yep that's exactly what spektrum does and sells for $6. The only "glitch" I see on that site is the explanation of what a capacitor does. There is no "noise filtering" going on in there. The capacitor stores energy...essentially a battery but with no cell memory.

The "glitches" from the car are when the mainly from power hungry servos that sucks all the power out of the RX, and your battery pack can't replenish it fast enough, therefore the RX shuts down temporarily.
