  • I believe that the 140rpm is actually output shaft RPM. A few pieces of evidence supporting this are: the Mini Metal 24:1 motor has a higher listed RPM and has the same internal motor connected to a different set of gears. Also, 1.4 RPM is extremely slow and would not support applications in hobby robots (which is what I believe this is target towards).

No public wish lists :(
