Yes, I tested six F40PHs from MTH at the same time. They drew about 6 amps. The F40PHs were a mixed bag; some I loved, some were OK, and one missed the mark. Below I listed each engine tested, and the time it appears in the video. Note, however, that with the exception of the 5th F40PH, the Run 8 run-up for all the units can be found at 3:08.
