I'm toying with the idea of getting a variable voltage power supply that allows setting a ceiling for max amp output to do bench work of RC components. Wondering if anyone else has done this and if they've found it useful. My idea is to hook servo's into a receiver on my work bench and do receiver setup and check proper function of servos etc before installation. Probably somewhat boils down to I'd like to get a new toy but I do think it would be useful to bench test components before installing them. Anyone else done this and found it useful?
