How to Prevent Pigtail Solder Joints from Disconnecting?
Does anyone have a way to stop the pigtail solder joints disconnecting on the drone? The negative solder joint keeps disconnecting after 5 or so flights. Tried using flux but it just won't stick. Thanks!

Can you upload a picture? I’m guessing you’re not letting the pad get hot enough while soldering.

@danieI this is pretty common, you just aren't getting them fully attached in the first place. you need more heat/flux to fully melt/incorporate the solder onto the pad like @John35588 said. they should look like nice shiny, conformal blobs, but you can see the shadows between the wires and pads where the solder hasn't fully incorporated onto the pad. try preheating the pads a little more and adding a bit more solder to the pads and saturate the wires a bit more before you join them.
