there is no magic roll out- each motor is different- your driving style and luck in your heats and main. At the birds and my home track I did an experiment that worked for me. But I will not tell! Its set-up which my CK25 is different than most motor and gear ratio is way different and tires size. Then add what body works for you. My body is the Blitz 60909.I've tried alot of bodys and have a different coming when it comes in. I also on black carpet and asphalt with changes to both except bodies.
