The 4240/10 890KV motor is part of Overlander's Tornado Thumper V3 range. These motors are manufactured to Overlander’s demanding standards, using the finest quality components and state of the art CNC machine tools.

he 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.
