ZENE

We designed a very nice motorized kit for this set. Using customerized motor, with touch control speed, and showcase it at your preferred speed. Need your comments, friends.

I want to say that the metal differential you wanted to add is from ZENE? but it seems that you forgot to update this part, haha, and the brake disc that comes with the transaxle

The 42143 we use with one motor weighs about 3kg when assembled, the speed can reach more than 50km/hr, and the top speed has reached 60km/hr+. So for your goal I think two motors are enough. Just as mentioned above by @Ryokeen, how to make multiple motors cooperate and distribute power well needs to be considered.

Our motor is connected to a planetary gearbox, which is customized and designed. Reduction gearbox (i) is 1:4

Yes, your reply summarizes it very professionally. It is difficult to solve the problem of using universal joints for front drive and steering. If the front wheels must be used for driving, the u-joint must be cut shorter. This method can solve this problem, but need to try it bit by bit in just a few MM. I think this issue needs further discussion @Krzychups @Ryokeen fyi It's cool, bro, especially since I love formula racing. Looking forward to more demonstrations from you, you may consider sharing some videos on YouTube. (I directly copied and pasted the image here, but I think maybe you have a new account and cannot upload too large images.) Great work. Look forward your sharing. If you can make a manual of this set and I think I will buy it, haha. However, I am a little worried that it will not be strong, and the structure will easily deform, resulting in incomplete gear meshing, and then toothing.

@Lixander I checked the size parameters of your generator's motor, and they don't match our planetary reducer, but the differential and transaxle are not involved in this compatibility issue.

@Krxlion Thank you very much for your liking, bro. Currently, our MOCs used these accessories for LEGO 42096, 42156, and 42143 sets. The previous goal was also to design and modify LEGO cars. For the time being, the focus is still on the LEGO sets RC modification, after all, their design is very good. We have some sports demonstrations of these cars on YouTube. https://www.youtube.com/channel/UCoj1BNklidkrlze8oTlcg4Q @aFrInaTi0n You are definitely a brave and adventurous creator, haha. Thank you for your support and I really appreciate your work. Regarding the design drawings, we have no plans to fully disclose them yet, as we are worried about others using them for commercial purposes. @FriedlS You are very discerning, haha @NoEXIST It is almost indestructible. The previous version encountered very violent operations, causing the nylon material of the connector to melt. However, I later upgraded it to metal, and so far I have not encountered any damage. @Ryokeen Yes, our products now come with 2 output connectors for the user to choose. However, considering the possible waste and cost issues, we will consider letting the customer choose the connector in the future. After seeing the problem you raised, I discussed it with the designer and he told me that he had encountered a similar situation before and that cutting the length of the U-shaped universal joint could completely solve the problem. But I may need more description from you, please send me an email and we can discuss more, if you still need to solve it. @glowytheglowbug We mainly fix the connection of the brushless motor through the holes on the modified planetary reducer. You can refer to my description above. At present, we are connected to the differential, and the differential is connected to the chassis. If you only need the motor and planetary reducer parts, you can consider similar connection and fixing method. If necessary, you can email me your detailed needs, support@zen-estore.com.

