i don't know how you get at 9:1 gearing ratio. You must forget to include the spur/pinion.

A 17T pinion with a 51T spur (i assume you are using a MOD1 spur/pinion?) wll give you a 14.7:1 ratio with a 35 mph topspeed. a 20T pinion will give you a 40 mph topspeed.

(assuming you are going to use 4S. according to your signature...)
