Steve is right; the minimum switching time for FETs is determined by the capacitive load on the gate, so you want to minimize that whenever possible. Long wires (or, wires in general) aren't ideal for this, but if you use them, they should be of the same length. What frequency does the pwm controller switch at?
Aside from that, make sure you use appropriate heatsinks (I do see that you mentioned it, but I cringed a little bit when I saw these FETs mounted to wood). You won't even begin to approach the rated current handling without removing all that heat (The "on resistance" (RDSon) for the FET will increase with the temperature, so they must be kept cool). Aside from that, it looks like a solid setup if direction is not a factor. Teh FETs you chose have a nice low RDSon value, so I'd say they were a good choice -- You are currently subscribed to the "R/C Tank Combat" group.
