My bad. I did a quick search for mixing circuits and found the
venerable (but high priced) IMX-1. Glad to see cheaper options exist.
I've always relied on my own mixing circuits, which cost much, much more
even if only the minimum wage applies ;-)
I wholeheartedly agree with Steve's statement that a more modular
solution (that doesn't significantly increase the number of wires in the
system) is a big win from a maintenance standpoint. We've been
searching over the years for a well-made, reasonably-priced, single
channel controller with an RC interface and the Talon SR appears to be
the winner in that category. Made in the USA is nice too.
Now, we just need to abuse the Talon for many hours while battling to
see how it holds up. Few RC competitions draw large currents through
the controllers for up to 60 minutes like our battles. The Tiger will
be using them during the next battle.

experimenting with the Talon SR Speed Controller ($60). That's a single
motor controller, so you'll need two of them and a mixing circuit ($40),
which puts the total price in the same ballpark as a dual motor
controller."
The servo mixers are down in the $15 range from Robotmarketplace.com.
I'll be testing one of these tonight with two Talons. Even if a mixer is
required, the $135 spent on two Talons and a mixer is the lowest per amp
cost of any 60+ amp motor controller setup I've seen to date. Also, a
very nice advantage to a two controller setup are lower replacement
costs if a part breaks. A few years ago I blew a FET on one channel of
my dual channel RD-80 controller. Had to replace the entire unit for
$300. With two Talons, the same repair would have been $60. My next tank
will be running Talons with a spare in the toolbox.
