Featherweight wire gauge?

Hi all, noob time...I have searched the forums to no avail regarding this. I'm wondering if you guys can help?

Building a featherweight with 2 12v cordless drill motors, 9.6v battery, most likely using 30A rated ESCs.

Question is, what gauge wire do I need to use?

I understand a few guys use 14A but is that too low as I'll be using 30A ESCS?

#confused

Thanks.

I use 14 gauge wire for higher powered motors and haven't had any issues after years of operation. The trick is that you are seldom pulling high current for long periods, so the average long-term current is relatively low and the wire stays cool. I recommend high flexibility wire with silicon insulation, like Hobbyking sells, but automotive wire is fine too.

I always over size my wiring by a gauge or two. Unless weight is a real issue then you won't go wrong throwing a few extra grams at your wiring.

Problem with wiring is have to go on judgement & experience. Current rating of cables are continuous which are a nonsense for what we do. Also cables can operate upto 70deg c for pvc (other compounds can be 90deg or 105deg) so a bit of heat isnt necessarily an issue. I normally use 1.5mm for feathers but it does get warm if you have big drive motors and a spinner.

14awg or 2.5mm is likely to be fine for everything in a feather but 16awg or 1.5mm is likely to be ok for a couple of drills.

The 9.6v suggests a NiMH/NiCd pack, which may well have 14awg on it (or less), in which case there's little point in using anything thicker than that for the main power stuff.

You could drop to 16awg for the drives, but as others have said a bit of overkill is no bad thing and you only need to buy the one thickness if you stay all 14awg. Later down the line you're more likely to use 14awg+ anyway so building up stock helps too.

This is assuming the popular flexible silicone type wire mentioned above, such as: http://www.hobbyking.com/hobbyking/s...icon_Wire.html

Thanks guys, I think 14wg is the one to go for :)
