B4 17.5 gear ratio

Anyone offer any advice on gear ratios.
I have plenty of 17.5 motors and as a newbie with a buggy i think it be quick enough. Rather go round bit slower than just crash every corner lol.

They say a FDR of about 5.5 for 17.5 stock in 2wd Buggy.

So...I would say 69t Spur (AS9648) and 31t pinion as a starting point.

Maybe 30t for indoor

Your paperwork for your motors should give a recommended FDR,
