advice on soldering
Im trying to solder wires and connectors to my new brushless motor but for some reason the solder just wont take to the motor tabs.
Ive cleaned the tabs and have tried a 40watt and a 100 watt iron. Does solder go out of date? Any suggestions.

when you say you've cleaned the tabs, did you use flux ?
I find that taking an exacto blade and creating a criss cross pattern on the tabs helps sometimes.

ive lightly scored the tabs with fine sand paper to clean but the solder just wont adhere to the tabs.
I'm going to buy some new solder today as mine is about three years old so the solder mite be off, dont know if it has an expiry date but cant think what else it could be from stopping it from flowing and sticking.

Solder doesn't go off, but the lead free stuff that has been forced on us is shite. If you can't get your hands on any 60/40 leaded solder you will need a good plumber's flux in addition to the stuff in the solder. Powerflo flux is pretty good.

the solder ive been using is lead free, will try to get some with lead as you guys recommended.
Made it stick in the but am not happy with it as it looks real messy, think i will re-do all the joints with fresh solder. Thanks for the help.

Yeh we got some stuff which doesn't smoke and is lead free in at work, I took some to use (not stolen, they were sent loads of free samples), and it was garbage!
I have some lead 60/40 stuff, quite thick solder, not the thin stuff, and it is miles better. It smokes like mad and stings my eyes, but hey-ho.
