It occured to me that it would be very useful to have a test device that was a universal test device for virtually any brushed and brushless motors, hall effect throttles, and perhaps even for testing circuits are ok on motors. This would be especially valuable for controllers, to see that they are working properly, by merely plugging in the (6 wires?, 3 3 or 4 for the hall effect sensors, and two or 3 for the power out put and the 2 for power input?) perhaps something as big as the average size multimeter, but with special adaptation for this purpose to make the task be done faster and more efficiently, and even giving data on what elements within the controler are not working properly?
