Fixed Wing vs. Multi rotor ESC's

Has anyone seen a good article that describes the key differences between Fixed Wing ESCs vs. Multi Rotor ESC's? Also how do you identify them as most suppliers do not mention what they are designed for. Yes I know people use fixed wing ESC's on Quads and vise versa, but I am more interested in learning about the key design and feature differences.Furthermore, what is people experience using ESC programming cards? It appears Turnigy has one, but there is no such programming card that would…See More

"I don't believe these features can not be used on fixed wing aircraft if that's what you mean. Are you referring Ublox GPS here?"

"so why are these advanced features only on Ardupilot and not Arducopter? do they apply for AC was well or no? I also seen some of the newer GPS (M8N) have built-in EKF or INS, specially the RTK ones, has anyone looked at those?"

"The switch you are using is the same thing is what you ordered from China except is giving out +5V to energize the relay. Just a put resistor (between one of the leads of the relay and your switch) to drop the voltage down to 3.3 V. First check the…"

"The reason you are getting 0.5V is because a Voltmeter is not a load device. You need a load on Pin 5 to get some values. You can try few things. 1. Connect a servo to Pin 1 using this method. You need a +5V BEC as well for testing. See if it…"
