Hi Everyone!
I just created this, and thought I would share, as it might give someone an idea for a us in a Moc or something.
I'm thinking a car perhaps with seats on top. It could only be 3 studs high.
It basically gears around the stationary motors and I'm guessing creates the following ratios.
1 motor equals 4:1
2 motors equals 2:1
3 motors equals 4:3
And 4 motors equal 1:1 output.
Now if you could create a level on the remotes that engages 1 channel at a time, you would have silky smooth gear changes!
Sorry if this has been done before!
