Wouldn't you think that someone with a EE degree and 15 years teaching both basic and advanced electronics would have known that? A simple ESC with a linear BEC rated for 2 amps would have to dissapate 14 watts (12V - 7V X 2 Amps) if four servos that drew .5 amps each were all activated at once. The linear regulator/s would work OK for a short period of time while dissapating that kind of power. Can you imagine the size of a resistor that would dissapate that kind of power while NOT providing any voltage regulation to the receiver or servos?
