That really depends on your track and motor so there isn't really a magic number until you've found it your self, but you can use other peoples advice on what a good starting point would be.
You should at least build up a small stock pile of pinions so you can easily change your gearing if you need to. It would also be a good idea to have at least 1 spare spur for just in case you destroy one while racing so you can continue to race.
In my TC4 I'm currently geared at 30P/69S @ 5.7 with a Peak Racing Hellfire 27t motor but the motor is getting hot but this is on a large open outer track with elevation change.
is very useful.
