Programming the Kontronik SMILE and JAZZ ESC's The Kontronik Smile ESC's are nice inexpensive controllers for helicopters. The ESC has a governor mode which maintains headspeed independent of collective load and also has one of the best soft starts around. Once properly programmed for governor mode you can switch straight from off into an idle up and the ESC will very gradually spool up the motor. in Radiostyrt > Helikoptrarwith eschelicopterjazzkontronicprogrammingsmile
