Total Newbie on a budget

[lowndsy]

How would I use the plug and play mixer in amongst that setup to get CH3 control both wheels, turning in opposite directions?

I haven't tested if it reverses one side in a turn. The point of little units like the mtronic is that there aren't any settings to worry about so I would imagine it either works or it doesn't.

Might have everything running properly at the weekend, so will check then.
