I run the same ESC in my SWAMBC F3 Falcon with 19turn 540 motor, 6 GP 3300 sub C, Graupner 2318.29 or 2327.29, and an F2 version 12turn 540 2:1 geared, 6 IB 3800, Graupner 2330.32 both draw 30+A for 5mins. The esc was getting to 70'C before water cooling, now typically about half that, the 1/8in tubes are epoxied into slots machined through the cooling fins as it didn't fit my layout adding the pipes along the fins.
