move5 Posted August 7, 2017 (edited) Current status: 8+N+R gearbox, D-N-R shifter, and the engine done. Also some color matchings and a little bit of interior --------------------------------------------------------------------------------------------------------------------------------------------------------- Hello, everyone. Today, I would like to introduce my new moc in progress (and the first to post here). It's Mercedes AMG GT R. (in 1:8, with porsche wheels&Tires) (From https://www.autoevolution.com/news/black-mercedes-amg-gt-r-does-insane-nurburgring-passes-110677.html) I'm planning to make it in black, as 3x11 curved black panels are available now. If amg gtr convertible model comes out, I want to try the convertible mechanism, too. My current status is only up to the drivetrain (engine&gearbox) And this is it. It's a 8 speed gearbox, with D-N-R which I built by myself. At first, I was goint to use charbel's 8 speed gearbox, which is awesome, but soon found out that the gear ratios aren't realistic (the last gear is 45 times faster than the first gear.) This gearbox is also combination of a common 4 speed gearbox and 2 speed gearbox, but different in the fact that the 2 speed gearbox is shifted every 90 degrees, and the 4speed gearbox is shifted every 180 degrees. And that resulted in a realitic gear ratio... in which the last gear is 6.25 times faster than the first gear. The hardest part was the mechanism to make one shift in the 4 speed gearbox while the paddel shift (which is not built yet) is shifted twice. The mechanism is here: Here's the sifting video: Under the chassis, you can see the D-N-R selector, which the gearstick to shift it is not built yet. As I only have times on Sunday afternoons, the progress will be very slow, but I will finish it sometime, so don't be angry even if the progress is slow. Comments are welcome, and advices are also welcome. Thanks. Oh, I missed some explanations on the gearbox. The 4 speed gearbox is just the regular one, with 1:1 to 1:5, and the 2 speed gearbox is 1:1 to 1:1.25 which doesn't work yet as currently I don't have any chains. The chains are also linked to reverse gear. Edited August 17, 2017 by move5 wrote the scale and changed gtr into gt r Share this post Link to post Share on other sites
JDL1967 Posted August 7, 2017 I would like to see the end result. So far it looks promising.. Share this post Link to post Share on other sites
1gor Posted August 7, 2017 Gearbox idea is not bad at all, but keep in mind that Mercedes has only one reverse gear Share this post Link to post Share on other sites

BrickbyBrickTechnic Posted August 7, 2017 Very promising WIP! The gearbox is super advanced and super cool! Wish you luck And of course, I am following! Share this post Link to post Share on other sites
move5 Posted August 7, 2017 Thanks @I_Igor, @BrickbyBrickTechnic. This Sunday, I will be working on DNR gear selector and the paddle shift. Share this post Link to post Share on other sites

Aleh Posted August 8, 2017 (edited) Mercedes AMG GTR does not exist, the car you are building is a Mercedes -Benz AMG GT, or there is a racing mod, called AMG GT R, not GTR like other manufactures Edited August 8, 2017 by Aleh Share this post Link to post Share on other sites

It is also mention on the mercedes homepage. https://www.mercedes-benz.com/en/mercedes-benz/vehicles/passenger-cars/amg-gt/ FYI, the mercedes made 2018 amg gtr's first debut at 2016 goodwood festival of speed, and amg gtr black series & roadster is soon coming out. So, the amg gt family members will be: amg gt, amg gt roadster, amg gtc roadster, amg gtc edition 50, amg gtr, amg gtr, amg gtr black series, amg gtr roadster. Please leave comments if anything is wrong Edited August 8, 2017 by move5 Share this post Link to post Share on other sites
Aleh Posted August 8, 2017 (edited) @move5 At the homepage you placed car called Mercedes AMG GT R (there is a space between GT and R letters). Please do not confuse with the classic CLK GTR. For me as for Merdedes fan this is important. BTW would you be so kind to think about build the monstrous The Black Series Editiion? I will look through the topic carefully aftrwork today. and you forgot about amg gt4 Edited August 8, 2017 by Aleh Share this post Link to post Share on other sites
move5 Posted August 8, 2017 @Aleh I'm so sorry for mis-reading your comment. I didn't see that you said it is gt r not gtr. I didn't notice I wasn't using a correct name at all until now! Thanks for your correction, and I will change them asap. 6 hours ago, Aleh said: and you forgot about amg gt4 Yes I did! Thanks! 6 hours ago, Aleh said: BTW would you be so kind to think about build the monstrous The Black Series Editiion? Yes, as soon as it appears officially, I'll then consider changing it into the black series or even the roadster model. Thanks again for your comment Share this post Link to post Share on other sites

move5 Posted August 9, 2017 (edited) @AkiyamaWataru @Aleh You both are right. I missed both gt3 and gt s. BTW, that's not the point of this topic Edited August 10, 2017 by move5 Share this post Link to post Share on other sites
AkiyamaWataru Posted August 9, 2017 Sorry for ot Looking good so far. Am I seeing this right. You want to use a Geneva mechanism to control the gearbox? Share this post Link to post Share on other sites
move5 Posted August 9, 2017 (edited) @AkiyamaWataru No, it's not a geneva mechanism. (I guess so) It's just making a 90°turn by rotating a liftarm (in larger radius) with a pin around the technic knob wheel. Or is it? I'm not very familiar with geneva mechanism, so maybe it is different from what I saw in a video on it, but still a geneva mech?

move5 Posted August 14, 2017 A little progress yesterday... (some color-matching, some interior, d-n-r shifter, a new fake engine) First of all, I changed the original fake engine into a smaller one, for shortening the chassis, and finally the inteior and D-N-R shifter is in the right place: Some color-matching (or what should I call it?)- interior and exterior will be all in black, and any place else will be in LBG. And rearrangement done on the parts around the gearbox. Lastly the D-N-R shifter: Next, I'm going to work on the paddle shift, which I have an idea about.

Alex Ilea Posted August 14, 2017 Nice work. Is that @brunojj1's mini V8? Share this post Link to post Share on other sites
move5 Posted August 14, 2017 (edited) @IA creations it is similar, though there's difference in the fact that he used technic cams, while I used simple 1x2 liftarms. Edited August 14, 2017 by move5 Share this post Link to post Share on other sites
Aventador2004 Posted August 14, 2017 I am a little confused, are the angled black liftarms the center console? Share this post Link to post Share on other sites
move5 Posted August 14, 2017 @Aventador2004 you are right, but it's still a prototype. Share this post Link to post Share on other sites
move5 Posted August 14, 2017 @LvdH You are right, in the video it takes a lot of force, however, the force that I took was for keeping the liftarm behind the selector in the right place, not the selector itself. It will be okay if I add some reinforcements after on behind it. If it still takes a lot of force with aome reinforcements, I will change it to a smoother one.
