I purchased a new Eflight 20a esc to replace the burned out unit in my Typhoon. I did not connect the engine leads, but I hooked it up to my reciever. The servos were also conected to reciever. When I plugged the batter in, the esc did not beep but the servos went full travel in the opsite direction. My question is since the esc did not beep, is there a problem with the esc? I am using a 3s lipo when I plug it in. The original esc melted on the sixth flight. I might have cooked my reviever as well, but I am worried since the esc did not beep when I plugged it in. I am using a GWS reciever that worked perfectly until the melt down. I was also worried about hooking up the motor before I program the esc to lipo batteries. I dont know if I fried the motor as well.

I'm not familiar with that particular ESC, but I'll pass along one item of information about ESCs in general.

ESCs use the motor to produce their sounds! The motor acts as the ESC's "speaker," so you will not hear any beeps unless the motor is connected. The ESC energizes the motor windings to produce sound.

Thanks for the info. I did not know that.

yes everything has to be connected to hear anything. at least with eflite esc

I guess I am the next person to win the Darwin award. After I pulled everthing apart because of the jittering I bought a new reciever and it still did the same thing. So I got one of my full size recievers an tried it with no luck. It turns out that I had my radio in pcm instead of ppm. When I switched it everything worked great. Thanks for the advice. It did beep when I hooked up the engine. I cant wait for the wind to die down so I can try it out in a couple of days.
