Agreed. I've had few flex springs 'unscrew' out of the white axles. The fix I found was to use them in situations that spin only in ONE direction. Though. that tends to be difficult to do.

Simply mind boggling. This ranks very high up there, along with some of Akiyuki's GBCs and PG52's spirographe. Now, without going much into the math behind fractals, the drawing is made up of a sequence of left/right/left/right turns of 90/180/270 degrees. The sequence is such that the curve never intersects itself ...

Those of us who've been with Technic for a while, did notice that some basic/common parts have seen their colors change 'permanently'. Those that immediately come to mind are below. Old colors are in the top row, and new colors are in the bottom row. There are few others of course. My question is, does anyone know (for sure) what the reason behind the color change? I thought I read somewhere that TLG introduced either new plastics or new molds, and they wanted to make sure the parts are easily 'distinguishable'.

Nice but, isn't the chain on the 'wrong' side of the bike?

I'm a bit surprised no one has used the part below 57702 in any GBC. It sounds VERY promising, and there seems to be few available on BL.

Not sure, in this modern day and age, what British really means. Isn't Mini a division of BMW? :laugh: That also reminds me of the Oil Giant BP ... that used to stand fro British Petroleum, but now, recent US commercials (in the wake of the Gulf disatster), BP is translated into others such as: Beyond Petroleum and Better Petroleum. Unless it's only a PR stint.

A technic set that had no moving parts whatsoever? ... I might buy it if it had a nice collection of connectors, liftarms, and other rare parts. This reminds me of an 'off' joke a professor of mine once told (to an audience of graduate students). Mechanical Engineers worry about only one thing: That the dynamic mechanisms they've built keep on moving and working forever Civil Engineers worry about only one thing: That the stationary structures they've erected remain static/still for many years Chemical Engineers worry about only one thing: Make sure you wash your hands BEFORE you go the bathroom ... Well, the reason I wrote this is: Are you thinking of an Architecture Set built only with technic pieces?

Yes you can. If you take 4 of the short racks and stack them against each other, they're the same length as the long rack. Of course, you'd need to connect the 4 short racks to an 1×16 thin plate, and that'll make the assembly thicker.

My mistake then. If this is your first GBC, then by all means please go for it. The cup-to-cup is one of the first GBCs of Akiyuki's I've replicated. I thought the mechanism was 'simpler' than others, but that's only me. Of course, I did not do any of the fancy 'architectural/styling' work around that mechanism. As for the Doktor-Brick site, the last time I checked, they did not have the cup-to-cup GBC, but they have many others from Akiyuki. Unlike how it was 'interpreted' by others, my original post was not meant to discourage you from such endeavor. On the contrary, I was merely suggesting a different approach (from my own experience). In any event, whatever you chose to do, I'm sure you'll have fun with it. All the Best, JB

@Blakbird: You and I may be saying the same thing. From experiments I conducted myself, I thought the clasping /grip between hose/connector was the weakest link. What I did was simply this: keep on pushing air inside the piston with a hand pump (while holding the piston firmly halfway through stroke) until hoses pop-off. If the seal inside were the weakest link, I'd expect to hear some whistling sound (when air bypasses the seal) BEFORE the hose pops off. Then again, all of this depends on how old the tubing is and on whether the hoses were put on dry or wetted (with saliva?) ... for ease of insertion.

One question that just popped-up: Why are all supercars either for young guys or empty nesters (i.e. have only 2 seats)? Anyone gave this a thought?

I must have mis-read the description. I thought the prize amount was limited to $20 only. Isn't it?

Good catch, and I should have been more careful in my wording. The max flow rate through a pneumatic line is controlled by the smallest cross section (as you said, of course). In this case, I meant the ID (internal diameter) of the cylinder's connectors. I believe I saw a video where LPE_power shows how he drills the connectors, but can't find it now. I like this. We 'bitched' so much about Lego not having LA's ... we got them, and now we're moving back to full pneumatics. I'd love to see a remake of 8455 (or other construction machine) with a LARGE number of cylinders. One can only dream (and wait).

The generosity of some people on this forum! Who can refuse a free lego? I'll refrain and let locals give it a try ... as shipping to the US will indoubtedly exceed the value of the set.

There we go again, another one who simply can't read english. Did you READ my opening line? Doh, lighten up, and grow some skin! But, then again, you must be a teenager going through hormonal changes .... :wink: :wink:

I applaud the initiative and effort. However, if I may be 'candid', that contraption is one of the easiest to replicate. If you want to spend several hours reversing a GBC, try something a bit more 'elaborate', and many more will be appreciative of your efforts. Also, on a sister forum (doktor-brick), some members have already replicated many of akiyuki's marvels.

I think so. Remember that the max force is the product of max pressure times cross section area (Force = Pressure × Area). Since the max pressure is lmited by the 'casping' power of the hoses onto the plastic connections, it 'makes sense' that the max lifting force will not change much. The only way to increase lifting/pushing force is to increase the cross section, or using a tighter plastic-to-rubber connection. One thing I did not see in the review is whether the cross section of the cylinder's connections are the same as before. That determines how fast you can retract/expand the cylinder. In the LPE pneumatic engines, the cyliders had to be 're-drilled' to ease the air flow. That re-drilling makes the cylinders more fragile as the plastic 'wall-thickness' gets smaller, as if those bits are not already fragile to begin with.

Simply Stunning!!! Don't forget the very smooth/feminine 'curves' too ;)

Thank you for sharing, and a very inspirational read. I've always said that there are few 'very gifted' amongst us, and the rest are simply tagging along ... All the Very Best. JB

No biggie, and we all have our days. This was a healthy discussion nonetheless, and some of us are more passionate than others ... passionate because this hobby means so much to us. All the best, JB

Very nice. It would help potential backers to see a side-by-side comparison of this versus other BT solutions out there (Sbrick, SmartBrick, ...). The 'features' I'd like to see compared are: 1. Cost (of course) 2. Compatibility with both iOS and ANdroid 3. Max number of channels 4. ...

Again, this was not bitching about Lego nor was it about what makes sense from a business point of view. We're all professional/mature individuals and need not fall into this non-sense. I was not asking why Lego built 'wrong' models, I do know why. I was merely asking what the community has noticed in terms of departures from real-life. To you this is just another empty thread, so be it. I respect your opinion, but keep in mind that it is the lack of real features that pushed many to build more 'realistic' MOCs ... be it the transverse car engine or the many sequential gearboxes out-there. Once you know there is a gap, you can go and MOC it. **peace** Kudos, that's exactly the point. Though, I'm not sure I agree with you when you say we ALL know the inaccuracies. How many on here know of the intricacies of hydraulics in a telehandler? How many have operated a motor-grader and got to 'appreciate' the many functions and degrees-of-freedom it has? While 'weak' by some standards, to me, the best rendition ever was the 8455 back-hoe, both in functions and realism ... but I'm digressing.

Thank you, you understood (and clarified) exactly what I was after. Cheers.

lol ... that is true, There was in error while I edited the link ... How about this?
