I need to step in here an say a few things about hot glue...
The glue is at or near the same temperature as the gun it comes from. In some cases that is enough of a thermal shock to damage critical electronic components so, no, it is not an industry "standard". Depending on where it is used, it can have other than insulator properties. I would not want to depend on it providing high voltage protection or insulating a temperature critical capacitor. And the one thing no one has pointed out is what happens when you want to remove or modify what is attached with hot glue? It requires getting everything up to the melting point to pull it apart or trying to cut it apart with a knife. Often it goes where you don't want it.
What industry does use (and it looks a lot like hot glue) is paraffin. It is easy to melt, pour, scrape away, reposition etc. Again, there are places you wouldn't use it. (i.e. near a heatsink or other hot component, high voltage or certain RF circuits.)
We found that using square header pins (just like the ones on the RC) which fit snugly and deeply in the connectors work much better than the stamped male pins of a PWM cable. Wires soldered to the end make for a low profile and allows the wires to dress out to the side where they can easily be secured by the enclosure or ty wraps. A little dot of hot glue on each solder point (this is an appropriate use), heatshrink, or electrical tape to insulate the soldered connection (before insertion) works very well, and doesn't damage any of the wire or connectors.
