Quoting the ant
sorry i don't know how much 4 Ncm but what if i added it to a model the size of Nicjasnos Mustang?
This car is not bigger or heavier than muy porsche, and it should work fine.
4Ncm is for exemple a M motor torque(not power), 2 RC motors joint torque in the internal output, or XL motor with 1:3 external ratio... choose your motors ;)
Wow! I am truly amazed that this could be done with LEGO! Our MINI Cooper has a CVT and it is really fun to drive. Only criticism I have is that the music in the video detracts from the quality of this amazing piece of engineering, as I would have liked to better hear the mechanism working at different speeds.
