Maximum length between Esc & Motor

Hi All i'm sure this qestion has been asked before
i need to move my esc as far back as i possibly can to be able to get the COG right in one of my planes but dont want to kill a 500+ $ esc , the minimum that i need is 300mm (12 inches)is this possible ? and will i loose any performance by doing so?
I know that i could add some wheight to the tail of the plane but this thing already wheights 800 grams more then what it's supposed to be
Many thanks

Between ESC and motor, length is not critical. You won't notice a 12" extension at all. The critical side is between ESC and battery, and even there, 12" would be tolerable. I'd match the motor wire gauge with good quality silicon wires.

I'd use the bullets too. There is very little loss in those. Good luck with the installation.

You shouldn't have any worries extending your ESC output wires your motor is full of wire that side of the ESC is more tolerant of inductance than the battery side. The only issue I've ever heard from longer ESC motor wires is minor RF interference with the rx this can be avoided by braiding or twisting the three motor wires together or careful wire placement.
