Wave Of Mutilation —
Ultimate Beetle —
lives up to its name.
Axi is the undisputed
champ of high end

MarketPlace was the

The B16 from Robot Marketplace
seems to be the one ($32 each).
One top builder recommends
swapping the stock motors with
BaneBots HS180s ($3 each), a fairly
minor modification. The up side is
much more torque; the down side is
that the BaneBots motors are only
rated to eight volts, so running
them with a 3S LiPoly pack ( 11.1
volts) might cause some failures.
Of course, at $3 a pop, the HS180s
could be changed every couple
are several other
choices including my
and different types from
the Robot Marketplace,
but I’m coming around
to the builder’s choice,
after three articles.
Why? Because both
Dave’s and BaneBots fit
inside the wheel, while
others scab on the
ouside, adding width.
And, width = weight.

on the desired speed/torque and
geometry of the bot, but around

Three different ESCs were
submitted: the BaneBots 3-9 ($58 a
pair); Sabertooth 5 ($60); and the
Scorpion XL ($120). All three will
do the job using two B-16s, which
stall at 2.1 amps. Not having any
personal experience with any of
these, but based on specs, the
BaneBots are a bit closer to the limit
than I’d like (although they do offer
a five amp version for $93 a pair).
The Scorpion is oversized for this
app, at 12. 5 amps continuous. So,
I’d probably opt for the Sabertooth
as the “best value” option. (Prices
are from the BaneBots and Robot
Every vote cast was for a LiPoly,
of around 1,300 mAh, 3S size. This
will range in price from a Rhino
brand at Hobby City ($20) www.
hobbycity.com; to a Thunderpower
at Robot Marketplace ($45).
Our builders suggested a
generic, Chinese, 28 mm or 36 mm
brushless, inrunner or outrunner. For
more money — and some would say
higher quality — an Axi 2808 to
2820 is suggested. The Turnigy
brand will run $18 to $25, where
