Keep your builds high quality with Silicone Sheathed Wire. Unlike standard wiring with plastic sheathing, silicone sheathed wire is more flexible and durable and it's also resistant to high temperatures! You can now solder away with confidence without worrying that your cable sheating is going to melt. And the high fatigue resistance will make sure your quad never falls out of the sky because of a broken cable!
24 AWG is the preferred size for signal wires between the receiver, flight controller and speed controllers.
