Thanks
there is an app on the google play store.. called RC Final GearRatio that i downloaded.. it has the T4 in there.. so all you do.. is put in your spur, and pinion.. and hit calculate.

the thing about finding the right FDR for each track.. usually.. i just see what other guys are running.. and get mine in that ballpark.
