No-no-no, that's a change of a whole topic as you started it basically stating "Instructions based on stolen IP has been stolen! What can we do about that to still keep earning money?" What I think you wish to achieve here is to get ideas how can you get the most of your paid instructions for your MOCs. I have a first suggestion - don't base it on any existing IP. This will drastically reduce the number of people interested in buying instructions, but as well keep you low from Lepin. And this is where crowdfunding might actually work as it make sense. You can set a target of selling, say 20 instructions. Once target reached you could still continue selling the instructions for non-CF guys, but won't worry much if Lepin step in as you achieved your main target during CF phase.

It looks very nice! Lack of motorised driving is actually a good thing sometimes! It allows you to play around and show off the model quite quickly.

Ha, selling instructions for "non-branded" models that still look the same as some, let's say Lamborghini? That's still a theft. You might remember cars in GTA. Some of them were reminding existing vehicles, but they were severely modified. So you would need to do the same with your MOCs, which will reduce the popularity as cars won't be even close. If we dig deeper - theft is a theft, doesn't matter if it is small or big. We can use same logic from Lepin's perspective - this is not a big loss for MOC builders, may be even some kind of promo. I'm sure you won't like how it sounds...

I like the MOCs you guys produce. They raise a bar very high. However I might state not the most common point of view - my concern we might be talking about double standards here. Isn't profiting (selling MOC instructions) based on someone else's popularity (insert any car brand model) considered a theft too? I highly doubt you guys pay royalty to MB, BMW, McLaren, Lamborghini and etc. That's pretty much what Lepin does, but with MOC designers.

Receiving or selling?

For LEGO MOC the answer is quite simple - you consume the same 32x32 baseplate, but can build far more impressive building. In real life space is expensive, so building more stories in the given area allows to profit from buying the property. Living in upper floors is quite cool for some people.

Closest you can get is either this or this part. But they seem to be a little smaller than the ones used 31064, which might explain why LEGO decided to use brick-built propellers.

Nice little and recognisable car. Any damage after driving on gravel? Oh ant those wobbling wheels

No thanks. There were cases where several hour long conference videos have been banned or demonetized only because some has been playing a music in background during one of the breaks. Like come on, 99.5% of the video is original content. Why should someone else gain $$$ because of some minor issue? Ideally such system should be flexible, for cases I mentioned above, unlike it is "all or nothing" now.

Don't want to be harsh, but for me it seems like proportions a little off. You can clearly see this on a picture compared to blueprint: wheel base is a little too short, doors are wrong shape, and roof is stud or two too low. I like the transmission however, as I'm yet to build my own crawler I'm quite fascinated by other's builds. Have you considered using two L-motors instead of XL? They perform quite well on 9398/41999.

According to instructions dark gray gear is free spinning and is not attached to any other gears at the moment. So at page 76 it should not rotate if you turn any other gears.

