Thanks for ur answere but your answere really is making me down :-/ that means i was buying all my 8 ESC for nothing? i mean...still dont understand why always this one arm... even i tryed it with 2 Motors and 2 ESC why the others are working? I need ESC for 12 S thats the reason why i took the YGE 60HV heared they are very good...
thanks anyway...maybe someone else has a idea? Really hope that i dont have to buy 8 other ESC again..
The C Rate of the batterie is high enough i mean i was calculating with c rate for 8 motors so for 4 it really should not be a problem the cable of the motors to the ESC have the same length like the others.
ESC i found which i could maybe use are that?
