thanks

No one has had this happen to them?

Not sure what you mean by receiver wires coming off? Did they come unsoldered from the board? Maybe you just need a better solder iron. Some of the low wattage irons don't get hot enough.

Yes the wires came off the soldering board. As for the iron it has multiple settings as to how hot it gets I believe it goes to about 700degrees and i have battery wires from the mamba monster very easily I don't see how these thinner ones need more heat I also use flux but still nothing. I believe the little piece that needs to be soldered to came off the little tab because the other wire soldered fine. Is there another place I can use to solder it to and get ground connection?

If the solder tab has come off the board it's curtains!
