limited quantities at reasonable
prices ($35) from Fingertech

has about 40 of these left. After
that, it appears that they’ll only be
available directly from Maxon,
costing at least $100 each. Even for
an article titled “Ultimate Ant,” that’s
a bit pricey. So, the community has
embarked on a search for a
replacement that will satisfy the
almost cult-like love of these tough
performers. Pololu 35:1 or Banebots
24:1 were suggested replacements
by a few of our experts. It appears
that this category is usually going to
be driven by the surplus market,
where high quality and reasonable
price provide best value.

The Fingertech Robotics Tiny ESC and

run-off — or perhaps a meeting in the box!
Four votes for Fingertech Tiny

One vote each for three other kinds.
This sure sounds like a tie.
