I need to make up a new servo three cable plug. I have the small terminals and plug body but need to know the best method to use to attach cables to the terminals. I have a crimping tool but this seems to crush the terminal flat rather than form a proper crimp. Am I using too much force or is there a special technique to do this. Can I solder the terminals instead of crimping. These have to be pushed into the plug body and I do not know what solder tolerance I have available.
