MAIYUM Solder Wire
This solder works really well. It flows smooth, sticks clean, and doesn’t need a lot of heat to make a solid joint. I’ve used it on XT90 and EC5 connectors with 12 and 10 AWG wires. It handled the thick wire and big terminals with no problem, and the joints come out clean and shiny every time. Definitely a good solder for RC work where you’re constantly swapping connectors or repairing leads. For the quality and price, it’s hard to beat.
