Must-Know Soldering Tips

There is always that occasional event to do some soldering. When we need to supplement some connectors to a battery pack, or to make a set of wiring adapters for your battery charger, regulating feverishness and fiery steel to join wires together is one of a oldest do-it-yourself tasks for RC hobbyists. The charge is customarily unequivocally simple: usually supplement feverishness and solder, and you’re done! But for a haven’t-done-it-yet newcomers in a crowd, there’s a tiny some-more to it than that.  Here are a few useful hints to get we started!


For simple wire, engine depot and speed control soldering, you’ll need:

  • 40/60 rosin-core solder
  •  25 to 40W soldering gun or pen
  •  Moist consume to purify a soldering tip
  •  Basic collection (clothespins and alligator clips) to reason parts, pliers, etc.
  •  Tube of soldering motion for soldering and tinning steel parts
  •  Heat-shrink tubing to isolate handle solder joints


1 Start by stripping a cosmetic insulation off a ends of a wires (usually, 3/16- to 1/2-inch is plenty).

2 Set adult a wires in your holding jig. Tin a ends of a wires by simply requesting a tiny volume of solder to a unprotected handle and concede it to upsurge into a strands. Apply a feverishness to one side of a handle and hold a other side with a solder. When a handle is prohibited enough, a solder will upsurge into a handle braiding.


A square of pine, dual wooden clothespins and some ZAP is all that’s indispensable to make a holding hop for soldering.
You can snap off a clothespins simply and reglue for opposite jobs. The cost is nothing!
Commercial soldering jigs like this one from Tingler Innovations ( are also a good investment.

The initial thing you’ll learn is that to solder anything together, you’ll need an additional set of hands, generally when perplexing to solder dual wires together. With solder in one palm and a soldering coop in a other, how do we forestall a wires from relocating around? With a handy-dandy “third-hand” holding jig, of course! You can simply build such a holding assist with a timber bottom and a integrate of wooden clothespins glued to it. A holding hop or tie will compensate off a unequivocally initial time we use it-take my word for it! You can glue a clothespins in a accurate chain we need for a specific pursuit and afterwards we can snap them off and reposition them whenever a need arises. we don’t consider that we can unequivocally do a good soldering pursuit but one!

3 Slip some heat-shrink tubing over a wires and pull them divided from a solder corner area. Position a ends of a wires together, afterwards reheat a wire. Watch a solder tinning. When it liquefies and flows together, supplement usually a tiny some-more solder to entirely fill in a joint.

4 Remove a solder and a feverishness and concede a corner to cold off. Don’t pierce or nudge a wires. If they pierce while a solder is still prohibited and fluid, you’ll emanate a diseased “cold joint” that can mangle simply from quivering while your craft is in a air.


  • ¶ When in doubt, use a bigger soldering pen. More feverishness is always improved than not enough. If your solder takes some-more than dual or 3 seconds to start flowing, we don’t have adequate heat.
  • ¶ For many bland soldering, customary rosin-core solder works great. For unequivocally fine-wire gauges (like servo leads), use skinny solid-core solder and request a dab of solder motion pulp to a wires.
  • ¶ Keep your soldering tip clean. Use a damp consume and clean a tip between any use.
  • ¶ Use usually resin-core solder or motion pulp with braided wire. Liquid soldering motion can wick into a cosmetic insulation and means your wires to erode over time.

5 Once a solder corner has cooled, slip a heat-shrink tubing over a corner and cringe it into place. we like to do this with a prohibited atmosphere gun used for timorous cosmetic covering. It’s discerning and easy and a feverishness gun won’t warp a wires or a solder.

Of course, it takes use to urge your skills so cut adult some handle and solder a pieces behind together. You’ll be a soldering pro in no time during all!
