Try a new tip on the iron, it could help. Also use something like deans or radio shack solder, both work good.

like said before, use flux, it works great when stuff just wont stick. If that doesnt work, then like said before, try to use a different solder. Also, i believe 75 watts is overkill, if i remember right, 40-45 watts should do fine. And if you can spare the extra cash, try to get a base that you can adjust the temperature, instead of just straight from the wall. Everyone at my track recommened getting the tip up to at least 700 degrees.

not sure on your soldering process...
but make sure the tip is clean, then tin it, tin the wire...touch the tip to the motor tab...if the tab already has solder on it...see the solder "wet"...place the tinned motor wire to it and watch it "wet"...remove the iron,,allow a few seconds for the solder to cool..
without a proper techniqe...sometimes nothing will ever stick
Most importantly....a clean tip is the key to soldering...make sure to keep the tip tinned at all times....and wipe it clean and tin it prior to turning it off

you may also want to sand the tabs a little bit to remove some of the "glossiness" on the tabs. I normally do this to a new motor before I install it for the first time

When I sand my tabs I use the cutting wheel on a dremel and put notch like things in the tabs to get a lot of "traction" for the solder.

Make sure you are using the proper solder 60/40 mix.

It really is not a solder issue as an type of solder should stick...even if it is not the corect type of solder to use in RC applications. Chances are the soldering iron is not getting hot enough.
If the solder is not sticking, I doubt that flux will help the situation either. Try getting a hotter iron.

which iron is it? how old and what kind of tip? The soldering iron is probably not getting hot enough-you should have no problems getting solder to stick to an endbell.
