A2212 Quadcopter Brushless Motor [2450KV]

Descriptions:
The A2212 is a brushless motor for quadcopters and multirotor drones. This RC aircraft brushless motor is designed for DIY fixed wing multi rotor aircrafts. With excellent quality and high performance, It meets the needs of the GoolRC racers. High quality materials include long life Japanese bearings, precision balanced rotor which makes this brushless motor very smooth and reliable, even at the maximum RPM. The metal gears help with the movement, they will rotate to the proper direction.
The brushless motors are way more powerful for their weight than brushed motors, and they last way longer. For bigger quads: no question, brushless is king. Brushless motor lasts longer because there are no brushes to wear out, while the brushed motor wears out quickly. That's one of the reasons brushed motors came out cheaper then brushless motors. The general rule of thumb is to aim for 2:1 thrust to weight ratio. You aren’t going to be able to do hard core racing with it. The higher the better obviously. The thrust to weight to ratio depends mostly on the size of the quads themselves. Theoreticly KV represents the speed at which the motor rotates for every volt applied to the motor. Higher the KV means lower resistance and higher current draw and lower efficiencies. Lower KV means higher resistance and lower current draw and considerably better efficiencies. If you’re starting out somewhere around 2300-2400 KV would be desirable.
