This zip wire is a good cheap alternative to the more expensive lines of wire. While its not as flexible as silicone coated wires its not real stiff like cheap wire is. I use this type of wire for making charging adapters and various general purpose RC stuff and also non RC related projects where major flexibility isnt a must but you still want a good quality wire.

This appears to be wire intended for automotive use. As such, the high quality PVC insulation is designed to resist oil and gas. This wire is durable. I purchased the 14 gauge wire. This wire is much better quality than I was expecting. I will definitely buy again!
