It's a good idea when soldering Deans, to put an unused plug on the end of the one you're soldering. It will keep the plastic from melting and make the plug unusable. Hold the heat on it for just a little too long, and it will happen.
I prefer EC3 and EC5's, for 1/10 and 1/8 application. They're easier to solder right IMO.
The TRX plugs are good as well, and easy to solder. As long as you don't let the solder flow to far down the connector. There's a small mark on each gold prong, easy enough to see. But if the solder gets past that mark, the prongs won't go in all the way in the housing.
