Yeah, you should be able to solder a bullet connector directly to the tab, although, I would personally use a short piece of wire between the tab and bullet for a little more flexibility.

If you do direct-solder, make sure to be careful if attaching male bullets on the tabs because the solder can "wick" onto the actual bullet and may not work right. I would solder female bullets on the motor and use the male bullets on the ESC wires.
