Im using the stock 3dr 20 amp escs on my arducopter. I programmed 3 escs manually because I coulden't figure out the automatic programming. The last esc won't program. It always turns on, gives the start up beeps, the lipo beeps, and every few seconds it gives a single beep.
Any idea what the problem is?
I had similar last week with my new setup. It turned out that I had a dodgy ESC. It worked fine on its own, but didnt work when I had all 4 plugged in which added to the confusion.
I purchased another EXC and it solved the issue.
Do you also have a programming leaflet with the ESC as it usually tells you what the beeps mean ?
