Stock gearing from the book is 21/70. They include a 25t pinion as the "speed gear". The 70t spur is only one listed.

If my Math is correct, to get close to 3.6 you would need to be around a 47/60 in 48 pitch or 63/80 in 64p.

If 21/70 results in a 9.49 FDR, then the internal ratio is around 2.85, meaning your pinion:spur ratio needs to be around 1.26.

Will it take stand spur gears, or does it use special Traxxas only spurs?

Don't know yet on spur. The book only lists the 70t. Going to try to get a actual look at the gear over weekend. I had a feeling it was going to be geared wrong for any established race class. My USGT car is geared 35/69.

The spur gear is the kind that slides on over the drive shaft and is held in place by a pin...NOT a standard touring car type...TRA8357

According to the ratio calc I have its would be the same internal as a xo-1

If the internal ratio of 2.85 is correct, then with a 70 tooth spur you would have to have between 50-55 tooth pinion to be in VTA land...biggest you can put on by the manual is a 28.

The motor mount is similar to a Tamiya - a bunch of different holes to pick from depending on pinion.

I've known the owner of the shop for years, he pulled one off to the side for me when it came in and called me. One of their employees installed the Bluetooth module for me as well while I was there.
