Power Master
Performance
Power Master is a surprisingly powerful device for such a small package. My own tests show that the Dean's Wet Noodle wire attached to PM 6 gets hotter than PM itself. For my high current tests, I use a automotive battery (12V) and starter motor. A Fluke dc clamp meter is used for current measurement. Tests show that PM will operate at variable throttle, without forced ventilation at 95 Amps continuous, and for short periods up to 150 Amps (~10 seconds).
A PM Mk IV was used to replace an expensive top of the line unlimited controller which failed (the power leads melted off the board) due to high gearing required for a track that had tight corners and a very long straight. The car was a 1/10 touring car with a seven turn motor.
A single PM Mk IV was used in a 1/10 scale 4WD using 2 motors, a 12 turn and a 15 turn using two 6 cell battery packs. PM was barely noticeably warm.
Power Master Mk II
A PM Mk II Is still being used in a 1/10 scale monster buggy similar in size to the RS4 long arm buggy, but using a large model aircraft can motor and two 6 cell 2400 mAhr packs in series. The buggy pops wheelies on the straights, and regularly breaks drive shafts and strips gears. PM does not get warm, despite the battery run time of ~3 minutes
