It is suggested that if possible, let the motor idle for a couple of minutes before shutting it down, especially if the model has been flown hard. By idling the motor just for a minute, it will cool down significantly and there will be less heat soak. Page 14 of 16 Copyright 12/5/2004 Miniature Aircraft USA... -
