RE: Nomadio React 2.4GHz Radio
The reason they did not put a regulator in is the same reason they did not put a diode in it so if you hook up the batter backwards it does not fry it. Same reason they left so many holding the bag THEY JUST DID NOT CARE ABOUT SCREWING PEOPLE! Keep us posted on what you fine and I wish you luck.
You can all so bind the older style Spektrum RX to the React and no you cannot bind a 4PK to a Nomadio RX.
