What do the specs mean?

	The constant velocity of a motor measures the amount of times an unloaded motor rotates per minute (rpm) when 1v is applied. For example; a 1300KV motor powered by an 11.1V 3S LiPo battery would spin at 14,430 rpm (1300 x 11.1). The KV rating helps determine which motors are suitable for different types of aircraft. FPV racing drones require high rpm for greater speed, but heavy multi-rotor models would be better suited to motors with a low KV rating.
	The Watt rating of a motor is the measure of power being delivered. We recommend 100 - 150 watts of motor for every 1lb that the plane weighs. This is dependent on the type of flying that wants to be achieved. Aerobatic 3D-type flying would require more the 150W per 1lb, whereas chilled-out type flying would be more suited towards the 100W per 1lb end of the scale.
	All of our Tornado Thumper motors have been designed to work in conjunction with our own XP2 range of speed controllers.
	The recommended cell count of a motor is the minimum to maximum amount of cells within a battery pack required to power the motor.
	The recommended propeller size on the motors is dependent on the voltage of the battery that you are using in your set up. If you decide to run your motor with a higher voltage battery then you will need to alter the propeller size to avoid overloading. The rpm increases as more volts are applied therefore requiring a smaller sized prop. Always use a watt meter to determine the correct diameter and pitch of the prop for your exact set up.
