Make sure the wedge tip (not the pointy tip) is installed to the soldering iron
Turn on the Soldering iron
Set the temp to 850 F
Recognize the difference between the Battery XT60 connector and the ESC XT60 Connector
Take the XT60 Battery and ESC connectors and plug them into each other (make sure you don't solder the battery connector)
Strip insulation off the Red and Black ESC wires
Pinch and twist the wire strands if frayed
Put heat shrink tube on the Black and Red ESC wires
Secure the clip in the alligator clip with the negative marker up (make sure you grabbed the battery connector)
Place the Black Wire into the back side of the negative bullet connector (it should stay there without touching it)
WAIT: double check you are going to solder the ESC XT60 Connector and not the Battery XT60 Connector
Clean the tip of the soldering iron by rubbing it on the pad
Melt some solder onto the flat side of the soldering iron tip
Place the tip under the back side of the bullet connector (using the side with the melted solder)
Gently put the tip of the solder on the wire in the bullet connector and wait for it to start melting (try avoid melting the plastic)
Fill the bullet connector with solder until it is about to overflow
Repeat steps 5 - 14 for the Positive bullet connector and Red Wire
Wait a minute for the pug to cool.
Slide the heat shrink tubes up to the XT60 Connector
Using the heat gun, shrink the heat shrink tubes
Double check Red wire goes to Positive and Black Wire goes to Negative.
All done!
