What's the wire gauge size for CT70s?

Replacing some wires on my rotor. What gauge size should I get? 16 or 18?

I would not go any larger 18 ga. You'll have an incredibly tight fit if you try to use 16 ga - especially - if you try to route all the way to the stator plug.

Now for the original size, for most wires except the battery, I think 0.75mm2 was originally used (which is close to 18ga). I'm sure that someone will chime in and nail the original size.

Thanks! So, 18 gauge it is?
