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 80% power)
  The prop can be used, but full throttle should be kept to short bursts. (80 to 100% power)
  The prop is too big for the motor and should not be used. (Over 100% power)
PLEASE NOTE:
The Data contained in this Prop Chart is based on actual measurements, taken in a controlled test environment, at an altitude of
584 feet above sea level. The test voltages used are based on the standard output of a Li-Po battery under load, which is 3.70 volts
per cell. If you are using a battery that is larger in capacity than normal, or has a very high C-rating, then your actual voltages will
be higher than those shown in the chart, and this will result in a higher current and power value for every prop used. You should
always test your actual power system with a watt meter before flying your model to make sure that you are not exceeding the
recommended current and power ratings of the motor being used. The prop recommendations in this chart assume that the motor
receives adequate cooling throughout its operation. If your motor is being used inside a cowl or fuselage, you must ensure that
the motor receives sufficient airflow, and does not get too hot during operation. It is always best to use a prop size that pulls no
more than 80% of the motors maximum recommended current value to ensure safe operation under all conditions.
