Nice! that's the game changer for me too!

Thank you for the suggestion. I didn't make myself clear in the first place I guess. By "output" direction, I mean the output axle (the black axle on the most left in the picture above) rotating position when it is idle. In the original design, it is like "X" (diagonal), but I need it to be "+" (upright), that is why I add a blue sliding 20T gear between the 12T bevel and the black 12T. I am currently trying to tune the stepping mechanism to see if I can avoid the sliding 20T here.

Agree that Chinese bricks are much cheaper, and it also have a lot of good designs there. But the biggest problem is the part quality. I have tried some sets and they were so hard to assemble. Considering the effort I put into this MOC, I can't set the price to EUR 15 on RB, otherwise, people will think this one is inferior to other MOCs in the same category. But I don't mind creating a coupon ("11EUROFF") here for whoever wants to build it. Cheers.

Thank you for your honest opinion. What do you think a fair price should be?

Thanks! LEGO parts are a bit too curvy for this, so I have to extend them with beams to make it a bit more flat. Thank you! Thanks! I tried to use the least amount of non-technic bricks because they just don't look right when pairing with technic parts for some reason. Meanwhile, non-technic bricks are easier to fall, and it is risky when driving around the MOC with RC controller. P.S. I just posted this new design at LEGO MOC 1:8 Chevrolet Corvette C7 V2 by Lego__Bee | Rebrickable - Build with LEGO in case you want to check out more pictures of it.

After some time with my Corvette C7 MOC, I decided to upgrade it based on feedback I received. The most significant change is the hood: in the original version, it was a bit "flat," so I redesigned it with curved panels to more closely resemble the real car. Unfortunately, this change meant sacrificing the hood vent, which was a tough trade-off. With the new hood design, I also had to adjust the front lights. After testing different options, I realized the soft axle was the best way to replicate the daytime running lights (DRL). Although I’m not usually a fan of the soft axle, it really enhances the look here. I added a black stripe across the entire body, making the design more stylish and conserving red pieces for future builds. To match the stripe, I also changed the roof to black, which turned out to look even better. Another improvement was to the tail lights, which were somewhat understated in the original design. I pushed them out to make them more noticeable. I also updated the rear wheel arches to mirror the original, giving the car a sportier look, and smoothed out the decklid for a sleeker finish. Finally, I added some custom decals—or, well, stickers. They’re simple but fun, and they add a touch of style that makes the finished model even more eye-catching.

Seems to be a good start for Doge viper.C7 Vette should have lower front hood, but due to the chunky LEGO v8, can't really lower it any more. Thanks! Thank you!

Here is my recent MOC of the Corvette C7, and I'd like to share some details about it. It took me over three months to design, and here's the result. The model can be fully motorized by adding PF parts to the static version, making it easy to swap motors when needed elsewhere. I've included a 4-speed gearbox in the MOC, which works with remote control. Initially, I thought the driving ring part wouldn't be strong enough for motorization, but it proved to be reliable. During testing, the driving ring part neither slipped nor was damaged. Interestingly, I started with two XL motors due to the MOC's weight, but they caused issues. The high torque twisted the axle combining the input from both motors. Switching to two L motors, despite their lower torque, resulted in better performance due to their quicker rotation speed. The differential 65414 effectively converts rotation speed to torque. The paddle shifters are based on the idea from Rotating Paddles - LEGO Technic, Mindstorms, Model Team and Scale Modeling - Eurobricks Forums, with some modifications. The entire gearbox is at the rear of the car, requiring an upright axle for input. To achieve this, I had to use a blue sliding gear to change the output direction. The following picture is for height adjustment, rotating the black 20T gear moves the two pins where the shock absorbers are attached. The front wheel mechanism is similar but more compact. I encountered issues when motorizing the height adjustment, as the medium motor didn't provide enough torque. Down-gearing increased torque but damaged the universal joints along the long axle connecting the front and back. To prevent parts from cracking, I added a 24T gear with a clutch (60c01) to both the front and back. Since I wanted the roof to be removable, the windshield needed to stand independently without roof support. The trapezoidal shape of the windshield was designed with all four sides as integers to build it with beams as below. The top is 18, the bottom is 22, and both sides are 8. Locks on both bottom corners ensure stability when mounted on the car. I used the same geometry for the back trunk cover, extending the sides twice. Here are some pictures of the MOC: Here is a demonstration video: Instructions are available at https://rebrickable.com/mocs/MOC-188766/Lego__Bee/18-chevrolet-corvette-c7, and your comments are appreciated. Thanks!

True, some angle is not easy to achieve, so I have to be creative. I'll try posting more often. Thanks! Thanks! Need to minimize the weight so this big thing can actually run with motor.

It's been a while since my last post, and this time I bring you my most recent MOC, a 1:8 scale Aston Martin Vulcan. The actual size is 58cm long, 24cm wide, and 13cm tall. This MOC is designed to be a combination of a static version and a dynamic version, meaning dynamic parts (motors, lights, and battery) can be directly mounted to the static version and it can run. In order to achieve this, I designed it in a way that the entire body can be completely detached from the frame. This has been a standard for my recent several 1:8 MOCs. Another significant benefit of this design choice is the ease of fixing issues deep down in the frame without needing to break down the whole body. Given that this car has a V12 engine at the front and is a rear-wheel-drive car, the drivetrain from the rear wheels to the engine has to collide with the HOG handler because both of them will go through the central line of the frame. My solution for this is to use a freewheel (in blue) to cross, as depicted in the following picture. I tried my best to reduce the size of the MOC, but it's still very big and very heavy. In order to make it motorized with changing speed, this is the gearbox I came up with. The orange part can slide to change gear ratio between 0.6 (12/20) to 1.67 (20/12). The pink 1x2 thin lift arms will hold it in position. Two buggy motors will be mounted on both sides of the top-most orange 5x7 frame. I have to use a pair of gear to reduce the speed and increase torque for each buggy motor before connecting into the 5x7 frame. I experimented with different pairs, and the only feasible one is still the 12-tooth and the 20-tooth, which can provide enough torque to kick off the car from a stationary state but not too much to grind the gears. Here is a video about how it runs with the high gear. Here is the full feature list of this MOC: Independent suspension on all wheels. A functioning steering wheel and HOG (Hand of God). An openable hood. Doors that swing open with a spring lock. A working V12 engine. Two-speed gearbox. Detachable body from the frame. And here is the RB link for this project LEGO MOC 1:8 Aston Martin Vulcan Static Version by Lego__Bee | Rebrickable - Build with LEGO I hope you enjoy seeing this project come to life as much as I enjoyed building it. Thanks!

Does anyone happen to know where I can find early versions of LDraw all-in-one installer? The recent installer has some issue to generate instructions for my MOC, so I want to revert it back to some old version. Thanks!

Do you mean this by DLR?

Feeling myself very ignorant now. Could you point me out what the LEGO approach for DLR is?

FYI, I just posted the instructions at https://rebrickable.com/mocs/MOC-149456/Lego__Bee/18-lego-technic-ford-gt

I didn't pay too much attention on the actual scale, and the reason I mentioned it 1:8 is because I use the tire of LEGO Lamborghini, and all the scale starts from the width of the wheel arch opening, which in my case is 11. Here is my blueprint reference. Just did my calculation. the width of the real car is 195cm, and the MOC is about 21cm width, so the scale is more like 1:9, so thanks for pointing this out! BTW, I used to build 1:12 cars, so I believe there are also specific challenges for smaller scale MOCs.
