I've been having ESC arming problems with a couple of ACM versions.
The last two versions I flew, v37 and 42, there was no problem, but with some other versions including the recent v43 not all ESC's arm immediatly. They keep beeping for a while (30-45sec) and then finally arm. Not all ESC's do this. Once they are all armed I have no problems flying.
I think this has something to do with minimum throttle but why don't I have the same problem with for example v42???
What could I change in the code so all ESC arm at once??
They are all calibrated, so thats not the problem.
