DJI trying to bypass the US Ban of Chinese drones

Once you learn that soldering irons are not made to melt solder - You will start soldering much better. I always use lots of flux. I also only use 63/37 solder on Drones. The flux pens are great if you can find them. always use a soldering iron with an adjustable heat setting and while you are learning LEAVE it at 350 NO MORE for now.
TBS makes practice boards with the most common tabs you will find on Drones
