Too many variables to give you the "sweet spot" on gearing. How much endbell timing you are running, how heavy your car is, what rotor you are running, and how large your track is can vary your timing by quite a bit... and the gen2 tekin motor is probably going to be about your least popular motor at this point considering it's so new. I don't know a single person running one at either of my tracks. Having said that, here is where I run. With this combination, the 31/69 is the sweet spot. 30 is slower, and so is 32. It can also vary motor to motor of the same model. (although probably not much).

Fantom APEX 17.5
Fantom 4500 shorty lipo
endbell timing maxed
12.5 HT rotor

Car is blistering fast for a 17.5. This weekends race I ran a fast lap of 14.4... Mod fast lap for the night was 14.3 in a b4.1
