Propeller Chart Color Code Explanation
   The prop is to small to get good performance from the motor. (Less than 50% power)
   The prop is sized right to get good power from the motor. (50 to 90% power)
   The prop can be used, but full throttle should be kept to short bursts. (90 to 105% power)
   The prop is too big for the motor and should not be used. (Over 105% power)
