### calculating FDR for OTA-R

Posted:

**Mon Sep 03, 2012 11:58 am**Hi guys,

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.

kind regards,

Davey Zoutenbier
