XXD 30A ESC Callibration Issue?

[nicefellow1234]

Hi,

I have completed building my F450 Quad with following setup as : 1) XXD A2212 1000 KV Motors With 1045 Props 2) XXD 30A ESC's 3) 2650mAH 3S Battery 4) 450mm Frame 5) KK 2.15 Flight Controller 6) Dynam 4 CH Transmitter With 7 CH Receiver So I am having issue in calibration of ESC's...I can't hear the 2nd beeps and also beeps are of differrent sounds..Also I haven't flashed the ESC's...These are running on stock firmware...! My Motors are turning on different times when I increase throttle..Hence the Quad flips from one side to another..Is not really flying very straight from the ground..! Also when calibrating all ESC's at once from KK Board through throttle passthrough so during that time while when 1 & 4 Buttons are pressed the motors all starts very nicely at same time but when I remove my fingers from buttons so they go back again to their different times..and then do not starts at same time..I have tried every Calibration possible way and it isn't working..! So any help would be appreciated on this issue please..!

If the motors behave good with throttle passthru it is obvious that esc calibration is fine and thus this issue is in totally wrong place please close it. The problem is in your FC board settings/connections/orientation.
