franciscok Posted January 30, 2016 Posted January 30, 2016 (edited) In the german Porsche Site, the GT3 RS is always dark orange, is this the most emblematic color for the 2016 GT3 RS? Also isn't the spoiler fixed? If so one less functionality if they keep it real... By the way a seven gear PDK gearbox is the only available option for this model.

Victor Imaginator Posted January 30, 2016 Posted January 30, 2016 I'm still hoping for RC. TLG released RC flagship every 2nd year before.
JohnBS Posted January 30, 2016 Posted January 30, 2016 A couple of points occur to me:- First, price. I think that the best information we have is that the finished model will be in Lava Orange (great from my point of view). If so, all the visible bits will be in a new colour for Lego so that would explain a higher unit price per part. Second, RC. If drive and steering are to be RC (my preferred scenario) the centre red shifter must be something that isolates the gearbox from the power train. This would permit vrooming with the flappy paddles. As many have said, to try and drive this size vehicle through even a 4-speed gearbox would be impossible, whatever motors were used. However, a direct drive (not through the gearbox) from coupled XL or L motors would then be a practical option. What do you think? John
allanp Posted January 30, 2016 Posted January 30, 2016 (edited) I don't think making parts in new colours is enough reason to jack up the price more than 2%. It would be inefficient to drive the car through a gearbox using the currently available gearbox parts. A lot of power is wasted through friction. But if they have made new parts then it could be done very well and efficiently. Also, if this car is to be two wheel drive and with a realistic drive train (not having any gear reduction after the diff) I think a new diff will also be needed. Parts like these would greatly improve the performance and reliability of the car and many future sets to come. having many new parts could be one of many reasons for the high price.

AlphaX Posted January 30, 2016 Posted January 30, 2016 (edited) I doubt that it will be RC driven, its performance would be shite to say the least, and why would you want to have only RC functions but no RC drive. The only thing i see confirmed are the Powerfunction Lights. http://www.porsche.c...911/911-gt3-rs/ looking at this and its features and thinking about which could be implemented in a set like this. I believe recreating something like Porsche Doppelkupplungs Getriebe (PDK) would be a must have, and would be possible, for a set like this to me. The real Car does have 7 Gears, adding these would also be astonishing. http://www.porsche.c...and-rear-axles/ The car also does have a "Liftsystem" that makes the ground clearance adjustable. That could be something that transists very well into lego and also has been done before. (And would be done via Power Functions. http://www.porsche.com/germany/models/911/911-gt3-rs/chassis/rear-axle-steering/ The rear axle steering is also something that could be easily added. (Maybe the rod that goes from under the steering wheel to the back of the car is connected to it?) Edited January 30, 2016 by AlphaX

(Maybe the rod that goes from under the steering wheel to the back of the car is connected to it?) I think you are complete right about this, I forgot that this car has 4 wheel steering in real life. My mock up confirms this, the links I assumed where for the gearbox end up so close to the rear suspension, that it would not make sense to link them to a gearbox. This would also explain the axle with CV joints going to the steering console and why the left and right links are so far apart. In my opinion, the sequential gearbox will be routed through the central tunnel, just as in the real deal. This really is a reincarnation of the 8880. (the purple parts in the image below are placeholders or temporary supporting structures) EDIT: a small update: Edited January 30, 2016 by Cumulonimbus
franciscok Posted January 30, 2016 Posted January 30, 2016 http://www.porsche.c...-axle-steering/ The rear axle steering is also something that could be easily added. (Maybe the rod that goes from under the steering wheel to the back of the car is connected to it?) I'm not so sure if this could be so easy. It's no exactly like the front steering wheels. The rear wheels only slightly turn, and at low speeds in opposite direction of the front wheels and at high speeds in the same direction. It would be a very dificult exercise to replicate in legos, especially a feature that is speed dependent. But that's just my opinion!
Jeroen Ottens Posted January 30, 2016 Posted January 30, 2016 Looking at the picture in this post: http://www.eurobricks.com/forum/index.php?showtopic=120399&st=325#entry2452751 I don't think there will be rear wheel steering. You can clearly see a double crossblock, which makes perfect sense with fixed rear wheels.

