Zero's workshop
thekoRngear replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Zero, really like this new style and actually prefer this over the previous one. Howevr, text on screen will always be a powerful format. MOCwise it is one great step forward! Just wish the vulnerable electronics get to protect with something more stylish than plastic in future -
Guys, regarding gearbox I have observed something which might sound interesting. I am not expert in gearbox mechanism anyways. Below in the picture is the Technic Defender 42110's 4-speed sequential gearbox mockup with tweaks borrowed from the Pimped Up version. The Pimped Up version has those rear 16t gears (it is 20t and 12t double bevels in the Pimped Up, I kept it the same as original gearbox) supported by longer axles. In the original gearbox, those 16t gears are connected through 3L Stop axles. The Pimped up version replaces them with longer axles with no stop and, a T beam is also attached on top of those 16t axles. The bottom single hole is attached with the blue pin. What amuses me is that if that T Beam is detached the gearbox works more freely. When the T beam is there, it feels as if the gearbox is having some kind of resistance. This is not the only instance I am describing here. A month and half ago I had to tweak the McLaren Senna GTR MOC (from 42115). Its 8 speed sequential gearbox has couple of points similar to the pictured one where 20t and 12t double bevels are paired. I saw if I don't use 3L stop axles and use a longer axle (just one stud longer) without any support (such as the T Beam in this case) they move more freely. I kept that longer axle but open. Looks definitely bad but the whole gearbox gets to spin and mesh freely. Since it was one instance I did not think it was necessary to tell about it anywhere. But now that I observe it again can anybody tell me what actually is happening here? Has anybody tried that out before?

I second this sentiment from you along with another one where you said Technic Flagship is now more about breaking price and part count record. I guess Technic is done with itself and is now out on a mission to glorify non-Technic themes like the DeLorean or AT-AT or the new 10303 Loop Coaster set (don't take this sentiment too seriously, sarcasm is here). This year looks so bad from pure TLG Technic perspective that even an ordinary (yet proper) Technic set like 42139 feels like a huge splash of water in a desert. BTW is this set having a differential or is it needed at all for a type of set like this?

Guys, although there is no official words from TLG, it seems the 42146 won't be coming out this year. And with that I am afraid this year is one of those underwhelming (a bit, least to say) Technic years. I think TLG could make a compensation for that by releasing a set surprisingly (which is unlikely). And, the 42142 at this point is still an unknown face. I guess it will see its release towards the end of this year/beginning of next year.

Saw this a while ago on Racingbrick's FB Page. A pic with a closer look at the turntable is also there. I have concerns that it will be wobbly (as usual). I liked what this dude (from promobricks) did to the turntable which was posted few months back here. I am actually more interested in what MOCs folks will come up with this. A side-benched 20t double bevel gear is also seen now befriending with a little worm gear

Are the Lego tyres more prone to collecting dust/dirt as time flies? My Defender's (2.5 year's old) wheels, when run on the floor would not collect dust as much as they seem to be doing now. Same floor, same state of cleanliness, yet the tyres seem to gather dust/dirt on them much more quicker. I started to noticing it one and a half year's later.- 5,509 replies

That could be risky as the one from Pimped Up Sian seems to be a really good one [I can tell it from using the Ford F-150 MOC] but if JB70 and didumos69 come up with something even cooler I will be happily welcoming it. Edit: I thought you meant the pimped up version of Sian. Since the Ferrari has the same gearbox as the Sian then the pimped up version [if that happens] of Ferrari will also have the same modified version from the PU Sian @jb70 will we be seeing a Pimped Up Ferrari this year? Would be exciting if the gearbox made even quieter and smoother.

Ah, after a "long time" I finally see some real/proper Technic sets pics. Really like the 42144- looks a like a "spiritual successor" to the Big Red. Really do not like yellow in the white-red tone of the 42145 beauty, that's a minor complaint from me though. I have some worries- the errors in the manuals of 42143 should not pass onto the other H2 sets as well.

Why slow? Why so much torque and less fast speed? Are those all made by keeping in mind only the crawler/off-road types and also construction vehocles? What's your opinion on this? I still think, although the 42129 is made specifically for rough terrains/pure crawling, should also have an option to move faaaast on plain surface. If I ever decide to buy a Zetros I'd def consider @Ngoc Nguyen's no electronics mod with the electronics to use in a moc or something else.- 5,509 replies

