How to solder bullet connectors

A bit of "back to the basics" kind of article here.
When I started off soldering things to other things I always found it hard to obtain a smooth result, without too much solder, or without keeping the soldering iron on the spot for too long, or generally making a mess.
It took a bit of practice, but now I am quite confident in my soldering skills, and I made a quick video to show how I solder 3,5mm gold bullet connectors to motor and ESCs wires.

This is what the majority of rc modellers will mostly have to face while building their kits, so I consider it pretty important to get it right.

- First of all I recommend using a small vice or some clamping tool to hold your connector and free your hands. I successfully use the inexpensive hobbyking one.

- After that locate the little hole on the connector and place the tip of your soldering iron inside it to heat it up.

- After a couple of second the connector will be hot enough to melt the solder, so just fill it up a little over half way through.

- Holding the iron where it is, place your pre tinned wire inside the connector and allow for the solder to penetrate the wire strands in order to maximise the current flow. It will not take more than 4 or 5 seconds.

- You are done, shrink wrap the connection and move on to the next!


I left out of the video the shrink wrap part, I believe it is straightforward enough to be skipped.
