(Would be helpful to know for the 43t stock spur and the 45t metal spur as I plan to upgrade to the metal spur)
Any advice is appreciated!!
With the 43 spur you will not really get a perfect setup for a 2100KV motor. You would have to try either 13 or 14 pinion. However, with a 45 spur a 14 pinion would be a good match. I have based this on calculation of what the TLR factory drivers are using with 1950KV motor or 2200KV motor.
I have a 2050KV motor and will use 43/14 as a starting point, but a 44/14 would probably be a better choice.
