@Jeffvanuden , you never stated What model you have at all. Yes this matters greatly. Many variables are involved. Tire rollout, the final drive ratio, etc.
Buy several pinions to try.
Can't be cheap about this.
12-13T is where to start, and yet still an assumption, based on your rather high KV motor.
2200kv's can be rather steep, assuming for a heavy basher, running 6s packs.

Motor fans are a given.
Govern yourself accordingly.
