| 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. The test voltages used are based on a properly sized Li-Po battery for the current | ||||||||||||||
| draw of the motor being tested. If you are using a larger than normal capacity battery, or a very | ||||||||||||||
| high C-Rated battery, your actual voltages will be higher than those shown in this chart, and this | ||||||||||||||
| will result in higer current draw for each prop used. You should always test your power system | ||||||||||||||
| with a watt meter whenever a prop is used to ensure that you are not exceeding the recommended | ||||||||||||||
| rating of the motor being used. The prop recommendations in this chart are based on the motor | ||||||||||||||
| receiving adequate cooling throughout its operation. If your motor is being used inside a cowl, you | ||||||||||||||
| must provide adequate cooling to the motor and make sure that the motor is not getting too hot | ||||||||||||||
| during operation. | ||||||||||||||
