Yes, you see a 40t spur. It's supposed to be using a 38t, but the hobby shop was out when I ran over there today. The center is running a 44t on the diff and 20t on the pinion for 2.2:1. With the 38t spur, a 2200kv motor I designed it for, and a 15t pinion on the motor it will go 35mph on truggy sized tires. From there I designed it to fit from an 11t to a 20t motor pinion to adjust the speed, reaching up to 46 with the motor and tires specced here. If I get a speed urge, I can change the center gearing.