42110 - Land Rover Defender
thekoRngear replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello Viktor! My Jeep Bruiser is about to hit its 5 months anniversary cometh this June 8th There were some steering related issues which were ironed out with your immense help and insight in between January and February. Ever since then I realized the Jeep Bruiser is something I cannot live without. The 42110's outer body shell is also something I cannot live without. Hence, I decided and went on to buy the 2nd Defender. Congrats! Now, if I am to point out rigidity/sturdiness support for a monstrous gearbox system (means the 4 speed gearbox, the reverse gearbox system with the centre differential, the distribution gearbox in the mid console, and ultimately bunch of gears in the front to connect with the gearbox) I must say Your one is most refined, sturdier, cleverer and best available solution with the given parts available. Now, lets say someone has not made any errors in the process of building the 42110 set, the chassis structure itself has some really challenging techniques that is proven quite hostile for the gearbox. Building the gearbox is a challenge, but in reality the chassis is also a challenge for the gearbox to run smoothly. For example, take a look at the module at step #84 That module is NOT just strong enough to pass the power/transmission from and through. I remember whenever I would drive the set in high gears that #32013 connector would get loose. Interestingly Racingbrick in his earlier videos thought of it otherwise. He thought the connector was loose and hence friction/tension was rising. In reality it was the complete opposite scenario. Each time I would fix the connector it just could not sit properly on top of the axle after a short run in 3rd or 4th gears. Also, the way the output goes from the u-joint through the 20t and 16t gears and finally the red 16t clutch gear is an absolute risky step/process. Then comes the Pimped Up version. This time the situation is different. The PU version replaces the 16t/16t gear pair with 12t/20t. IMHO, it is much needed for reducing the friction. There are some improvements from the very back of the gearbox to the point where the Engine gets engaged with the output. No cracking is there. But is it enough? Yes, there is no cracks but after several days gone, when the vehicle moves specially in Lo (and in highest gear) it would not run smoothly. You will just not feel good. It is like you are forcing the Jeep to move around. JB70's solution I guess best used in the Sian's Pimped Up version. Nico71 refined this 8 speed monster a bit and used on his Ford F-150 MOC which I had for around 8 months. Boy, that gearbox would not even crack, nor would it make that eventual unpleasant friction in its entire period The Jeep Bruiser, due its chassis design and your much careful thought is completely free of any cracks. There is no parts/modules get loosened. However, the gears would face struggles. The left rear 8t/24t gear pair would face forces and the 20t gear installed at #45 would tend to get slightly out of the place. I think in general the 8t/24t gear pair is notorious. A 12t/20t double bevel gear pair do a quieter job. Also, the rear live axle, in general, does not want to be nice with such heavy gearbox system (same happens to the 3rd gear of Stadium Truck MOC) specially when driven backward. Finally, either in Drive or Reverse, the Lo mode makes the gearbox insanely full of friction in 3rd/4th. They don't crack but won't allow the Jeep to move naturally. I think all these exhibits Lego's limitations, no designer's faults or such. Another observation I have made is, for heavy gearbox, if the vehicle is steered left or right, the gearbox and the whole drivetrain feels more forced than if it is driven straight forward/backward. It is applicable for the 1/8 scale Supercars too. So, after a much careful thought I went for the 2 speed gearbox that you utilized in the RC Version and made peace with it. Couple a months gone. This 2-speed gearbox is smooth and a bit moar badass than the super quiet 42139's 2-speed gearbox. The Jeep bruiser has those sexy doors, much well designed front hood, super stable winch system, probably best suspension system for the 42110 (and overall a pure class), cool central shaft with live axles on both end and a centre diff with a wise 7x11 frame housing, a perfectly working tailgate with cool brick-based solution to secure its position. So, why should I break so much sweat on that dense 4 speed monster. That 2-speed gearbox is enough to play with it. BTW, the whole steering system as a result of gaining space is now simplified and works fluently, the 16t gears trio is no longer needed!! Damn, if the electronics were not this much expensive I would buy them and make it into a RC one. In this context, I should also tell that the Defender has its flaws here and there in the outer body shell (some on nitpicking levels). Some stuffs start to becoming more visible after a few weeks (even if it stays still). I think Grohl has both the capacity and desire to make complex structures instead of using those 11x7 frames and 5x11x1 panels. Just imagine how creative and complex can a thing be in the space/size of those panels and frames! That also resulted in such interesting (and frustrating) situations for the 42110 model. -
42110 - Land Rover Defender
thekoRngear replied to 1gor's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Yes!!!! One of the most anticipated Technic videos is now out!!! Those who never faced the cracking issue don't come up by saying that before watching the video entirely. Sigh, the new gears still cannot fix it as I've suspected. Howevr, I can suggest Balazs to test the new gears using the JB70's pimped up version. As I've said in my last post in this thread, the Pimped up version will probably never cause cracking noise but it can be made quieter/smoother if the new gears are used.
