Gear ratio for deerdale?
 

Hi guys, I've just finished building a new losi 8ight E 3.0 and am going to race at deerdale with it. I'll be using a team orion R8 setup with a 2100kv motor. I'll be powering it with twin 7.4v 2s packs (6000mah) was wondering what gearing to go for and what pinion sizes I should be looking at as a ballpark range?
