This
is truly one of the smallest gearmotors we've found, and it is top quality.
High
quality all-metal gears with a faster 75.7:1 ratio,
The
entire motor with gears weighs only .3 ounces! They are
rated for
5.0V DC, but we have tested and run them at 9.0V, even up to
12V. Many tires/wheels can be directly mounted to the 3 mm diameter output
shaft.
The 75:1 comes with a
stubby 5mm long shaft, 3mm diameter.
With
these motors we will see a new evolution of tiny bots. YES,
the prop adapter and
aluminum hubs we sell will fit on these motors!
