Unhappy roll out for a complete beginer

i have recently bought a Tamiya TT-01 and would like to set the car up so it has a 40 roll out so i can race it at the local RC centre. That is easier than it sounds for a person like myself with no mathmatical experience!!.Can someone help! I cant even work out the ratio of my diff so have no idea where to start .I know my SPUR GEAR IS 61T and my PINION GEAR IS 19T if that helps out . Hope to hear from someone soon. (going RC-INSANE)

Cheers CONVERT328
