Presumably there are hundreds of guys on here that have had no issue with soldered signal cables though so maybe I did something wrong or used the wrong solder or whatever. For dummies like me crimps work pretty good.
A signal lead always has at least two soldered joints - at the Rx and at the servo, so solder is not in itself a problem. I have made many extensions by soldering and not had a problem.