I have sorted out some questions about the previously released alloy differentials and RC modifications of brushless motors. I have tried my best to explain the attributes and parameters of the accessories. I also hope to gain everyone's suggestions and try my best to achieve continuous improvement. Update, thanks again in advance for your time here. What motivated us to redesign the LEGO differential? Why is the differential so important to high-performance LEGO sports performance? Here we need to start with some of the problems we encountered. Accuracy issues: LEGO differentials are limited in accuracy due to part manufacturing limitations, which may not be ideal in some applications that require high precision. High-speed toothing problem: Lego materials lack the strength and precision to rotate with high accuracy at high speeds, which results in gear toothing. Load Capacity: LEGO differentials are generally designed for lightweight models, so they may not be suitable for some heavy-duty applications. Friction and Durability: Friction can reduce efficiency, and parts can wear out over time, affecting differential life. Specific Use Restrictions: LEGO differentials are generally of a general purpose design and may not necessarily be suitable for all specific engineering or mechanical applications. Some common questions - Differential part Is the product a complete set or a separate accessory? Answer: Currently we provide two types of products Complete modification package for LEGO Technic 42143, 42156, 42096 Accessories part, a) Independent differential, available in square, H-shaped, single-input, double-input types. Please refer to the figure below for dimensions (compatible with LEGO unit proportions) figure 1 figure 2 figure 3 figure 4 b) Drive axle, alloy 1:10, 23801 & 11950 c) Drive axle, nylon 1:8 23801 d) Small set of differential + motor + planetary reducer + ES + drive axle + metal shaft + universal joint. The motor is a 2445 brushless motor and supports 2S (7.4v), 3S (11.1V) model aircraft batteries. Compatible with "LEGO"/RC output Answer: Yes, there are two ways of output, cross-shaped or square metal output shaft, with U-shaped universal joints with holes on both ends, fully compatible with your Lego. (Many thanks to @FriedlS for the HD shot) figure 5 figure 6 This metal differential gear ratio: Answer: 1.65:1 Does the U-joint have a LEGO shaft hole on one end? What is the difference when used without a U-joint? Or do they accept metal (hexagonal) shafts? Answer: Yes, this universal joint has a lego shaft hole on both sides, just like CaDa's metal universal joints. How deep is the U-joint at the differential input? How far away will the turning point be? Answer: The bending point of the U-shaped universal joint is located outside the differential output, and the shafts can be connected in a consistent manner. The size of the differential can be considered to be the overall size and will not affect other designs of the structure. Why do differentials come in black and white, are they the same? Answer: The material is the same, the only difference is the color. Colors are generally sent randomly. If you have a request, please let me know. Motor and planetary reducer part Does the motor have a housing to attach it to the LEGO part? Answer: Yes, the motor is currently connected to a planetary reducer. The reducer housing has enough holes for fixing to the chassis structure. Refer to the red arrow mark in Figure 7 for fixing to the differential and match the points in Figure 8. The blue latch, the blue arrow in Figure 7 connects to the metal shaft with the middle arrow in Figure 8 for power output. figure 7 figure 8 Not sure what "bearing drive shaft" means, any ideas? Is that the hub? Answer: The general Lego drive axle is a combination of 11950+92909 parts. The bearing drive axle is a combination of 11950+stainless steel specially customized 92909 parts. It has built-in ball bearings, which has better part strength and smaller friction. The service life is increased hundreds of times. (1:10 bearing transaxle cannot be linked with Lego wheels) What is the reduction ratio of the planetary reduction gearbox? Answer: The reduction ratio of the planetary reduction gearbox (i) is 1:4. Since the maximum speed of the matched 2445 motor can reach 50,000 rpm, the maximum speed after deceleration is 12,500 rpm. What are the parameters of the 2445 brushless motor used? Answer: 2445 brushless motor, 3600kv, maximum speed 50000, maximum voltage 13.2v, please refer to Figure 9 below figure 9 Other questions Transaxle rotation resistance problem Answer: There will be some resistance to initial rotation, and after running for a period of time the resistance will reduce to normal ball bearing levels. The parts are all glued/screwed together nicely so the wheels won't come off unless something breaks. What is the remote control and is it sold separately? Answer: The commonly used 2.4G radio remote control RC gun handle and receiver with light control support one-handed operation (controlling direction, acceleration and deceleration). The remote control distance is stable within 400 meters. In addition, the receiver has a built-in gyroscope. , you can manually turn on the gyro mode to assist drift control. If you need to purchase this part separately, please contact us. What model is the battery and is it sold separately? Answer: For general model aircraft lithium batteries, it is recommended to use 2S, which has sufficient power. 3S is a bit violent. There is no sales at the moment, please contact us individually if necessary. About the lights of 42143, 42156, 42096 Answer: This kit comes with special lights that are compatible with the remote control. Some of the lights can be directly controlled manually using the same remote control handle, while other parts are automatically controlled. For example, the taillights will automatically dim and brighten according to the amount of the accelerator.

@hello1322 Thanks for your questions. 1. Yes, all modification accessories.Of course, the Lego itself must be your own😉 2. This super power modification kit comes with special lights that are compatible with the remote control and are directly controlled by the same remote control handle.

Very beautiful structural design, as well as site protection, it looks like you have done very detailed planning. Hope to see more follow-up content. Our differentials are also evolving and we hope to provide more valuable accessories

We have recently further upgraded the differential. The output interface is made of one-piece steel instead of the previous nylon material. I think it is indestructible. https://youtu.be/F37HhdK6dYY?si=6EOQCrpqma9TUqCo For previous verion: Don't worry. The previous version is also very strong. If the interface is damaged, please contact me. My new design takes this replacement into consideration, and I will provide you with replacement accessories and solutions to upgrade it.

First of all, regarding the price issue, I don’t want to discuss it here. I think all of us just want to share some works and ideas here so that everyone has the freedom to choose. I believe friends who have used it will understand our design, materials, services, and free shipping. Since these products of ours are all hand-made and some parts are 3D printed, the specifications and instructions are not provided detailly. The initial production is also to form an RC set. But thank you very much for your suggestions, we will gradually improve the relevant information. In addition, regarding the issue of trust, I think my service tenet is "Don't worry, we will solve it for you." In this regard, we hope to continue long-term cooperation with every friend.

@gyenesvi The white part in the picture above is the differential, which is fixed through the frame and can be connected to the round hole of the motor.

@Ryokeen @wower I thought this conroller was cool enough, hahah, it seems I was wrong. If you have any recommended controller, please tell me and I will try to make some adaptations. Friend, You may be looking at the accessories section. Our BM collection mainly divide into two categories: 1. The BM Kit of 42143, 42156, and 42096 include all modification requirements( Such as differential, remote control, ESC, motor, battery, etc. I think wower posted the list very clearly.), except the LEGO set itself. 2. The other part is the accessories section, mainly related to differentials and wheels and transaxle related. I think you can refer to this for more details: Technics RC (zenelego.com) We still have a lot to improve on how to provide better descriptions and specification for understanding clearly, and hope you can give us some suggestions.
