	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.
