If you are new to soldering, it can be slightly intimidating having to solder a tiny wire onto an expensive flight controller. With the mamba soldering practice board you can get some practice first without worrying about burning your expensive electronics. This is a blank PCB with a load of soldering pads for you to practice on. The layout includes pretty much every type and size of soldering point you will encounter in this hobby. And as a little bonus you can some soldering with the board too.
