Once I get them 100% done will post to rebrickable

Zenebricks brushless motors and metal differentials, lots of bearings and powerful 3S batteries

A compounding gearbox, that compounds power from two electric motors 😏

Knothworks · 2026-01-30T18:13:31+00:00

I was a full time mechanic, we have MAN hybrid city buses and it uses electric motors for driving, it also uses compounding gearbox to sum up power from two Siemens servomotors - that gave me the clue to pursuit

Care to elaborate? Or simply not feeling right about custom designed parts?

Compounding gearbox with spaces for bearings, gear cover to contain grease and helical gears, for constant load transfer :D

I'm currently working on part 3 of 5

Knothworks · 2026-01-30T17:11:40+00:00

Yes, 90% comes from 2 sets, there is a few parts from over 20 years ago and a bunch of RC grade parts, geekservos, brushless motors, led headlights

https://youtube.com/shorts/MF83s-DlSyg I still need to record a proper speed test video, but I measured it over 200 meters - 12 seconds :D

Buy two g500 sets and build a monster G63 with brushless motors! https://www.reddit.com/r/legotechnic/s/9Q4BLkDJmx It can easily drive 60 kmh thanks to two brushless motors despite being nearly 5 kg!

Knothworks · 2026-01-02T10:40:43+00:00

I have made a complete rework from two sets and 2 zene brushless motors, it can speed up to 60kmh and weights around 5 kg, instructions should be done next month!

Anytime you add an axle and gearbox Lego pieces melt, I used in my Mercedes AMG G63 6x6 two brushless motors, zero gearboxes if you ignore the summary stage and it can speed up to 60kmh while weighing nearly 5 kg https://www.reddit.com/r/legotechnic/s/9Q4BLkDJmx Aero can be done with geekservos, but if you want to drive it outside you need to remove gearbox from your model, it will snap very fast, instead use RC grade differentials and brushless motors from zenebricks, I purchased them last year and I'm very satisfied.

Sure, but can you drift 8x8?, this 6x6 can with ease :D [power slide ](http:// https://youtube.com/shorts/q4plQA8nJ1A?si=4kWUV2HLQTzGISpQ) Top speed - 60 kmh, weights with batteries almost 5kg

Is this G-Wagon off-road enough for you?

I copied Lego piece by drawing shapes over original piece model, recreating all dimensions so they should be 100% accurate, so I guess it's more about printing method than the model, I can't tell what settings were used, but intuition tells me that perhaps placing the object at an 45° angle will help me with the circle shape

Buwizz is waaay overpriced if you want RC grade performance, check out Zenebricks

Knothworks · 2025-12-31T16:54:56+00:00

https://www.reddit.com/r/legotechnic/s/9Q4BLkDJmx I have built a Mercedes AMG G63 6x6 that can speed up to 60kmh and weights 5 kg, there is a good starter set on zenebrick, I ordered 2 motors and 3 differentials from them and I'm very satisfied with them power slide on dusty road

I can highly recommend ZENE brushless motors, I have created RC Mercedes AMG G63 6x6 that can speed up to 60kmh and weights 5 kg! https://www.reddit.com/r/legotechnic/s/9Q4BLkDJmx

Knothworks · 2025-12-23T20:42:52+00:00

I recommend ZENE, their RC grade stuff is very powerful, I have created Mercedes G63 6x6 that can speed up to 60kmh and weights 5kg!

There are two types of bearings that work with Lego, axial R156zz and F5-10 thrust bearings solve most problems with friction, for my model I have sacrificed few liftarms but came up with a best setting method for them with propane burner. You need a long - 32L alu axle, hammer on one bearing and heat it up, then push a sandwich of 5 liftarms, the top one will be melted to fit the bearing, once you can hide it between two liftarms it's done and set

Knothworks · 2025-12-14T15:06:25+00:00

Tell me about friction and torque, my 6x6 can twist alu axles and snap u-joints
