Default Help with gearing for my new build (beginner)

hello, I just ordered a Sakura Racing xi Sport 1/10 scale car and I will be putting a 9 turn 4370kv brushless motor in it with 2s lipo. The internal drive ratio of this car is 2:1 but I was wondering what pinion/spur gear setup would be best for this chassis and motor combo? 48 or 64 pitch? Is an FDR of 4 good to start with? I will be just messing around with it in my house and driveway might go to local track to mess around, no competitive racing though.

no, a FDR of 4.0 is better for a 21.5T motor, I would start closer with a FDR around 6.5
