How does the receiver get power with the Reactor regulator?
The RX is powered by 3 leads from the reactor at 5.2V. The three leads double as power input to the RX and remaining channels, and they also deliever the signal from the three high power servos on the Reactor’s servo power bus. This is a very unique design that no other regulator features. The power is more efficiently sent directly to the servos rather than through multiple connections where power is often lost. The three power leads to the RX also are redunant and can supply more current than a single connector would.
