Yep, large scale RC planes.
I found the magazine, I was wrong about the bananna plug sockets, there's only two parralleled per phase.
Using my highly accurate method of using a ruler on the photo and measuring components I know the size of, I'd say the mainboard(power electronics) is about 120mm (5")long, by 75mm wide(3")-ish.
There are 24 large mosfets on this board, and two bussbars on the sides to carry the current, looks like the mosfet's are D2PAK's, definatelly bigger than DPAK's(approx same body size as a TO-220).
The daughterboard has all the control electronics(inc. an Atmel ATMEGA8) and is dwarfed by the mainboard.
I'd have a guess and say the mainboard is of 2oz copper, so the tracks can handle the current. The phase tracks look about 20mm wide.
Edit:
ahhh, I found some pictures of a slightly different one.
This is the Schulze Future-40.160WK which is a 40volt 160A controller
The photo I have in the magazine is of the 32.170, 32 volt x 170A.
The only difference seems to be that there are more mosfets on the 40volt version (higher voltage fets have higher resistance), and the daughterboard is covered.

Nice eh? Might be pricey tho!.
Simo.
