RE: Turnigy LiPo and Deans connectors
When soldering large wire you need several things without exception. A non-corrosive soldering flux, a soldering iron [NOT A Gun] at least 250W, 500W OK also, Solder flux [Electrical NOT plumbers paste as it is corrosive]and solder for electrical use [NOT Plumbers solder]. I sould cut off the old connector, as you want to start with clean bare wires. Strip the wire only as far back as necessary to insert it in the bullet. Twist the wires to control the loose ends. Apply flux, allow iron the heat to FULL temp, with wire held in a clamp or other device to free you hands take the solder in hand place the iron under the wires end. the flux will boil, when this happens apply ONLY enough solder to tin the ends, excess solder will make it difficult to force the wire in the bullet. Put a little flux in the bullet, insert the wire. Again with the iron at FULL temp, place it on the bottom of the bullet, the flux will boil and you should see the solder on the wire start to melt. Apply solder to connection, again a bunch of extra solder only adds weight, the important solder should be in the bullet!!!
