Looks far much better, than 42109.

It would be good to see it side by side with 42074

I used the masonry profile brick (98283) instead of the grooved one. Exists in sand green, available in quantity, cheap and in my opinion looks better than the grooved brick.

Absolute hit. The exterior is great, and I don't care much about the interior. I skipped the last two modulars, but this one is a must buy.

I cannot do a 3D plot, however I think my original colored charts were a kind of 3D plots. But I made these six comparisions, but I have no idea what we can learn from them. Prices are adjusted with US inflation data, and 2019 equivalent prices are displayed. I'm not really sure about the method to use US inflation, because the manufacturing is in the EU, so it would probably be better to use some kind of EU inflation (?) and EUR/USD conversion rates. But it should not be too different. The orange spots are the sets with Power Functions. My original charts told me more, I cannot see the added value from these ones. I think I will not create more charts. Let's discuss these ones.

I have all the data required for these graphs (except inflation correction). But it took me about 6 hours to collect the data, draw the graphs and analyze them. So it's quite time consuming, but I will try to make them later. 8275 released in 2007, so it is included in the data. I went back to 2005, because that was the time when TLG migrated to the new beam/liftarm design, and the darkest year with only 5 sets released. Definitely many things changed at that time. I already have the colored data for PF, pneumatics, long linear actuators and pullback motors. Every pullback sets are 20 USD RRP, no exception. If a set contains pneumatics, then both PPG and PPP are in the trend line, only exception is the 42080 with the new pneumatics +PF. Only heavily motorized and licensed sets can jump out, and thats why I only posted the colored PF chart. And marked the Porsche and the Bugatti. I think the licese fee is about 15% of these sets.

It is the flagship set 8285 Tow Truck from 2006. It has big wheels, metalized parts and pneumatics, and these do not reflected at all in the price. Only PF increases the price, and only when there is more than a battery box and an M motor is present in the set. I think there is no physical or economical reason, why a log would fit better. A logarithmic curve bends down much faster than our data points. Anyway I tried, and it fit worse. A log vs. log fit tells nothing new, just compressing the upper segments, and it is harder to see, that big sets are cheaper. Any slowly bending curve could fit better, but there are too few data points in the upper segment. I would simply propose to use two linear fits, with a break point around 2000-2300g. It will work fine. What we actually see here (I think) is the "volume" pricing. The price of a set is composed from volume related (like weight of plastic, longer instruction, etc.) and fixed costs (like box design, standard process of accepting a set design(kid proof?, using bricks currently in production? etc.). And some others in between, like the number of lots described by @nerdsforprez... The fixed costs increasing the price of a small set faster, than a big set. On the other hand small sets are selling faster, than big sets, so the fixed costs are distributed better. What I want to say, there is no way to tell the exact shape of the curve. Maybe TLG could, but we have no chance. Therefor a simple broken line is good enough. True, I'm correcting it. It is 42070, I confused weight with piece count when manually marked the point.

OK, I made these graphs to check the PPP vs. PPG, because I like to visualize things, I underastand things better in this way. I used the same sources as @nerdsforprez, USD RRP prices are from Brickset, weights are from Bricklink. Weights are containing box and instructions too, but it would be too much work to calculate the net weight. On the other hand, all sets have box and instructions, and bigger sets have bigger box and lomger instructions. So I think weights are still proportional. First the price vs piece: I checked several special elements, like the long linear actuators, the pullback motors, the pneumatics and the Power Functions in the sets. I found, that only PF counts significantly in the price. The PPP scatters a lot, but only the PF sets pops out. Then, the price vs. weight: The graph is much more clear. What we can see? (42099 is not included in the graph, because there is no weight data available) Inflation: 25-30% price increase is visible over the 15 years. Big sets are cheaper. Only several overpriced sets. All heavily motorized, or licensed. I think Porsche is also overpriced compared to big sets.

Thanks you like it. One more people faved it on flickr, and I also like it, So we four together are already a little crowd.

I always liked the shape of the otherwise old 8081 set, and when I decided to create my first RC car, I selected this set to mod. Of course, an offroader must be 4x4, and to speed up the development I used the 4x4 mod by @Thirdwigg, see it there: https://thirdwigg.com/2012/04/26/4x4-8081/ I added a 2 speed gearbox with the new orange selector, and used the HOG steering gear on the top of the original 8081 to switch gears. Then I added my RC solution with x2 L-motors, steering by servo, and used the CADA battery box for remote controlling. Finally I reshaped and recolored the body and the chassis, and upgraded the interior. Well, after writing the list of mods, I realized that only a part of the body survived without modifications. But the mod is still a recognizable 8081. I'm not really happy with the performance of the offroader, because the chassis is too weak around the L-motors, and the power of the two motors disassembles some pins in the chassis, and the driving gears start to jump. I failed to find an easy correction, the whole middle part of the chassis should be redesigned, so I abandoned this project, and started a new, bigger and better offroader, based on the experience from this first RC model. But I decided to post this mod here, anyway. Some more pics here: https://www.flickr.com/photos/138715943@N07/albums/72157709895583186/with/48379303261/

Extremely well made. I recognized it immediately.

Something like the 21309 Saturn V? Or even larger?

Today afternoon I noticed, that Bricks & Pieces does not ship to Hungary anymore. Only US, UK, Germany and Switzerland are supported. B&P was the best way to buy the rare and expensive bricks, which cost a little fortune on BrickLink and elsewhere. PaB is not comparable with B&P, this is a real loss. Why does TLG stop selling individual pieces? Anyone know details? Will we get it back later?

The tentacles side is the front. There is the cockpit with 4 seats for the minifigs and many control instruments. And thanks for everyone who comments and likes this creation.

I add this rendered image, and enter the spaceship to the race.
