Talking Is bigger always Better?

when it comes to wiring the esc or battery, are bigger wires always better?

I suppose the bigger the wire the more resistance,

around 14-12 gauge seems to be the norm,

Bigger wire is generally less resistance. I don't really see any need for anything bigger than 12guage, yet.

I've been told that size doesn't matter.

larger wire less resistance. The only place where a larger wire can be a problem is in 12th pan and some 10th pan where a thick wire can cause some tweeking issues and if your not carefull reduce even left and right rotation of the rear pod

but 12g is the norm

It is not the size of the wire that matters, but how you use it.

Bigger is wires is better, but have to make sure the mass of the wires that you have do not change your settings.

Default I read in one of the RC mags...

that you should go with a larger neg. wire from the speedo to the battery and the neg. wire from the speedo to the motor. You can use whatever wire that comes with the speedo in other areas. Use good plugs like Orions poles and keep the wires as short as possible. My 2 cents.

12 gauge wire can handle more amps.

Could anyone tell me the pros and cons of silicon wire and normal wire?

Silicone wire has a more flexible sheath.

Silicon Wire is generally more flexible and as such is easier to work with. With wire the lower the gauge the bigger/thicker the wire. As has been said 12 - 14 gauge is what is most commonly used for R/C motor, esc and battery connections. I'm pretty sure servo wires are about 22 or 24 gauge.

The thicker the wire the less resistance (think of water flowing down a pipe, the wider the pipe the more water can flow through) The length of the wire also changes resistance. The shorter the wire the less resistance.

As such i keep all of my wires as short as possible and use deans 'wet noodle' 12gauge wire for all battery and motor connections.

While we are on the subject of resistance you must realise that any advantage gained by having shorter or fatter wires will be lost at a bad solder joint. Solder is not a great conductor of electricity and as such not too much should be used. A good strong joint with alot of contact is better than one with a huge blob of solder. Also remeber that whenever you heat a piece of metal (eg. copper wire) you change it's atomic structure. Heat will actually increase the resistance of the wire so use a hot iron for minimal amounts of time. If you really want to get into it change/replace any wires that you heat often, such as battery to esc wires if you direct solder your packs in.

Some people will say that heat doesn't make much difference but in most topend industrial applications (aircraft and the like) electrical connections are made using crimps not solder just to ensure that no failure will occur
