Battery Power Leads from F/C

Hi Everyone,
Its taken some time but Im almost at the end of my 2nd build, I really would like some advise on cable sizes to FC for power.
Would a 14awg be sufficient for a 4s lipo, I have a speedybee f7 stack, caddx tarsier, rush tank ultimate II, and 2450 iflight motors.

Much appreciate any assistance.
 
Probably fine, ultimately amount of current drawn through a given wire is what's going to cause loss as heat from resistance in the wire. If the heat has no where to dissipate it can build up and cook components or desolder things but given the thing is likely ripping through the air when it's in high current draw scenarios it's sort of a self solving thing (higher speed is more air flow is more cooling which you need for the higher current draw). A thicker wire will always result in less electrical loss but have to also consider weight of things when it comes to flying and how that effects flight time.
 
The simple rule to go by is stick to whatever gauge the mfg put on a battery leads to not "limit" things though or incidentally bleed off a lot of power as heat.
