Why you need a servo controller for a bomb is beyond me, but here it is.
Radio control receiver circuit, voltage regulator (w/cap for the regulator), and Nickel metal hydride (sub C size, 7.2 v, 3000 milliampere-hour) secondary type battery. Tomaya connector.
You don’t need such a battery for the receiver circuit. The regulator helps to provide the increased power to the motor while steping down the voltage for the receiver. so looks like person didn’t know how to use just the receiver circuit with a lower powered battery.
good for RC cars and robots.
NiMH has no memory effect compared to old NiCad. Clearly Not a Lithium poly as some news sources said.
So very sad and sick to see toy parts being used for such a horrible thing.
