I'm 3700 feet above sea level and am using Sidewinder Race 30/12. It will leave a faint trail of smoke...but nothing like a fuel with castor at a lower altitude. Don't use castor oils up here...gums up the motors.
bumm off street...the fuel you use and altitude you live in will also determine your proper tuning.
