calculating FDR for OTA-R
I have heared several things about calculation your FDR on spur and Pinion.
that that isnt the same as like a 2 belt chassis, my qeustion now remains is this correct?
because I now drive with 3.2 FDR but I have a pinion 27T en Spur 118T what makes 4,37. is this correct or is it different because of the 3 way belt system?
because I want to have a spur pinion for short track and long tracks.
