Using this cable set is easy. First, figure out which wire size you need for your multi - copter building project. The 14awg cables are great for high - current applications, while the 18awg and 26awg are suitable for other connections. When handling the wires, be gentle to avoid damaging them. Keep the box in a dry place to prevent the wires from getting wet. If you don't use all the cable at once, you can store the box safely for future use. Also, make sure to cut the wires to the right length with proper tools to get a clean cut.
