I've owned the Hobbico digital voltmeter and it served me fine before leaving the hobby. I'm back and getting the DX7 for Christmas.

Is there any reason to change voltmeters to the Hanger 9 model? The Hobbico puts on a 250mA simulated load and the Hanger 9 has .5A, 1A, and 2A simulated load. Do I need the variable loads. What is the conversion to mAs - 50, 100, and 200????

Thanks in advance!!
