Servo wire size

[WHITE-TRASH]

So I got to thinking of ways to upgrade things so I started searching here on RCC when I found something sort of related to my quandary in this thread.

My thought is why wouldn't upgrading the quality of copper and size of wire powering the servo help to not only make it more efficient but also up the torque output of the servo? 22 gauge is the standard on higher output servos as far as I can tell but why not up it to 18 or so?

Upping the leads on the batteries and esc to 12 gauge has performance advantages so why wouldn't it on the second highest amp drawing part of the rig too?

22ga stranded copper can handle 7a, which should cover servo applications easily enough. Upgrading to a better quality/heavier gauge wouldn't hurt. Not sure about benefit overall. Next consideration is what's inside the servo. Would it benefit? Would it create a bottleneck, negating the benefit provided by bigger wiring?

Good points.

Additionally, what about the pins & traces in the RX, what can they handle.
There is also differences between a "peak load" vs. a "sustained load".

ESC's and servos tend to be "peak loads" where wire size is not as much an issue.

Keep your wire lengths short, try to keep connections clean & tight and you will be fine.
A minor change in wire wire may help a little, but is it enough to offset the effort to make it work?

I agree that short heavy ga wire runs for carpet cars pulling lots of sustained amps shows a benefit, not so much in crawlers.
At least, not enough for me to go through the effort.

These are the same things I'm wondering. If we could get more current TO the servo is the board able to turn that energy into output.
