[Rcmower] motor controllers

[Chris]

Howdy guys, glad to find your list from the makers local.  I am also
planning and currently expediting parts for my similar (almost identical
project) RC mower.  If you didn't know already head over to BAM or B&N and
get the current version of Make magazine as there is one on the cover and
the build is from another guy in the Birmingham area.  Also as you well know
there are lots of builds on youtube.

I myself have two of these that 500 watt Izip/Currie/clone electric scooter
wheel and motor assemblies that I want to use on my own.  I'd love to go
with the sidewinder but at $400 its a little steep.  Hope to try it out with
dimension engineering's Sabertooth dual 25A motor driver so I can do tank
like steering and was wondering what your though process was for selecting
your current controller (pun intended)...

Here are my drive motors:

Hope to build the chassis with wood and deck screws and an old gas push
mower then get to the final design that will be built with metal and a 24v
electric motor setup.  I hope to use two interstate deep cycle batteries and
later would love to integrate an arudino to either completely replace the RC
or just augment autonomous function of the mower inside a dog fence.

Cheers,
Chris
