I recently fried my ESC and replaced it. Different brand. I connected my Eagle A3 SE gyro. However, when I powered up the throttle it would only run for a few seconds then stop. The ESC would go thru the startup sequence, then run again for a few seconds. I disconnected the gyro but the motor would still stop. I spent so many frustrating hours trying to solve this issue. Different receivers, different transmitters, different batteries. Nothing worked. So I took a very close look at my setup. Good receiver. Fully charged lipo. Control surfaces worked great. The ESC would get very warm to the touch. I then inspected my servos. I saw the problem. I had 2 standard servos and 1 micro servo. I swapped the 2 standard servos with micro size. I powered up. Viola' It worked. Apparently the ESC could not handle the amperage of the larger servos. This morning I will connect my gyro and see if it works. I have really neglected my wife for the past 2 days with this problem. I'll make it up to her later. (Yeah, right. Get real)
