Hello all.
I just finished building the S which is my 1st car. Quit an interesting experience. I started reading this thread (I'm on pg 12) but it will take a while to catch up. I learned some good stuff already.
I just mounted the motor (HobbyWing 9T) & am trying to decide what pinion to use. I've been reading about the FDR but not sure how to relate the gear chart to motor turns or kV. The chart shows pinions from 33 to 18 for the 80T spur gear. The FDR ranges from 8.44 to 4.61.
Any hints on how to choose or directions to where I can read up on it? Thanks.
Chuck