This topic is going to be for all my train related MOCs as I do not intend to make separate topics for each one of them. Now a bit of a story. It all started in my childhood when I always wanted to have a train set, but never got one. Now that I'm back from dark age there are few other themes I've been building for a while (Technic and Modulars). So there was no time and space for trains. Space is still a constrain, but somehow I decided to buy a locomotive from 60052 set simply because it was rather cheap and looks good. Next was an unexpected find that one of BL shops I was buying parts from had few Maersk coloured parts. I thought "cool, I've always wanted to have some of these". Well, you might suspect already how did this end - yes, I've bricklinked the Maersk locomotive (had to substitute some parts, but looks the same). This was a great chance to learn about trains. And at this point I found I could build my own stuff. I've been lurking Train section of EB forums for quite some time to enjoy the quality of MOC's as well as to find solutions for existing issues and learn new stuff. Siemens ER20 CF So let me present you the first MOC - Siemens ER20 CF. This Eurorunner family model is used by Lithuanian Railroads (LG - Lietuvos Geležinkeliai in Lithuanian) with total number of 44 units across the small country. There isn't much details or stories available on the internet apart from Wikipedia article. From my personal perspective ER20 CF looks like a Ferrari amongst other rolling stock built back in USSR. So it was an easy choice for a model. But not from LEGO perspective. Original train is modular and some parts from less powerful and smaller in size ER20 used in ER20 CF. However ER20 CF is longer and higher. The first challenge was cabin, the roof of the cabin actually. Since CF model is higher there was and extention-adapter made for the roof, which gives a unique look and it was the main feature I wanted to make it was built well with LEGO as it makes model recognizable. This gave me a lot of headache as I've experimented with various slopes. Once this was sorted the rest was pretty much straightforward. Well, the front wasn't easy too, and it had to be rebuilt quite a few times, but I knew it is going to workout eventually. My intention is to build a static model, that could go over LEGO train tracks. So no motorisation, at least for now. However the model is 58 stud long (excluding the magnets) and since LEGO track radius is quite small I had to deal with another issue - boogies. Train has 6 axles and it doesn't help. I'm sure this is not a big deal for you guys, but I've spent quite some time trying to figure out the best option for 3-axle boogie. Couldn't decide which is the best so built each of two boogies slightly differently - one is rigid with floating middle axle, and another one has last axle articulated. In the end train looks ridiculous while passing LEGO curved track, but it manage to do so. I'm satisfied with the model, especially since I'never build in such scale before. Obviously due to this there are also few bits I wish to do better (especially motorisation), but haven't got to find the way of doing it. I'm happy to hear your comments and suggestions so I can improve in the future. Few more pictures in Flickr album.

While this option sounds great I doubt it is going to have a great success. TLG had such service years ago and it was expensive. It won't be much cheaper with Bricklink either.

Depends which colour your model is and how big it is in size. Usually, neutral colours like white, shades of grey and black work best. But some other colours might fit well.

@nerdsforprez Some details on batteries/power can be found in fact-sheet: Two batteries in the car are the overall power source: - 1x battery with 80 volts that powers the 1304 Power Function L-motors - LiFePo4 type, 24 Winston cells, 160Ah, max. current limited to 200A - Charging time – 8 hours max - Balancing protection circuit that control the charging and discharging process on each cell But how to connect a L-motor to 80 volts? Per motor pack there are always six motors in series and four string motors in parallels. That creates 24 motors in one chain serial parallel combination. And by adding that up to the total amount of motor packs you get 12 volts per single L motor. - 1x battery with 12 volts (standard car battery) that powers the power steering while also covering the power peaks by the system - DC/DC 80/12V convertor that powers all the LED lights and other electronic functions - DC/DC 80/24V convertor that powers the electro-magnetic clutches

There is another way of picturing both models in one picture. You need to put your MOC on some flat surface on a distance from real train and picture them together. Something like this.

Well, it is not reason to omit rather good (I'm reading being one of the best) rendering options provided by Mecabricks. Your options here would be to chose a different model or contribute your time adding missing parts into Mecabricks library (if possible).

If you have intention to never use PF parts do whatever you want, otherwise no liquids should be in contact. Another advise is not to use dishwasher. Major concern is the hygiene - you never know what LEGO models contain and programs used for cleaning are not hot enough to kill the bacteria. Another concern is the cleanliness - I did not to test it, but keeping in mind the way dishwasher performs it doesn't look to clean the parts well. I'm using washing machine instead.

I think tyres on Stud.io renders are glossy because chosen colour is "brick black" rather than "rubber black".

I've built few modular MOCs myself. I found working of facade to be the most enjoyable. The sad truth is that you will have to spend 2-3 times more bricks (and money, if you are going to buy some) for the rest of the modular than just a facade.

Oh noes... Not yet another MOC to blame for #3 connector scarcity :/

Very impressive model indeed. I'm still discovering features they've used in this model which I like a lot. Particularly the way they cheated here the solution using linear actuators to achieve required distance and connections points for outer shell. Oh and yeah, I'd love to have some of those new coloured parts produced for this model, even if they are not up to usual LEGO specs.

Sorry, I just picked up last post to comment on bending. Didn't want to contradict your statement.

Well, the photo I have is for multi-section boom, but yes it bends.

Wow, it is not just one but three great MOCs. I really like the effort you put into details not just to function but also look great.
