less sparse . I know this might upset someone, but the whole craze around licensed car models is actually what kept me in the hobby . Recently I discovered the MOC community and started rebuilding some of my sets just for fun. I hope to have fun here!