I doubt that the steering linkages are connected to the rear wheel steering, as they have a 90 offset. My best guess if it has rear wheel steering would be something to do with the center driving ring catch. As I see no way that the cv joints can be linked to the steering in the front steering collumn. The driving ring catch is in line with the front shaft. Edited January 30, 2016 by Tommy Styrvoky
Gunman Posted January 30, 2016 Posted January 30, 2016 I think that the best information we have is that the finished model will be in Lava Orange (great from my point of view). Anyone confirmed this?
nicjasno Posted January 30, 2016 Posted January 30, 2016 (edited) Orange would be great. I just hope the rear suspension is a bit more sophisticated than that. Also, that diff idea is great. and a 3L bar connects the small gears, and acts like a LSD with some friction. Edited January 30, 2016 by nicjasno

But there would be a essential feature of the car missing if it doesn't have it.
tibivi Posted January 30, 2016 Posted January 30, 2016 I think i also read that the car was going to be orange, in the auto bild article if i remember correctly I also hope it won't have rc, just some awesome new mechanisms
allanp Posted January 30, 2016 Posted January 30, 2016 (edited) Thanks Nicjasno Not sure what you mean by the 3L bar. In normal operation a 4M axle would be used and those 12t bevels in the picture have a circular hole and a boss, like in this older sketch: For a limited slip diff my idea was to wedge those small white drive belts in between the 20t bevels and the diff case. Put one for a little friction, put one on both 20t bevels for more friction. Edited January 30, 2016 by allanp
nicjasno Posted January 30, 2016 Posted January 30, 2016 If you use normal (existing) 12t thin bevel gears in combination with the axle hole on the diff, you put a bar through them (think: lightsaber bar) and you get a lsd.

You can clearly see a double crossblock, which makes perfect sense with fixed rear wheels. Ah, I missed that picture ... Yes, that make rear wheel steer less likely (unfortunately). Meanwhile, I made a space claim for the engine compartment. This marks the maximum available room for the rear axle, gearbox, motor, and possible PF elements. The fact that you can stack a boxer engine op top of a BB with plenty of room to spare, gives an idea of the size:

John With double shocks in the rear, it must be supporting the added weight of a battery box and motors. As for being too large for RC, I disagree. My unimog has tons of power with a single XL motor. 2 L motors would be plenty for power and speed for this Porsche. It's still a Lego model, they wouldn't gear it to be too fast or it would shatter if it hits a wall. My guess: RC drive, steer, transmission, suspension up and down, using two remotes like 8043. Using PF2?
AOW Posted January 30, 2016 Posted January 30, 2016 Cumulonimbus remember that is it Boxer 6 not flat V-6 (180 degrease) engine. The Ferrarri Testarossa had V-12(flat 180) :)So probably the engine will take more space :)
deehtha Posted January 30, 2016 Posted January 30, 2016 TLG put a lot of detail in this, but I suspect they made it a flat 6 and not a boxer 6. It would add a lot of pieces for an effect most people would not even notice.
Cumulonimbus Posted January 30, 2016 Posted January 30, 2016 Update: I think that's it for me. My aim was to get an understanding of the mechanisms, but the inner workings are too covered up to do any estimated guesses. I have become even more curious about this model, hardly can't wait to find out more about the model accuracy, the design choices, mechanisms, new parts, etc.

I have become even more curious about this model, hardly can't wait to find out more about the model accuracy, the design choices, mechanisms, new parts, etc. Looks good so far, maybe more information can be obtained from the video, I found it helpful to put the video in full screen and play it at .25% of the speed, then I took screenshots of areas of interest. I Think If you messed around with the placement of the center "shifter" that could hint to how it's connected to the rear transmission.
anothergol Posted January 31, 2016 Posted January 31, 2016 Is looks amazing, but one problem I see is that Technic panels all show ugly sprue marks & are to be covered by stickers. So if it ends up all black, it's gonna be chockful of sprue marks, no?
