Spur-Pinion @ 2.200 (44: 20)

For a total ratio of 16.109

With 14.8v, 2200kv and 6.3" tire the math for that combo is ~37.9mph

Where our math differs is the second gearing stage of the tranny.
I see the 32T gear on the idle shaft driving the 29T gear on the output shaft. Which means it would only take the 32T gear 0.906 of a revolution to turn the 29T output gear one full revoultion.
Yep, you are correct. Unfortunately the information I originally found on another site was incorrect in that it had the 29 and 32T gears in the tranny backwards. Now that I actually have one and can see the manual, I see that the 29T is the output while the 32T is the idler.
