You give it a pulse of 1.7ms, it runs right at 2X speed. Same thing for the other direction? You give it a 1.4ms pulse, it runs left at X speed, pulse it at 1.3ms, and it runs left at 2X speed?
Therefore, the farther the input pulse is from 1.5ms, the faster it will travel in that particular direction?
You got it. They used to sell these with instructions to modify, now they do the modification for you.
Makes really nice rolling gizmos.
