Then I tried to measure the no load current using:
-3s 2200 old battery from an ArtTech SU-27 with 12.55V at the start
Results:
-ESC: HobbyKing 6A ESC unknown settings: 0.33Ap, 4.1Wp, 12.53Vm
-ESC: HobbyKing BlueSeries 30A ESC unknown settings: 0.40Ap, 5.0Wp, 12.52Vm

Problem: for both ESCs, at maximum throttle, the rpm was not constant but varying at about 1Hz, giving a "wailing" sound.
I'm not sure why that happened, maybe the rpm was too high for the ESCs ? Or maybe I need to change their settings ?

I'll discount these (the no load with 3s battery) results for now since they obviously are not correct.
