Re: Omni on the cheap.
Sand-

I'm not entirely sure on the first problem, of mixing channels on an RC controller. I'm not really sure just how the control system needs to be set up (I've never really gotten my head around omni drives). I know that some very advanced (expensive) R/C controllers can mix channels to one axis, often for helicopter control. Some of the really nice controllers actually have rather advanced processing power, and can be programmed to mix and scale channels all over the place. But, you said you liked cheap...

As for the speed controllers, a lot will depend on the typical current draw and duration of run. Most hobby controllers are designed to run a fairly small motor for around 10 minutes at a time. How long did you want to run them? If it's rated for 16 amps, you can probably get away with 25 amps, for short periods. With a bunch of motors moving that light a weight, you can probably get away with it. You'll probably be limited by how much current the battery can supply anyways (unless you are using a lead acid type).

You might consider putting the controllers under a muffin fan, or some other form of cooling. Water cooling? Would add to the geek factor for sure...
