| 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. | |||||||||||||||
