That is similar to a question like "how long is a piece of string?"

Without knowing motor details and desired headspeed, you cannot recommend a pinion.
What motor/kv?

Lower pinion teeth is lower headspeed and less load on the battey but not as snappy as higher headspeed you get with more teeth on the pinion.

But as Jim pointed out there is more to that. One question is do you have a flybar. FBL heli generally want/need higher headspeed.

13T works well with a 1600kv motor and no gov. Some will run 14T if using a gov for head room. 15T does not sound like a good match for the stock motor.
