Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 No-Clean, 63/37 Alloy, 0.031 Diameter

Nice size for hand held soldering of wires

Best solder for racing drone applications

I regret learning to solder with other sub-par leaded solders. This size (20AWG) has worked well for me for small electronics pads (e.g. flight controllers) and associated higher-gauge wiring, as well as more substantial pads (e.g. electronic speed controllers) with wire gauges occasionally dipping to 8AWG without any issue. When using the right flux, and only when needed, you cant go wrong with this solder unless you need a lead-free variant.

Highly recommended -- not the cheapest but worth the price. I wish it came in half the size / half the price option because i did not need that much.

Great stuff, Ive been using this in all my projects for the past 4 years, flows great, 63/37 never leaves a cold joint, the 0.031 is perfect for most through hole components. Ive built guitar pedals, FPV drones, keyboards, and made loads of repairs, Ive never thought about my solder after picking up a spool of Kester, until recently - Im running out!

I purchased this soldering wire on the recommendation of many an RC enthusiast. I initially had some difficulty making this solder “stick” to PCB pads (@350C), but after cleaning and recoating my soldering tip, thereby removing my old soldering alloy and replacing it with the new, it was smooth sailing. The solder flows easily and sets quickly once the tip is removed. It also results in a lot less flux residue than what I am use to. Minimal cleanup, if any. Highly recommended. Thank you for shipping to South Africa for me. Could not find Kester at all, locally.

Perfect for light use, hobbyists, etc.

Kester is the best stuff out there I think. This is a nice messless solder.

Works quite well for me.

If youre going to spend $27 on a roll of solder, you kind of expect to get a quality product. However, in my case the roll showed up with a big chunk taken from the side of the roll. The chunk cut through the first and second layers of the solder. Its still usable but prolly going cut the top two layers off.
